Autobed leveling problem

Post by Ripoli » Wed Apr 04, 2018 12:07 pm

Hello, i have some problem with my Geeetech Prusa I3 Pro W. After configurating the autobed with this tutorial: ... ing_Sensor
The home funktion works great. The Nozzle is walking to the mid and the sensor works great.
But if i start a print the nozzle walks down to the bottom and hits the plate. So why is he not checking the second time?

"M280 P0 S90"
"M280 P0 S120"

Just got my 3D touch installed today, had been sitting around in my spares box for about a month now. If you want the bed to be probed multiple times at each point in the bed levelling method you've chosen you need to tell the firmware to do that. A little bit below where you set the X, Y and Z offsets for the probe there is a line to do this, look for


Remove the // to uncomment this and with the above setting the points will all be probed twice, once at normal speed and the second time at half speed (this can be modified too if you want).

Hope this helps.
