-### Generic Cartesian Kinematics
-
-See [example-generic-cartesian.cfg](../config/example-generic-caretesian.cfg)
-for an example generic Cartesian kinematics config file.
-
-This printer kinematic class allows a user to define in a pretty flexible
-manner an arbitrary Cartesian-style kinematics. In principle, the regular
-cartesian, corexy, hybrid_corexy can be defined this way too. However,
-more importantly, various otherwise unsupported kinematics such as
-inverted hybrid_corexy or corexyuv can be defined using this kinematic.
-
-Notably, the definition of a generic Cartesian kinematic deviates
-significantly from the other kinematic types. It follows the following
-convention: a user defines a set of carriages with certain range of motion
-that can move independently from each other (they should move over the
-Cartesian axes X, Y, and Z, hence the name of the kinematic) and
-corresponding endstops that allow the firmware to determine the position
-of carriages during homing, as well as a set of steppers that move those
-carriages. The `[printer]` section must specify the kinematic and
-other printer-level settings same as the regular Cartesian kinematic:
-```
-[printer]
-kinematics: generic_cartesian
-max_velocity:
-max_accel:
-#minimum_cruise_ratio:
-#square_corner_velocity:
-#max_z_velocity:
-#max_z_accel:
-
-```
-
-Then a user must define the following three carriages: `[carriage x]`,
-`[carriage y]`, and `[carriage z]`, e.g.
-```
-[carriage x]
-endstop_pin:
-#   Endstop switch detection pin. If this endstop pin is on a
-#   different mcu than the stepper motor(s) moving this carriage,
-#   then it enables "multi-mcu homing". This parameter must be provided.
-#position_min: 0
-#   Minimum valid distance (in mm) the user may command the carriage to
-#   move to.  The default is 0mm.
-position_endstop:
-#   Location of the endstop (in mm). This parameter must be provided.
-position_max:
-#   Maximum valid distance (in mm) the user may command the stepper to
-#   move to. This parameter must be provided.
-#homing_speed: 5.0
-#   Maximum velocity (in mm/s) of the carriage when homing. The default
-#   is 5mm/s.
-#homing_retract_dist: 5.0
-#   Distance to backoff (in mm) before homing a second time during
-#   homing. Set this to zero to disable the second home. The default
-#   is 5mm.
-#homing_retract_speed:
-#   Speed to use on the retract move after homing in case this should
-#   be different from the homing speed, which is the default for this
-#   parameter
-#second_homing_speed:
-#   Velocity (in mm/s) of the carriage when performing the second home.
-#   The default is homing_speed/2.
-#homing_positive_dir:
-#   If true, homing will cause the carriage to move in a positive
-#   direction (away from zero); if false, home towards zero. It is
-#   better to use the default than to specify this parameter. The
-#   default is true if position_endstop is near position_max and false
-#   if near position_min.
-```
-
-Afterwards, a user specifies the stepper motors that move these carriages,
-for instance
-```
-[stepper my_stepper]
-carriages:
-#   A string describing the carriages the stepper moves. All defined
-#   carriages can be specified here, as well as their linear combinations,
-#   e.g. x, x+y, y-0.5*z, x-z, etc. This parameter must be provided.
-step_pin:
-dir_pin:
-enable_pin:
-rotation_distance:
-microsteps:
-#full_steps_per_rotation: 200
-#gear_ratio:
-#step_pulse_duration:
-```
-See [stepper](#stepper) section for more information on the regular
-stepper parameters. The `carriages` parameter defines how the stepper
-affects the motion of the carriages. For example, `x+y` indicates that
-the motion of the stepper in the positive direction by the distance `d`
-moves the carriages `x` and `y` by the same distance `d` in the positive
-direction, while `x-0.5*y` means the motion of the stepper in the positive
-direction by the distance `d` moves the carriage `x` by the distance `d`
-in the positive direction, but the carriage `y` will travel distance `d/2`
-in the negative direction.
-
-More than a single stepper motor can be defined to drive the same axis
-or belt. For example, on a CoreXY AWD setups two motors driving the same
-belt can be defined as
-```
-[carriage x]
-endstop_pin: ...
-...
-
-[carriage y]
-endstop_pin: ...
-...
-
-[stepper a0]
-carriages: x-y
-step_pin: ...
-dir_pin: ...
-enable_pin: ...
-rotation_distance: ...
-...
-
-[stepper a1]
-carriages: x-y
-step_pin: ...
-dir_pin: ...
-enable_pin: ...
-rotation_distance: ...
-...
-```
-with `a0` and `a1` steppers having their own control pins, but
-sharing the same `carriages` and corresponding endstops.
-
-There are situations when a user wants to have more than one endstop
-per axis. Examples of such configurations include Y axis driven by
-two independent stepper motors with belts attached to both ends of the
-X beam, with effectively two carriages on Y axis each having an
-independent endstop, and multi-stepper Z axis with each stepper having
-its own endstop (not to be confused with the configurations with
-multiple Z motors but only a single endstop). These configurations
-can be declared by specifying additional carriage(s) with their endstops:
-
-```
-[extra_carriage my_carriage]
-primary_carriage:
-#   The name of the primary carriage this carriage corresponds to.
-#   It also effectively defines the axis the carriage moves over.
-#   This parameter must be provided.
-endstop_pin:
-#   Endstop switch detection pin. This parameter must be provided.
-```
-
-and the corresponding stepper motors, for example:
-```
-[extra_carriage y1]
-primary_carriage: y
-endstop_pin: ...
-
-[stepper sy1]
-carriages: y1
-...
-```
-Notably, an `[extra_carriage]` does not define parameters such as
-`position_min`, `position_max`, and `position_endstop`, but instead
-inherits them from the specified `primary_carriage`, thus sharing
-the same range of motion with the primary carriage.

