Can't get 3 Point leveling Zprobe to work

Hi. I have a cartesian style printer and a AZSMZ board and I’ve been fighting with the bed leveling. When I run a g32, the printer homes all axis, comes down for the first probe, then the Z axis makes a terrible “you set your feedrate too high” noise, then proceeds to the remaining 2 points without moving the probe up. I tried searching the forum but couldn’t find a solution. I also tried grid leveling, but the same thing happens.

Speed going up is twice speed going down, when probing.

Divide your probing speed by two or more.

Cheers.

Even with zprobe.return_feedrate 3?

Thank you for supporting me!

What you are describing, is speed being too high when returning. Severely reduce all speeds ( in particular return ), and try again.

Cheers.

I guess I can’t argue. I changed slow feedrate to 1 and it worked flawlessly. That’s even with return feedrate still set at 3. Since smoothie is designed to run leveling once and save, this should be fine.

Thanks again for support
