Is there a way to edit the GCODE that controls the XYZ zeroing process?

I hacked my probing code enough to get a custom probe block to work. The aluminum block I have is 1.1811" square by .5906" high.

  1. Download the source code for the firmware at:
    https://github.com/OneFinityCNC/onefinity-firmware

  2. Extract the download and edit the following file:
    onefinity-1.0.9-20211217.tar\bbctrl-1.0.9\src\py\bbctrl\http\ index.html

  3. Around line 20,210 I modified the following ORIGINAL code

G91 G0 X ${mm(20)}
G91 G0 Z ${mm(-plunge)}
G38.2 X ${mm(-20)} ${speed(fastSeek)}
G91 G1 X ${mm(1)}
G38.2 X ${mm(-2)} ${speed(slowSeek)}
G92 X ${mm(xoffset)}

G91 G0 X ${mm(1)}
G91 G0 Y ${mm(20)}
G91 G0 X ${mm(-20)}
G38.2 Y ${mm(-20)} ${speed(fastSeek)}
G91 G1 Y ${mm(1)}

To be the following:
G91 G0 X ${mm(10)}
G91 G0 Z ${mm(-plunge)}
G38.2 X ${mm(-40)} ${speed(fastSeek)}
G91 G1 X ${mm(1)}
G38.2 X ${mm(-2)} ${speed(slowSeek)}
G92 X ${mm(xoffset)}

G91 G0 X ${mm(20)}
G91 G0 Y ${mm(10)}
G91 G0 X ${mm(-10)}
G38.2 Y ${mm(-40)} ${speed(fastSeek)}
G91 G1 Y ${mm(1)}
G38.2 Y ${mm(-2)} ${speed(slowSeek)}

  1. Use SSH to login to the Onefinity and upload the new index.html file, overwriting the original.

If you go to the release channel at

https://github.com/OneFinityCNC/onefinity-release

…you can download the ZIP file (using the green Code button/drop-down list) which contains all versions.

Or, if you SSH into your OneFinity, you could just pull down the active index.html from the machine itself.

Hey Forrest,

by the way, Markdown, as supported here in discourse.org forum software, allows nice automatic syntax highlighting for Diffs in Unified Diff format (and for a lot of other languages):
