I preheat to 170°c. That allows the filament to be soft enough to be cleaned (with tweezers or a brush) without oozing. Then I do a 10mm retract before probing.
Comment on Don't forget to change your z offset after swapping nozzles
skilltheamps@feddit.de 1 year agoHow do you handle residual filament on the nozzle from previous prints? Or if you heat it up to get to nozzle itself to touch the bed, do you get dabs of plastic distributed around your bed?

My probe hits my z endstop, so similar idea. I preheat my probe and manually wipe it before I home. Any ooze doesn’t really make a difference in first layer. At some point I’ll print a purge bucket and nozzle brush…
My endstop is just a metal rod, but since it’s cold filament doesn’t stick to it. If I were probing my bed I would probably want a hot nozzle and cold bed.
