Hello Everyone!
I would appreciate some guidance here...
I purchased a 3 axis HobbyCNC EZ Rev0 Chopper driver board and soldered it together. Tested voltage as per instructions and its correct.
Power supply is a Meanwell NES 350-24v with 14.6 amps output
I am trying to run 3 Powermax II P22NRXG-LNN-NS-00 stepper motors
My computer is a Windows 7 machine and did not come with a parallel port, so I purchased a PCI-E 1284 DB25PIN card and installed it. I also purchased a cable and tested it for continuity with my multimeter, the pins are indeed straight-through (some posts suggested weird wiring inside the cable could cause issues)
I have the 8 wire motors wired up as:
B - blue
b - orange
COM - 2 black wired into one COM terminal
COM - other 2 black wired into other COM terminal
a - red
A - yellow
Using Mach 3 I have the Ports & Pins setup as:
X axis pins 2, 3
Y axis pins 4,5
Z axis pins 6,7
Everything else I can see is set to Pin 1.
I plug this baby in, turn it on and I cannot seem to get anything to happen. No noises, no nothing.
What simple but painfully obvious step have I missed here?
I appreciate your help!
