I've gotta give Mariss kudos first. He has tried to help.
I have 4 G202's on a 3 axis machine. 2 of them run the X axis.
Machine specs:
Mach 3
PMDX 131 breakout board. www.pmdx.com
PMDX 135 power prep board
Avel Lindberg 800va torroidal transformer, 56vdc
homeshopcnc's rs34-960 960oz steppers: www.homeshopcnc.com
rated 7A per phase parallel.
All of this configured and assembled by Holt Control Systems.
The second x axis is wired to run directly off of the i/o from the first x axis. It's not configured as a slave drive in Mach. Although I have done this to no avail. Same issue.
I had problems with this drive earlier and sent it back to Gecko for testing. In the lag time, the owner of Holt Control Systems lent me his G202 drive. I used his drive for several months until he finally asked for it back last week. Mariss tested and said that the drive that I sent to him worked but when I plugged it back in today it quits just like before!
I ran out to Radio Shack today and got some 47ohm resisters to knock the voltage down. This was before I realized that Holt Control Systems had configured my steppers in parallel (7A) which is correct according to the specs on their site.
Anybody out there have any idea why this drive would quit but the loaner didn't? I had the loaner for 6 months without trouble. Any answers would be greatly appreciated.
BTW, There are NO loose wires in this control box. All ends are finished with mechanical connectors and screwed into it's matching block.