-[input_shaper]

-[delayed_gcode init_shaper]

-```
-Note that `SHAPER_TYPE_Y` and `SHAPER_FREQ_Y` must be the same in both
-commands in this case, since the same motors drive Y axis when either
-of the `x` and `u` carriages are active.

-The `X`, `Y`, and `Z` parameters are used to alter the low-level

-then the position is not changed - for example `SET_KINEMATIC_POSITION
-Z=10` would set all axes as homed, set the internal Z position to 10,

-position tracking is not dependent on the internal homing state - one
-may alter the position for both homed and not homed axes, and
-similarly one may set or clear the homing state of an axis without
-altering its internal position.
-
-The `SET_HOMED` parameter defaults to `XYZ` which instructs the
-kinematics to consider all axes as homed. A bare
-`SET_KINEMATIC_POSITION` command will result in all axes being

-request an individual axis be considered homed (eg, `SET_HOMED=X`),
-but note that non-cartesian style kinematics (such as delta

-
-The `CLEAR_HOMED` parameter instructs the kinematics to consider the

-all axes to be considered not homed (and thus require homing prior to
-movement on those axes). The default is `SET_HOMED=XYZ` even if

-## Using `LOAD_CELL_DIAGNOSTIC`
-
-When you first connect a load cell its good practice to check for issues by
-running `LOAD_CELL_DIAGNOSTIC`. This tool collects 10 seconds of data from the
-load cell and resport statistics:
-
-```
-$ LOAD_CELL_DIAGNOSTIC
-// Collecting load cell data for 10 seconds...
-// Samples Collected: 3211
-// Measured samples per second: 332.0
-// Good samples: 3211, Saturated samples: 0, Unique values: 900
-// Sample range: [4.01% to 4.02%]
-// Sample range / sensor capacity: 0.00524%
-```
-
-Things you can check with this data:
-
-* The configured sample rate of the sensor should be close to the 'Measured
-  samples per second' value. If it is not you may have a configuration or wiring
-  issue.
-* 'Saturated samples' should be 0. If you have saturated samples it means the
-  load sell is seeing more force than it can measure.
-* 'Unique values' should be a large percentage of the 'Samples
-  Collected' value. If 'Unique values' is 1 it is very likely a wiring issue.
-* Tap or push on the sensor while `LOAD_CELL_DIAGNOSTIC` runs. If
-  things are working correctly this should increase the 'Sample range'.
-
-## Calibrating a Load Cell
-
-Load cells are calibrated using the `LOAD_CELL_CALIBRATE` command. This is an
-interactive calibration utility that walks you though a 3 step process:
-
-1. First use the `TARE` command to establish the zero force value. This is the
-   `reference_tare_counts` config value.
-2. Next you apply a known load or force to the load cell and run the
-   `CALIBRATE GRAMS=nnn` command. From this the `counts_per_gram` value is
-   calculated. See [the next section](#applying-a-known-force-or-load) for some
-   suggestions on how to do this.
-3. Finally, use the `ACCEPT` command to save the results.
-
-You can cancel the calibration process at any time with `ABORT`.
-
-### Applying a Known Force or Load
-
-The `CALIBRATE GRAMS=nnn` step can be accomplished in a number of ways. If your
-load cell is under a platform like a bed or filament holder it might be easiest
-to put a known mass on the platform. E.g. you could use a couple of 1KG filament
-spools.
-
-If your load cell is in the printer's toolhead a different approach is easier.
-Put a digital scale on the printers bed and gently lower the toolhead onto the
-scale (or raise the bed into the toolhead if your bed moves). You may be able to
-do this using the `FORCE_MOVE` command. But more likely you will have to
-manually moving the z axis with the motors off until the toolhead presses on the
-scale.
-
-A good calibration force would ideally be a large percentage of the load cell's
-rated capacity. E.g. if you have a 5Kg load cell you would ideally calibrate it
-with a 5kg mass. This might work well with under-bed sensors that have to
-support a lot of weight. For toolhead probes this may not be a load that your
-printer bed or toolhead can tolerate without damage. Do try to use at least 1Kg
-of force, most printers should tolerate this without issue.
-
-When calibrating make careful note of the values reported:
-
-```
-$ CALIBRATE GRAMS=555
-// Calibration value: -2.78% (-59803108), Counts/gram: 73039.78739,
-Total capacity: +/- 29.14Kg
-```
-
-The `Total capacity` should be close to the theoretical rating of the load cell
-based on the sensor's capacity. If it is much larger you could have used a
-higher gain setting in the sensor or a more sensitive load cell. This isn't as
-critical for 32bit and 24bit sensors but is much more critical for low bit width
-sensors.
-
-## Reading Force Data
-Force data can be read with a GCode command:
-
-```
-LOAD_CELL_READ
-// 10.6g (1.94%)
-```
-
-Data is also continuously read and can be consumed from the load_cell printer
-object in a macro:
-
-```
-{% set grams = printer.load_cell.force_g %}
-```
-
-This provides an average force over the last 1 second, similar to how
-temperature sensors work.
-
-## Taring a Load Cell
-Taring, sometimes called zeroing, sets the current weight reported by the
-load_cell to 0. This is useful for measuring relative to a known weight. e.g.
-when measuring a filament spool, using `LOAD_CELL_TARE` sets the weight to 0.
-Then as filament is printed the load_cell will report the weight of the
-filament used.
-
-```
-LOAD_CELL_TARE
-// Load cell tare value: 5.32% (445903)
-```
-
-The current tare value is reported in the printers status and can be read in
-a macro:
-
-```
-{% set tare_counts = printer.load_cell.tare_counts %}
-```

