Hi Everyone,
Just got around to replacing the C2 caps on the stepper motor controller boards for a mate, and now im testing all of the electronics.
Seems like the X and Y Axis connections are working. Im not seeing anything on the Z axis. When I power the motherboard up, the X and Y stepper motor controllers appear to be in an idle state (one green and red led on for each board), but on the Z axis, I get a dim flash of a red LED for about half a second, then nothing.
Ive checked the ribbon cables and the stepper motors and boards, and they all seem fine. My mate had the bootloader flashed and the motherboard sits there with the debug LED flashing at 1Hz.
I am about to test the motherboard with the scope now and see if I can come up with anything.
Any help would be great!
Liam
