Auto Bed Levelling in Marlin not raising after probing
Posted: Wed Apr 17, 2019 2:59 am
Hi.
I'm trying to get auto bed levelling working with my Geeetech I3 Pro B. I'm using the latest Marlin firmware and a capacitive fixed mounted sensor (self-made as replacement of the z min switch). Zero point detection is working probably and also the auto bed levelling is almost running the complete procedure. The only important thing I can't get working is the raising of the Z axis after probing. The probing is always continuing from the last found Z end position. That means for a bed that falls down from probe point 1 to N it would theoretical working. BUT this is never the case and from my understanding after every probing the z axis should raise about 10mm and than move to the next position. also for more than one tries at one probe position I would expect it will raise before next probing.
I have attached a zip file including my Configuration.h and also a serial plot of the auto bed levelling in debug mode. Thanks to all contributors upfront!
