After chatting with the gecko folks, it finally was suggested that I send the unit in, since the error light comes on the moment power is applied with no cable present. I believe the error was caused since I had added a cable extender (purchased, I did not make it) on my 4th axis. I have since removed that cable, went back to the original cabling.
While waiting for the controller return, I plan to ohm out all the motor wires, checking the resistors, winding continuity, and looking for shorts. I'm presuming if all 4 axies read the same on all connections, then there is not a motor failure, but a cockpit error with the new cable somehow.....
If anyone has any additional checks, please let me have'em.....
Thanks...... Henri
