Mechtronics 4 axis board and 3 Keling 8 wire steppers

[wgkurth]

I'm building a x-y cnc using a Mechtronics 4 axis board, 3 Keling 8 wire steppers (KL23H286-20-8B) and Mach 3 software. I'm having problems getting everything working.

I'm not sure wheither to set up the steppers series or parallel (2 different wiring configurations). Also I'm not sure if I have the Mach 3 is communicating with Mechtronics board - I'd like to just jog the motors knowing are connected and functional before I try g-code.

Can you point me the right direction to get this going?

Thanks,

Generally, the best wiring method for CNC would be Bipolar Parallel. The motors draw 2.8A and have a best Voltage of 83 Volts.

For maximum power, you would need to have a power supply as close to that best Voltage as possible--And that would probably be 72V. If your board cannot handle that Voltage, then you should select a Power supply as close to it as the board will tolerate.

Make sure your printer port is operational--Print something. Make sure you are using a straight thru male/male serial dB25 cable.

I'm not sure about the 4 axis board, but the three can only handle 36 V if I remember correctly. That's part of the reason I scrapped mine and went with a G540 instead...

edit: I just checked and it wants a 24V psu - nowhere near enough for what you a working with.
