Hi guys,

I have just purchased and installed this G540 4 axis kit.

All of the motors, in any combination, seem to work correctly by themselves, or two or three of them plugged into the G540, but as soon as all 4 of them are connected at the same time, I get a fault anywhere from 5 seconds to 30 seconds later.

The motors are 3.5 Amp per phase,
Power supply is 48 Volt 12.5 Amp,
All of the motors have 3.48K resistors installed on their DB9 connectors.

I'm at a loss, but the issue seems to have something to do with power supply, or the resistor setting, as it only ever occurs when 4 motors are connected, sometimes even without moving them.

I've read other threads, which all mention power supply, but then ppl point out 7 Amps should be fine, and I'm not even moving the motors sometimes. I have 18 Gau wire between the power supply and the gecko.

Any thoughts?

Nick
