Forgot to say that the controller is an YooCNC USB.

Very odd.

The line "G92 Z0" should set Z to 0 for every offset, yet in the video Z seems to be reset to 0.125 after this line then it jumps back 2 lines to the "G0 Z2" line. Does G92 have a special meaning through YooCNC or something?

Try entering the MDI command "G92 Z0" manually to see what happens.

G92 Z0 works fine in MDI.

Also did the sequence in MDI and all commands work successfully
G0 Z25
G1 X0 Y0 F1000
G0 Z2
G31 Z-1 F5
G92 Z0
G0 Z2

Mach3 error log after run autoleveller gcode.

Aha I think ive seen the error.

Mach3 doesnt like comma decimal separators so when it hits the line "G31 Z-1 F2,5" thats where the error occurs. It should be a point not a comma for the feed rate, i.e. "G31 Z-1 F2.5"

Did the gcode file come from AE0.7.6 because I thought I had fixed this issue before then?

For a quick workaround you can do a "find and replace" in a text editor to switch the commas into points. I will check and fix as necessary though.
