My Lead CNC doesn't run smoothly when it is going in a circular (not straight path). I have attached a video to demonstrate what I am seeing. The cuts are still accurate but the machine slows down the cut. I am not sure if it is a problem with wiring, if it isn't running through the gcode fast enough or if the actual machine is out of alignment. If you have any ideas please let me know. Again the cuts are still accurate so I am making it work, it just slows everything down and is just concerning.
Could be a couple things 1) Gcode for review 2) Check that leadscrew is still tensioned (no axial play between leadscrew and endplates) 3) Check shaft couplers - not slipping on leadscrews? Check grubscrews tight and on the flat of the motor shaft 4) Do a couple cuts like circle-diamond-square tests
