👋 simcnc 3.6 beta crashes the plasma torch into the workpiece, even with thc disabled. 3.4 didnt have this issue.

Here's the super simple gcode

I tried disabling THC via setting anti-dive velocity to 100% but did not help.

Downgrading tomorrow - if you folks have any ideas let me know.

 

M220 changes feedrate, you can ignore those if you dont have the script. Consistent crash ramming torch into steel going from N60 to N65
