first of all, sorry for my bad english, i’ll do my best to be understood
I am trying to use klipper on my old prusa i3 from emotion-tech (2015) wich runs on an arduino atmega 2560. Everything works fine but the bed mesh leveling.
What happens : the printer starts probing (2 samples per probe point) with it’s capacitive sensor. After a few probing points, it randomly stays close to the bed (don’t lift back up) then go to the next point and then inevitably return the “probe trigered prior to movement” wich is normal since the printer didn’t lift it’s head.
It seems like the arduino just “lags” and skip the instructions sent by the rpi.
What also happens sometimes is that the printer “half-skip” the command and just lift up a portion of the normal Z height wich makes it probing from less high for the next points.
It’s pretty weird and hard to explain, i’ll try to make a video if you need to. But here you can see a heightmap that finished with that bug (i hope it uploaded well )
