Re: Mach3 mill stopped in the middle of a job.
开云体育Hi Chuck, I’m not suggesting try a jumper and then try running CNC.? I’m suggesting disable the charge pump and don’t reconnect it.? Whatever is required to do that.? Then start tracing signals again.? Click the big red button and make sure your hard wired ESTOP is not active.? Verify that with the LEDs on the PMDX board and the MACH software. Now JOG X in say + direction.? Look at the Parallel port DIR_X output at the PMDX input side.? Then look at the signal out to the X Axis GECKO DIR pin. Now JOF X in the – direction and see if the outputs change.? Without a scope it’s hard to see if the step pulses are making it through. ? Have you created a sketch or drawing of how your system is wired?? For example attached is the drawing I did for my ELS to Gingery lathe connection.? My ELS duplicates the Parallel port and I’ve had it running with both MACH2 and MACH3 by just moving the cable from the ELS to the PC. ? Also attached is an older version of my CNC Mill conversion with the PMDX-126.? Just to give you an idea of how to put something together that you can then share to help with diagnostics. ? Doesn’t have to be fancy done with CAD but at least something drawing with ruler lines etc.? ie. Neat and tidy.? That might even give you the clue as to what might be happening. John ? ?

John, I just tried changing the jumpers JP4 and that didn’t make any difference. I then change the jumper on JP3 and again no improvement.? ? When I say changed, I’m talking about changing them from the default configuration. ? ? For some reason, although I’m getting the proper voltages on the parallel port pins, they don’t seem to be having any effect on the PMDX board? ? Chuck?
