Topic: Mini W auto calibration
I'm having issues with calibrating the bed on my DaVinci Mini W printer. Normally when you run the bed auto calibration routine, after you lower the detector, the printer will home the z axis, then detect on the corner of the bed, then home and detect again. Presumably this is a check to make sure that both the z limit switch and detector are working correctly. I'm assuming they are looking for a change in motor steps between runs.
Anyway on my machine this cycle does not happen just once but keeps going for a very long time, eventually either erroring out or finally catching and then running the rest of the calibration routine. The question is why?
I'm assuming either my z axis limit switch is buggy, or my detector switch is buggy, but it is possible that the motor driver is borked or the coupler on the z threaded rod is loose. I was hoping someone else may have an idea of where to start looking.
