Mach4 General Discussion / ESS not communicating to Mach 4
« on: February 11, 2018, 06:18:47 PM »
I am a total newbie. Please be patient.
Hardware: ESS rev 2 Build 216, BOB: C11G Board Rev 9, Home made CNC Router
Software: Mach 4 ver 2.0.3481 Demo Mode
5v power to both boards. 58.7v to stepper drivers.
Running Mach 4 in Demo mode I can not get stepper motors to move. Trying jog, keyboard and MDI.
All lights are lit. ESS top green is steady. Bottom green flashing. EStop is communicating with BOB and cleared.
Screen shows they are moving.
ESS Diagnostics in Mach 4 only show odd pins(dir?) working when keyboard is pressed.
My stepper driver documentation says they run enabled by default.
Do I need to change JP3 jumper?
I have double and triple checked wiring, connections port output settings. Watched as many videos as I can fathom.
Searched forums and at a loss.
Please help.
