Alternative way #32

Closed TypQxQ closed 2 years ago

Wanted to show an alternative way to do this with off the shelf hardware and only gcode commands. I made the Knobprobe for probing Z offset between nozzle and Z-Probe.

With this probing method you need a pretty flat print bed. But if your print bed is a little bit wobbly and you'll need a mesh compensation, then it's better to use a method like Klicky or BLT probe...

Nice! But this is a completely different approach. I'm always aware of thermal expansion or changing signal speeds due to thermal impact since I do print ABS in a closed printer (although, this may not in issue for every one). Your probe does not use any electronics and is mostly of plastic, so it seems pretty well for you. But, with this approach, you don't need to place a probe on the bed manually before every print. Ah, you make me thinking... with a multi tool head printer.. it may be sufficient to do this routine with one print head and just probe the nozzle of the other print heads 🤔
