Does spindle.0.revs increase or decrease in M4 mode?
For info, G76 is interpreted here:
github.com/LinuxCNC/linuxcnc/blob/master...erp_convert.cc#L5029
And seems to be written for both spindle directions ( github.com/LinuxCNC/linuxcnc/blob/master...erp_convert.cc#L4887 )
I haven't tracked the signals far enough through the system to find where the synch happens, but have you tried using a negative pitch for negative spindle speed?

spindle.0.revs increases in M4 mode. I tried with negative pitch and it works, thanks!
