topic_solved Cant print anymore!
My printer used to print fine until yesterday. Every print fails from the start now and looking closely it looks like the Z axis is lifting up and then back down on the first layer.
I tried to re-establish Z=0 using my calibrate Z Probe macro and my suspicions of Z lifting were confirmed. I can no longer jog Z down to bite a piece of paper because when it gets to a certain position close to gripping the paper Z starts to lower instead of raising!
I'm on firmware 2.03 beta 3.
I find it strange that @gnydick is having similar problems when baby-stepping
Does the behaviour persist if you switch back to firmware 2.02?
I haven't had chance to do it yet. I will let you know the outcome cheers.
Can you post more information? Config file, homing files, your probe calibration macro, details about the printer and z axis. Video of the problem. Greatly helps in tracking down the root issue.
I found the issue.
There were problems with the gcode in a couple of macros regarding setting up the z-probe and mesh bed levelling that did not become apparent until I made a slight alteration with the physical position of my ir-probe.
Thanks for your help though.
