M62-M68 codes not working was created by Cdub
I can figure out why my feed rate percentages and thc on/off isn’t working. Feed rate is just constantly the same and doesn’t change unless I change it manually and thc doesn’t turn off unless I turn it off manually. The g code commands are doing nothing. G code attached bellow. I made a new install media with 9.4 and reinstalled linuxcnc completely just to make sure I wasn’t out of date with anything.

I also tested the default qtplasmac preamble instead of the preamble outputted by the pronest post pro to see if that had anything to do with it but didn’t change anything.

The code (at least the code in your first post), works fine on 2.10.008.064. I realize you are on some version of 2.9, just was easy for me to test on that.
Can you state the specific version of 2.9 you are on (like above, as taken from the window title with QtPlasmaC open)?
Back when, there was a commit that temporarily broke feed reductions, but it was fixed. I honestly can’t remember if it was in 2.9 or master or both, but perhaps you have an older version that has the bug.

M62 and friends need connections in HAL to have any effect. Do these connections exist? (motion.digital-out-NN etc)
