Setting Up and Calibrating Sensorless XY Homing

When using the TMC2130 / TMC2209 / TMC2660 / TMC5160 drivers, the StallGuard feature makes it possible to set up sensorless homing on the X and Y axes for CoreXY machines. The Klipper project has a page with documentation and recommendations on getting it working.

Following are some more detailed instructions and suggestions to supplement the Klipper documentation specifically for Vorons.

Create Info.plist

About

This script will update Info.plist of a target in XCode with the following

1. CFBundleVersion to the git commit count
2. GitDate to the date of the last commit
3. GitBranch to the current branch name
4. GitTag to the latest tag on current branch

Creates a .version file to track last update and appease XCode needing a non-mutable output path.

Autofs on Mac OS X

With autofs you can easily mount network volumes upon first access to the folder where you want to mount the volume. Autofs is available for many OS and is preinstalled on Mac OS X so I show you how I mounted my iTunes library folder using this method.

Prepare autofs to use a separate configuration file

autofs needs to be configured so that it knows where to gets its configuration. Edit the file /etc/auto_master and add the last line:

#
# Automounter master map
#

+auto_master # Use directory service