-## Load Cell Probe Safety
-
-Because load cells are a direct nozzle contact probe there is a risk of
-damage to your printer if too much force is used. The load cell probing system
-includes a number of safety checks that try to keep your machine safe from
-excessive force to the toolhead. It's important to understand what they are
-and how they work as you can defeat most of them with poorly chosen config
-values.
-
-#### Calibration Check
-Every time a homing move starts, load_cell_probe checks
-that the load_cell is calibrated. If not it will stop the move with an error:
-`!! Load Cell not calibrated`.
-
-#### `counts_per_gram`
-This setting is used to convert raw sensor counts into grams. All the safety
-limits are in gram units for your convenience. If the `counts_per_gram`
-setting is not accurate you can easily exceed the safe force on the toolhead.
-You should never guess this value. Use `LOAD_CELL_CALIBRATE` to find your load
-cells actual `counts_per_gram`.
-
-#### `trigger_force`
-This is the force in grams that triggers the endstop to halt the homing move.
-When a homing move starts the endstop tares itself with the current reading
-from the load cell. `trigger_force` is measured from that tare value. There is
-always some overshoot of this value when the probe collides with the bed,
-so be conservative. e.g. a setting of 100g could result in 350g of peak force
-before the toolhead stops. This overshoot will increase with faster probing
-`speed`, a low ADC sample rate or [multi MCU homing](Multi_MCU_Homing.md).
-
-#### `reference_tare_counts`
-This is the baseline tare value that is set by `LOAD_CELL_CALIBRATE`.
-This value works with `force_safety_limit` to limit the maximum force on the
-toolhead.
-
-#### `force_safety_limit`
-This is the maximum absolute force, relative to `reference_tare_counts`,
-that the probe will allow while homing or probing. If the MCU sees this
-force exceeded it will shut down the printer with the error `!! Load cell
-endstop: too much force!`. There are a number of ways this can be triggered:
-
-The first risk this protects against is picking too large of a value for
-`drift_filter_cutoff_frequency`. This can cause the drift filter to filter out
-a probe event and continue the homing move. If this happens the
-`force_safety_limit` acts as a backup protection.
-
-The second problem is probing repeatedly in one place. Klipper does not retract
-the probe when doing a single `PROBE` command. This can result
-in force applied to the toolhead at the end of a probing cycle. Because
-external forces can vary greatly between probing locations,
-`load_cell_probe` performs a tare before beginning each probe. If you repeat
-the `PROBE` command, load_cell_probe will tare the endstop at the current force.
-Multiple cycles of this will result in ever-increasing force on the toolhead.
-`force_safety_limit` stops this cycle from running out of control.
-
-Another way this run-away can happen is damage to a strain gauge. If the metal
-part is permanently bent it will change the `reference_tare_counts` of the
-device. This puts the starting tare value much closer to the limit making it
-more likely to be violated. You want to be notified if this is happening
-because your hardware has been permanently damaged.
-
-The final way this can be triggered is due to temperature changes. If your
-strain gauges are heated their `reference_tare_counts` may be very different
-at ambient temperature vs operating temperature. In this case you may need
