Recieved my g540 back from gecko on Saturday from a repair on the y-axis-- which went down mid-program. Hooked it up and everything seemed great. Ran good all weekend... X-axis went down this time-- again mid program. With the y-axis, I had no holding torque and it wouldn't come out of fault. This time, it comes out of fault and has holding torque, but no motion. all other axes function properly, and no motors function when hooked to x-axis drive. Also, the x-axis motor functions on any other drive.
Is it time for another trip to gecko already? If so, any ideas why its failing so rapidly?
The note from gecko for the first repair suggested i'd reversed polarity on the drive, which doesn't seem likely mid-program. Repair was for a cooked mosfet.
Running linuxcnc, keling 381oz steppers, keling 48v supply, 3.3k resistors. No apparent shorts on wiring.
i'd appreciate ANY help I can get here, I can't come up with anything wrong on my end-- but I cant imagine the failure rate on gecko's is anything close to this high
