How to smoothly start movement for z-probing?

[mmueller70]

Hello!
Is there a way to have the Z switch approach motion start smoothly?
I drive the print bed up against the print nozzle, the bed rests on four piezo elements. However, these already respond at the start of the upward movement due to the inertial mass of the bed, so that I have to lower the sensitivity unnecessarily, which in turn is bad for my hotend. And I have to move fast at the end for secure triggering.

Greetings from Germany an a Happy New Year,

@mmueller70 if you are running firmware 3.4 or later you can use the M201.1 command to reduce the Z acceleration when probing. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m2011-set-reduced-acceleration-for-special-move-types.

Again and again I realize how good it was to choose a Duet board. If I miss a function, it's not because it doesn't exist, but because I can't find it in the multitude of functions.

Thanks
