Not been on here for a long time but I am now trying to convert an old Denford Triac PC & I am having trouble with all 3 axis jogging.
So it's an old Triac but not connected to original control box. Desktop PC running Windows 7 pro, not connected to internet & all power saving features & updates either off or disabled. UCCNC software with 2017 screenset, UC 400 ETH motion control, original stepper motors, cw5045 drivers, clo-10v breakout board & linear power supply which is kicking out about 43.5 volts.
Problem is that I am not 100% sure if I have the stepper motor wires round the right way, a+ a- b+ b- for one thing. When I try to jog any axis sometimes it moves & sometimes the dros move but motor does not turn. Seems to be random. Sometimes it jogs + & - fine on each axis but then suddenly one direction on an axis stops working. Normally the + direction
