How to test the BLTouch Z probe

Jim Brown edited this page Apr 1, 2018 · 1 revision

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:

  1. M280 P0 S160
  2. M280 P0 S60
  3. make the position of the push-pin up or down by your finger
  4. M119
    ※ You can repeat from 3 to 4.

Pin down should be open, and pin up should be triggered.

You can’t perform that action at this time.
