can you help me with my issue im having, when i first turn on machine i cs machine then turn on spindle i get a c axis fault motor overload #9 so i reset board 1010-4 control board and it works fine been doing this for a few months. now when i do a tool change the spindle turns really slow and faults out saying c axis fault motor overload #18. The next time i do the tool change it may still go slow but it will work or it wont every other time. i called fadalcnc and they sent me a new 1010-4s board put it in and thought it help then it started doing the same thing after a hour. i did a zero memory procedure and seem to be fine for a few hours then back to faulting out.also change orientation factor from 15 to 25 help for a bit then got slow again and faulted any idea what i should try next? thanks
