My Morgan seems to have 2 different positions that the z-axis homes to. Sometimes it is at exactly the right height. Other times it’s a couple mm too low (plastic doesn’t stick to platform). Have you seen this behavior or know how I could fix it?
I can do a redesign of the sensor holder to make it slide past in stead of approaching it head-on. It could be that you have some magnetic interference close to the sensor… are there any motor wires passing close by the sensor?
Yes, I’m using the hall effect sensors. There doesn’t appear to be any motor wires nearby. The firmware that senses the endstops is interrupt-driven, not polling, correct? I’m not sure that a slide-past would improve things.
