3DTouch sensor problem (clone of BLTouch)
Hi all forumites.
I have a problem with a 3DTouch sensor and I'm not sure if it's the firmware or a sensor problem. I've enabled auto bed levelling in Repetier 1.0.3 and setup the sensor like many explained on the web and this forum.
My problem is sending the lower command "M340 P0 S700", the sensor doesn't always just dropdown. It sometimes "bounces".
See the video I have uploaded here:
The command sent in the video was:
M340 P0 S1500
M340 P0 S700
And this was repeated 5 times. Has anybody had this problem before?
All the commands for the sensor works like expected except the dropdown command. For completeness, here's a list of all the commands:
M340 P0 S700 (Probe start script) <--- This bounces sometimes
M340 P0 S1500 (Probe finished script) <--- Always work correctly
M340 P0 S1800 (Self-test) <--- Always work correctly
M340 P0 S2200 (Alarm Release) <--- Always work correctly
M340 P0 S1200 (M119 Test Mode) <--- Always work correctly

Any help or suggestions would be appreciated.

I believe this is enough evidence to show a faulty probe unless someone on this forum has found a solution.
Although the values seem to work, it still had that problem
