Strange behavior with Bl touch
-
@Phaedrux , i tried all the options you suggested but i didn't get anything. Just out of curiosity because I didn't find detailed information, do you suggest putting ssr before or after load?

I'm sorry,I don't understand the question.

@Phaedrux, I have understand where the problem lies, I have a small motor very close to the probe, if I enable the motor before touching the bed it creates some disturbance at bltouch.
From what I read before I went with BLTouch sensors on all my machines, they're very sensitive to noise. To combat this, on all my machines I've threaded the wires through a braided shield I bought from McMasterCarr. It's paid of as I don't have any repeatability issues with any of them, and two of them run next to motors and heater wires. I do heat shrink both ends to prevent the braided shield from fraying.

@PDBeal ,great advice!! Thanks for the info
-
@Phaedrux, sorry for the bad english ...... I hope you can make understand otherwise I will make a drawing, do you recommend putting SSR before or after heated bed?
-
@Marco-Bona You would switch the live side, not the ground side.
But if the bed is 24v why use an SSR?
-
@Phaedrux ,I try to invert it, the bed is powered by 24v but I believe that the connection does not change.
Check it out and I'll update you, thanks -

@Phaedrux, just for safety

@Phaedrux, I finally managed to solve, all the fault of bad insulation of heated bed ...........
