How to test the BLTouch Z probe
If your brand new BLTouch (genuine or most clones) does not seem to be working properly, here's how to test it.
Connect your printer to your computer and use a host program (I like Pronterface) to do the following:
- M280 P0 S160
- M280 P0 S60
- make the position of the push-pin up or down by your finger
※ You can repeat from 3 to 4.
Pin down should be open, and pin up should be triggered.
