Hello.

Randomly when auto homing the nozzle will stop too far from the bed. When this occurs, there is no audible click from the switch. Immediately auto homing a second time might work correctly (it's pretty random) with the z stop switch clicking as it should.
The bed is levelled correctly and the switch is properly placed. If it works, it prints perfectly but sometimes it will start a print too high.

Also, the Y axis is off centre. Centred objects will print closer to the front of the bed, by quite a few mm. It has been this way since purchase.

Any suggestions would be appreciated.
