Ender 3 v2 with BLTouch intermittent failure
I just received my v2 and Creality BLTouch kit. Board version 4.2.2. Updated to latest firmware: "4.2.2 Ender-3 v2 Marlin2.0.1 BLtouchV1.1.1without adapter board firmware.rar"
Everything works fine 1/2 times. But, every other print or so, one of the the probing attempts fails with the BLTouch blinking red and the head crashing into the surface. When it works, it's fantastic.
I have tried the following with no effect.
- Reseated connectors on the BLTouch and the main board.
- Routed the cable differently in case it was some electrical interference.
Anyone else have this issue? Were you able to solve it?
I am also having trouble with the head randomly crashing into the print bed even while trying to auto home. maybe 1 out of 20 times.
