New Lulzbot Mini which had issue of when attempting a followup (non cold start) print, the nozzle would attempt to wipe about 1cm above the pad. Then the nozzle would crash on each washer, noticeably deflecting the bed. However, it would pass the autolevel routine and start printing.
The first layer would not print since the nozzle was dragging on the PEI and no material could extrude. Once I saw this behavior, I would watch the machine like a hawk during print start and if I saw it “air wiping”, I would abort the print and shut down the machine and reload filament(since it retracted 30mm before the wipe).
Contacted support and they recommended upgrade Cura 2.6.63 (which was not released or available yet) and upgrade firmware and clear cache. A week later I was able to get new Cura and do this.
Now the wiipe function appears to work okay, but the nozzle does not go as deep into the cleaning pad as before. The nozzle touches the rear left washer fine, the front left washer fine, then lowers towards washer number 3 (front right) but aborts before touching the washer. Looks like it gets about 1mm away before aborting. It then attempts a nozzle wipe, but the wipe is useless since it is a couple mm above the pad. two more attempts and the autolevel procedure fails.
Any ideas or thoughts?
In the meantime I will perform another firmware update and see if there is any change in behavior.
