Hi community!
I'm having trouble with my cartesian style printer. The X-axis sometimes experiences step loss, about once every few hours, just enough to destroy most of the prints. I've tried following things so far:
1. As I wanted to change the electronics boary anyway, I switched from Ramps 1.4 to Duet 2 Ethernet. (and from Marlin firmware to reprap firmware)
2. Because the step loss persisted, I exchanged the motor with a new one.
3. Then I thought it might be a mechanical problem but the carriage is going very smoothly with hardly any resistance when I remove the belt.
4. After this I replaced the wires and all connectors to the motor because I suspected a loose connector.
5. I reduced speed to 40mm/sec, acceleration to 1000mm/min and jerk to 3mm/s.
Now after changing board, motor, wires, firmware and configuration I'm quite at a loss what I might yet try.
I don't think the motor is overheating because it is cooled by a 40mm fan and is cool to the touch when printing.
I've just realized that the step loss is as far as I remember mostly while going in the positive x direction, so the print is shifted towards the endstop.
The holding torque of the motor after homing is quite strong. While moving, I think moving in the positive x direction requires less force to stop than while moving in the opposite direction but still I thing it needs enough force that I doubt this is the problem.
Thank you in advance for sharing your ideas about my problem!