-to increase the `force_safety_limit` to allow for thermal changes.
-
-#### Load Cell Endstop Watchdog Task
-When homing the load_cell_endstop starts a task on the MCU to trac
-measurements arriving from the sensor. If the sensor fails to send
-measurements for 2 sample periods the watchdog will shut down the printer
-with an error `!! LoadCell Endstop timed out waiting on ADC data`.
-
-If this happens, the most likely cause is a fault from the ADC. Inadequate
-grounding of your printer can be the root cause. The frame, power supply
-case and pint bed should all be connected to ground. You may need to ground
-the frame in multiple places. Anodized aluminum extrusions do not conduct
-electricity well. You might need to sand the area where the grounding wire
-is attached to make good electrical contact.
-
-## Load Cell Probe Setup
-
-This section covers the process for commissioning a load cell probe.
-
-### Verify the Load Cell First
-
-A `[load_cell_probe]` is also a `[load_cell]` and G-code commands related to
-`[load_cell]` work with `[load_cell_probe]`. Before attempting to use a load
-cell probe, follow the directions for
-[calibrating the load cell](Load_Cell.md#calibrating-a-load-cell) with
-`CALIBRATE_LOAD_CELL` and checking its operation with `LOAD_CELL_DIAGNOSTIC`.
-
-### Verify Probe Operation With LOAD_CELL_TEST_TAP
-
-Use the command `LOAD_CELL_TEST_TAP` to test the operation of the load cell
-probe before actually trying to probe with it. This command detects taps,
-just like the PROBE command, but it does not move the z axis. By default, it
-listens for 3 taps before ending the test. You have 30 seconds to do each
-tap, if no taps are detected the command will time out.
-
-If this test fails, check your configuration and `LOAD_CELL_DIAGNOSTIC`
-carefully to look for issues.
-
-Load cell probes don't support the `QUERY_ENDSTOPS` or `QUERY_PROBE`
-commands. Use `LOAD_CELL_TEST_TAP` for testing functionality before probing.
-
-### Homing Macros
-
-Load cell probe is not an endstop and doesn't support `endstop:
-prove:z_virtual_endstop`. For the time being you'll need to configure your z
-axis with an MCU pin as its endstop. You won't actually be using the pin but
-for the time being you have to configure something.
-
-To home the axis with just the probe you need to set up a custom homing
-macro. This requires setting up
-[homing_override](Config_Reference.md#homing_override).
-
-Here is a simple macro that can accomplish this. Note that the
-`_HOME_Z_FROM_LAST_PROBE` macro has to be separate because of the way macros
-work. The sub-call is needed so that the `_HOME_Z_FROM_LAST_PROBE` macro can
-see the result of the probe in `printer.probe.last_z_result`.
-
-```gcode
-[gcode_macro _HOME_Z_FROM_LAST_PROBE]
-gcode:
-    {% set z_probed = printer.probe.last_z_result %}
-    {% set z_position = printer.toolhead.position[2] %}
-    {% set z_actual = z_position - z_probed %}
-    SET_KINEMATIC_POSITION Z={z_actual}
-
-[gcode_macro _HOME_Z]
-gcode:
-    SET_GCODE_OFFSET Z=0  # load cell probes dont need a Z offset
-    # position toolhead for homing Z, edit for your printers size
-    #G90  # absolute move
-    #G1 Y50 X50 F{5 * 60}  # move to X/Y position for homing
-
-    # soft home the z axis to its limit so it can be moved:
-    SET_KINEMATIC_POSITION Z={printer.toolhead.axis_maximum[2]}
-
-    # Fast approach and tap
-    PROBE PROBE_SPEED={5 * 60}  # override the speed for faster homing
-    _HOME_Z_FROM_LAST_PROBE
-
-    # lift z to 2mm
-    G91  # relative move

