Yeah - I might open it up and see if I can find a serial number or something for the unit, and pass that to Gecko

I think Automation tech are sending Gecko a power supply, ( the same as mine ) to see if they can figure out what the issue is, should be this week sometime, in the meantime, all I can do is hookup the 48 Volt pwr supply and check the amperage, but because it spikes so fast, I don't think it will register on the multimeter

At least I can discount the voltage as the culperate, otherwise the 3 motors or two motors connected would cause the same issue - seems to be current draw related
