Klipper Configuration

This is the Klipper config for my modded machine.

I have this cloned into a folder named machine, and my printer.cfg looks like:

#Mainsail config
[include mainsail.cfg]


# System
[menu __main __octoprint]
type: disabled


# Other Config

[include machine/machine.cfg]

X-Axis / Dual Z Alignment

I'm going to convert this idea to Klipper eventually.

Example, description and GCode in this reddit post by u/willsside. Also explained in their Mechanical Endstops for Z Axis Alignment project on Thingiverse.

I'm including their GCode below for posterity.

; Align X Axis Gantry / Calibrate Dual Z Steppers

; Similar to M915: Mechanical Alignment

G28 ; Home all axes

G0 Z250 ; Go to Z Top Max

M211 S0 ; Disable Software Endstops

G91 ; Relative Positioning

G0 Z10 ; Move up 10 mm to push into mechanical endstops and align stepper steps

G0 Z-10 ; Move down 10 mm

G90 ; Absolute Positioning

M211 S1 ; Enable Software Endstops

G28 ; Home all axes

;G29 ; ABL - BLTouch

M18 S0 Z ; Prevents the idle disabling of the z-steppers

Footnotes

  1. The C is written on the SD Card slot, and indicates the stepper driver type ↩

  2. I planned to do a belt driven dual Z mod, but then I learned that you can "auto-level" the x axis by carefully stalling the Z against end stops, see X-Axis / Dual Z Alignment. ↩
