Hi everyone.
In the old workshop there were no problems with the plasma cnc table and the motors turning. After disassembly and reassembly in another workshop we have a very strange problem. The stepper motors will not turn when jogging from the mach3 software (https://www.oyostepper.es/).
We changed the cables and for the new setup he used a cat6 double shielded cable. We use 2 breakout boards: one for motor control, enable commands, X,Y,Z limit switches and one for controlling ARC on and thc control. Both breakout boards seem to be working. I can enable disable steppers, the limit switches are working (input ports are from the first breakout board) and I see that when I switch the limit switches manually. The enable command is sent using the output pin 14 of the first BB, the Z motor is connected to pins 4,5, the X motor to pin 67 and the Y to pins 8 and 9.
When I power the motors the motors are locked, when I press the Estop key the motors unlock, but when I jog I can see the modification of the X,Y,Z values in the mach GUI but the motors remain stationary. I have already changed: a) the breakout board, the stepper drivers, the lpt cables, the motors, changed the lpt ports. We use a software that monitors the lpt output and it seems that the output from mach3 is correctly going to the lpt port.
I really don't know what to do next, what to check. It could be that the cable I'm using is faulty, but I tested it with the motors directly connected to the driver with the same result. The weird thing is that all motors X,Y and Z have the same problem.
If anyone knows how to debug this problem it would be great.
