Geeetech

Yhank you for the answer

I followed the wiki instructions and the offset is saved well by the M500 command

Hello !
I mounted the 3D sensor on my geeetech prusa i3 pro B and it works, but I have to calibrate the z offset for each print.
The offset can change to 0.4 mm and the first layer becomes bad.

Is it normal to have to calibrate the z offset before each printing?

Someone has an idea?

Thank you !