-### Suggested Probing Temperature
-
-Currently, we suggest keeping the nozzle temperature below the level that causes
-the filament to ooze while homing and probing. 140C is a good starting
-point. This temperature is also low enough not to scar PEI build surfaces.
-
-Fouling of the nozzle and the print bed due to oozing filament is the #1 source
-of probing error with the load cell probe. Klipper does not yet have a universal
-way to detect poor quality taps due to filament ooze. The existing code may
-decide that a tap is valid when it is of poor quality. Classifying these poor
-quality taps is an area of active research.
-
-Klipper also lacks support for re-locating a probe point if the
-location has become fouled by filament ooze. Modules like `quad_gantry_level`
-will repeatedly probe the same coordinates even if a probe previously failed
-there.
-
-Give the above it is strongly suggested not to probe at printing temperatures.
-
-### Hot Nozzle Protection
-
-The Voron project has a great macro for protecting your print surface from the
-hot nozzle. See [Voron Tap's
-`activate_gcode`](https://github.com/VoronDesign/Voron-Tap/blob/main/config/tap_klipper_instructions.md)
-
-It is highly suggested to add something like this to your config.
-
-### Nozzle Cleaning
-
-Before probing the nozzle should be clean. You could do this manually before
-every print. You can also implement a nozzle scrubber and automate the process.
-Here is a suggested sequence:
-
-1. Wait for the nozzle to heat up to probing temp (e.g. `M109 S140`)
-1. Home the machine (`G28`)
-1. Scrub the nozzle on a brush
-1. Heat soak the print bed
-1. Perform probing tasks: QGL, bed mesh etc.
-
-### Temperature Compensation for Nozzle Growth
-
-If you are probing at a safe temperature, the nozzle will expand after
-heating to printing temperatures. This will cause the nozzle to get longer
-and closer to the print surface. You can compensate for this with
-[[z_thermal_adjust]](Config_Reference.md#z_thermal_adjust). This adjustment will
-work across a range of printing
-temperatures from PLA to PC.
-
-#### Calculating the `temp_coeff` for `[z_thermal_adjust]`
-
-The easiest way to do this is to measure at 2 different temperatures.
-Ideally these should be the upper and lower limits of the printing
-temperature range. E.g. 180C and 290C. You can perform a `PROBE_ACCURACY` at
-both temperatures and then calculate the difference of the `average z` at both.
-
-The adjustment value is the change in nozzle length divided by the change in
-temperature. e.g.
-
-```
-temp_coeff = -0.05 / (290 - 180) = -0.00045455
-```
-
-The expected result is a negative number. Positive values for `temp_coeff` move
-the nozzle closer to the bed and negative values move it further away.
-Expect to have to move the nozzle further away as it gets longer when hot.
-
-#### Configure `[z_thermal_adjust]`
-Set up z_thermal_adjust to reference the `extruder` as the source of temperature
-data. E.g.:
-
-```
-[z_thermal_adjust nozzle]
-temp_coeff=-0.00045455
-sensor_type: temperature_combined
-sensor_list: extruder
-combination_method: max
-min_temp: 0
-max_temp: 400
-max_z_adjustment: 0.1
-```
-
-## Continuous Tare Filters for Toolhead Load Cells
-
-Klipper implements a configurable IIR filter on the MCU to provide continuous
-tareing of the load cell while probing. Continuous taring means the 0 value
-moves with drift caused by external factors like bowden tubes and thermal
-changes. This is aimed at toolhead sensors and moving beds that experience lots
-of external forces that change while probing.
-
-### Installing SciPy
-
-The filtering code uses the excellent [SciPy](https://scipy.org/) library to
-compute the filter coefficients based on the values your enter into the config.
-
-Pre-compiled SciPi builds are available for Python 3 on 32 bit Raspberry Pi
-systems. 32 bit + Python 3 is strongly recommended because it will streamline
-your installation experience. It does work with Python 2 but installation can
-take 30+ minutes and require installing additional tools.
-
-```bash
-~/klippy-env/bin/pip install scipy
-```
-
-### Filter Workbench
-
-The filter parameters should be selected based on drift seen on the printer
-during normal operation. A Jupyter notebook is provided in scripts,
-[filter_workbench.ipynb](../scripts/filter_workbench.ipynb), to perform a
-detailed investigation with real captured data and FFTs.
-
-### Filtering Suggestions
-
