Kevin O'Connor	5e6127869a	mcu: Do not invert the direction of pullup pins by default ... A pullup setting on an input pin (ie, '^') should enable the hardware pullup resistor, but it should not invert the trigger level (ie, it should remain trigger on high). Those that need to change the trigger level (ie, trigger on low) must now do that explicitly (ie, '^!'). This makes the code match what other firmwares do.

Kevin O'Connor	7f8a94ff48	heater: Make it possible to disable min_extrude_temp for testing ... Allow a config file to specify 'min_extrude_temp: 0' to disable the minimum extrude temperature test. This makes it easier to perform testing on the avr simulator. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>	2016-10-11 00:21:30 -04:00
Kevin O'Connor	af99ab1645	extruder: Create a new class and python file to track the printer extruder ... Create a new python file (extruder.py) to control the extruder heater and stepper motors. This separates the extruder control logic from the cartesian robot code - making it easier to customize both the kinematic control of the robot as well as the extruder.

Kevin O'Connor	bb3b881e21	docs: Change the debugging docs to recommend a serial baud rate of 250000 ... A baud of 250000 is a better choice for production use. It's better to test with that rate also. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>	2016-06-13 15:34:23 -04:00
