I’m still chasing gremlins, but I have some more information that may generate some new ideas.
?
There have been a lot of inputs so far and I have addressed them with no joy.?
so here is where I am currently.
Summary:
?
I have a PDMX- 122 and Gecko drivers on my Table top TAIG 4 axis milling machine. Using MACH3.?
?
It’s been running fine for years and then all of a sudden in the middle of a job it stopped.
?
I checked the voltages for the direction pins on the XYZ axis And they each registered 3.5 V and 0.2V when checking the direction pins.
Does this voltage sound correct?
?
I also checked the voltage on the charge pump, and it registered the same.
although I am getting these voltages coming out of the parallel port cable, I am not getting any voltage on the PMDX – 122 board itself. When I try to move an axis.?
?
?
From everything I’ve checked so far the problem appears to be either in the PDMX – 122 board itself or some setting in MACH3 that is not set properly.?
?
Is there a way I can troubleshoot this board??
I have tried the PMDX forum, but it appears to be having a problem currently.?
any additional help would be greatly appreciated,
?thanks,
Chuck?
