3D Touch Sensor:Auto-levelling for Geeetech 3D printer

[menestrello]

I confirm: after update to new firmware every problem was solved.

You should use the latest RCBugFix-branch if you can. It has some changes done to the 3DTouch/BLTouch code that makes it work better.

ive followed the settings you have suggested but iu just cannot seem to get my printhead to go low enough, any other settings to check ?

Loriz71:

You have changed your threaded rods so you are moving too slow for the probe.


Set DEFAULT_MAX_FEEDRATE to 4 for Z.
Also, you may need to set "#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2)"

Thank you for your answer NiklasO.
Yesterday I've tested your marlin RCbugfix with similar problems.
Tonight I test your solution.
[edit]
Many thanks to NiklasO, all work fine after changing DEFAULT_MAX_FEEDRATE 2 to 4 for Z.
I've tested last NiklasO RcBugfix marlin and work fine

Hello,

I confirm with the great help of NiklasO, My prusa i3 Pro B acrylic works great with the 3d touch sensor and the firmrware is the last new

I mount the 3dtouch sensor, then i calibrate the bed manual wih a sheet of paper to test the G29 with a good calibrated bed

This is the result of G28 and after a G29

But i just made a bed calibration, i suppose the difference between the 9 point in the real is near 0.1, if it is 1mm i can see it easy with a sheet of paper but it isn't.

Where is the problem?
