Hi, Finally got to startup but no motors running, I have tried all the suggested info from machsupport but no joy, my first thought was the Stepper motor PSU I got from ebay was 24volts 15amps BUT it wasn't after checking realized they sent me a 12volt 30amp OK but should still have worked, the steppers Drivers are TB6600 and BOB is an ECG-Savebase, first thought was BOB PCGND needs connecting to motor PSU GND but then saw schematic showing opto-coupled inside TB6600 so +5V goes to all +ve on TB6600 and connections from BOB Pulse Dir go to -ve of TB6600.
I then put a scope on BOB output connections and jogged X,Y,Z I did have some signals on PULSE output a train of about 10 pulses then a couple of second gap and again then same then a gap of about 10 seconds and again pulses high varied from 5V to about 2v, the signal on DIR went from 0v to 5v when jogging from X Left to X right and same on all others, so should I be able to see a pulsed signal from these PULSE output, my scope connection was from PC 5V connection and one of the output connections.
Checked Jog which is 50%
Parallel pins are 2,3 X axis 3,4 Y axis 5,6 Z axis
Also tried Enable active Low/High which I have on pin 14 no diffference.
Grateful for any help.
Regards John
