Hi everyone.
I'm putting together my first CNC machine (router) and am looking for help getting my stepper motor drivers running. I know this site is mostly about the mach3 sofwtare, but I am hoping some one will recognize this problem and help me get going. Here is what I have:
X-axis= CW8060 driver (rated 6A), 5A stepper motor, 4 lead
Y-axis = CW230 driver (rated 3A), 2.7A stepper motor, 8 lead, wired in parallel
Z-axis = CW230 driver (rated 3A), 2.7A stepper motor, 8 lead, wired in parallel
BOB = unknown manufacturer, "rev5" from buildyourowncnc.com
I have the x-axis motor/driver running properly, but I can't get the y or z axis to move. What I have tried:
1- Moved the motor leads (at the driver) from the y-driver to the x-driver. The CW8060 driver will spin the smaller motors, so motors and connections must be OK
2- Moved the x-axis output from the BOB to the inputs on the y-axis driver - no movement
3- Confirmed via oscilloscope that the BOB is sending the same pulses to x-driver and y-driver
4- Replaced complete y-axis driver with new out of box- same no movement of Y or Z motor
5 - If I look at the x-axis motor leads on a scope, I see a 36V pulse when the motor is moving and nothing when the motor is idle.
6- If I look at the y-axis motor leads on a scope, I see a 72V (or +/-36V) pulse at all times (trying to move the motor or not)
7- Tried swapping CP and CW inputs on the y-axis drive with no success.
Thanks for any help you can provide
Chris
