I have had my WorkBee 1010 with Blackbox for over 2 years with very little problem. Lately, it has stopped running one of the motors- X, Y, or Z - sometimes mid-job! Initially I thought it was a wiring issue, so I would disconnect, remove power and check the wiring- tightening the screws or stripping and reconnecting the ends to the motor. Then it would function normally. I just figured out that simply turning it off & on again will "reset" it and it functions again for a time- although the functional time is getting shorter and shorter. Any thoughts or similar experiences out there?
Does the FAULT LED light up? docs:blackbox-4x:currentadjustment [OpenBuilds Documentation] If it gets worse over time, it may just be dust build up on the heatsink fins.
If the FAULT LED does not light its probably not overheating, but still a little maintenance doesn't hurt. Check the fan too Or perhaps you've not noticed the LED, if so, keep an eye out next time it happens
