I draw using mastercam 9.1, then use the fanuc post to write the code, then use Universal G-code Sender to send the file to the arduino uno flashed with GRBL 1.1 to the 3 steppers I have on my mill. For some reason though, the feed always shows 0 even though my code very clearly states:

"G1 Z-.1 F8.21"

all the rapids are working correctly, but when it actually goes to cut, the feeds just read "0." Everything was working properly yesterday, I didn't change anything and nothing updated. Cant seem to figure this one out. I rechecked my grbl values and they also all check out