-For those just trying to get a filter working follow these suggestions:
-
-* The only essential option is `drift_filter_cutoff_frequency`. A conservative
-  starting value is `0.5`Hz. Prusa shipped the MK4 with a setting of `0.8`Hz and
-  the XL with `11.2`Hz. This is probably a safe range to experiment with. This
-  value should be increased only until normal drift due to bowden tube force is
-  eliminated. Setting this value too high will result in slow triggering and
-  excess force going through the toolhead.
-* Keep `trigger_force` low. The default is `75`g. The drift filter keeps the
-  internal grams value very close to 0 so a large trigger force is not needed.
-* Keep `force_safety_limit` to a conservative value. The default value is 2Kg
-  and should keep your toolhead safe while experimenting. If you hit this limit
-  the `drift_filter_cutoff_frequency` value may be too high.
-
-## Suggestions for Load Cell Tool Boards
-
-This section covers suggestions for those developing toolhead boards that want
-to support [load_cell_probe]
-
-### ADC Sensor Selection & Board Development Hints
-
-Ideally a sensor would meet these criteria:
-
-* At least 24 bits wide
-* Use SPI communications
-* Has a pin can be used to indicate sample ready without SPI communications.
-  This is often called the "data ready" or "DRDY" pin. Checking a pin is much
-  faster than running an SPI query.
-* Has a programmable gain amplifier gain setting of 128. This should eliminate
-  the need for a separate amplifier.
-* Indicates via SPI if the sensor has been reset. Detecting resets avoids
-  timing errors in homing and using noisy data at startup. It can also help
-  users
-  track down wiring and grounding issues.
-* A selectable sample rate between 350Hz and 2Khz. Very high sample rates don't
-  turn out to be beneficial in our 3D printers because they produce so much
-  noise
-  when moving fast. Sample rates below 250Hz will require slower probing speeds.
-  They also increase the force on the toolhead due to longer delays between
-  measurements. E.g. a 500Hz sensor moving at 5mm/s has the same safety factor
-  as
-  a 100Hz sensor moving at only 1mm/s.
-* If designing for under-bed applications, and you want to sense multiple load
-  cells, use a chip that can sample all of its inputs simultaneously. Multiplex
-  ADCs that require switching channels have a settling of several samples after
-  each channel switch making them unsuitable for probing applications.
-
-Implementing support for a new sensor chip is not particularly difficult with
-Klipper's `bulk_sensor` and `load_cell_endstop` infrastructure.
-
-### 5V Power Filtering
-
-It is strongly suggested to use larger capacitors than specified by the ADC chip
-manufacturer. ADC chips are usually targeted at low noise environments, like
-battery powered devices. Sensor manufacturers suggested application notes
-generally assume a quiet power supply. Treat their suggested capacitor values as
-minimums.
-
-3D printers put huge amounts of noise onto the 5V bus and this can ruin the
-sensor's accuracy. Test the sensor on the board with a typical 3D printer power
-supply and active stepper drivers before deciding on smoothing capacitor sizes.
-
-### Grounding & Ground Planes
-
-Analog ADC chips contain components that are very vulnerable to noise and
-ESD. A large ground plane on the first board layer under the chip can help with
-noise. Keep the chip away from power sections and DC to DC converters. The board
-should have proper grounding back to the DC supply.
-
-### HX711 and HX717 Notes
-
-This sensor is popular because of its low cost and availability in the
-supply chain. However, this is a sensor with some drawbacks:
-
-* The HX71x sensors use bit-bang communication which has a high overhead on the
-  MCU. Using a sensor that communicates via SPI would save resources on the tool
-  board's CPU.
-* The HX71x lacks a way to communicate reset events to the MCU. Klipper detects
-  resets with a timing heuristic but this is not ideal. Resets indicate a
-  problem with wiring or grounding.
-* For probing applications the HX717 version is strongly preferred because
-  of its higher sample rate (320 vs 80). Probing speed on the HX711 should be
-  limited to less than 2mm/s.
-* The sample rate on the HX71x cannot be set from klipper's config. If you have
-  the 10SPS version of the sensor (which is widely distributed) it needs to
-  be physically re-wired to run at 80SPS.
