I recently purchased an AntClabs BlTouch sensor from 3D Printing Canada, and it has become a major source of frustration for me for the past day.
I first started with installing Jyers Fork of Marlin Firmware and tried to tune the BlTouch via the Z-Offset. I made sure my GCode add line
G28 before I started my print. I made sure the bed was level, and that a Piece of paper was snug against the nozzle beforehand. I press print… and the nozzle was too low, causing a clog and scratching my bed.
I played around with it some more with it resulting in more failures. I then made the decision to flash Creality’s fork of Marlin for the BlTouch. Tried again, tried my best to tune the Z-Offset, resliced the file for good measure, and same issue.
While playing around with it, I noticed that even when I set the Z-Offset to where the paper was not snug against the nozzle, the printer would still send the nozzle low into the bed.
If anyone has any suggestions that would be very appreciated!
