 - BUT when the Y stepper moves the gantry, the length of the X belt on either side of the gantry is affected and thus the X stepper must also move to compensate

 Luckily this kinematic is supported by both Klipper and the stock Marlin firmware (with a small modification). After you've printed the parts for at least stage 1, just follow the instructions in the [firmware section](/docs/firmware) to use the new kinematic.

-## Vz Printhead

+{% capture vz %}
 **Usable Print Area:** 220 x 200 (20mm reduction on Y axis)
 
+The Vz Printhead is an impressively simple printhead used on the blazing fast VzBot printer. It has all the features you'd expect from a modern printhead including many popular hotends, extruders, and Z probes (BLTouch and SuperPINDA). It also as well as some less-common features like adjustable-height fan ducts and CPAP cooling.
+
+The only drawback with this printhead is that you may not already have the [30mm standoffs](https://speedyfpv.com/products/10pcs-m3x30mm-aluminum-spacer-standoff-silver-anodized?variant=37983057936557) on hand to complete the build (< $10 with shipping).
+
+The official design only required three parts to be modified in order to work on the Endorphin. So start by downloading the official STLs from [here](https://github.com/VzBoT3D/Vz-Printhead-Printed/tree/main/STLs) and you can find the BOM [here](https://github.com/VzBoT3D/Vz-Printhead-Printed/tree/main/BOM). Then before you start printing parts, check the table below and substitute any of the original parts listed below with the Endorphin part:

 ### Belt Clips
 
-Either of the following belt clips provided with the printhead will work fine so pick whichever one you prefer. The original Vz printhead has been modified so that the posts sit at the right height for the Endorphin belts. Just remember that you only need to print off clips for 2 belt ends rather than the 4 needed in a CoreXY, which means you can choose whether you want to attach the belt ends on the front or rear posts. The other two will be unused.

 You also don't need to print `face_belt_grabber.stl` because the Endorphin doesn't have a belt that attaches to the front of the EVA in the same way that a CoreXY does.
