Trigger height whitout Z probe



  • I removed my Z probe and manual probing the bed.
    How can I remove the trigger height. After probing my Z go to 5.7 mm. In the dwc I see the trigger height at 0.7mm. RRF3.0 duet2 WiFi. No probe in the config.g file.



  • please post your config.g

    G31 XYZ in config.g sets the probe offsets.

    Are you using M558 probe type P0 for manual probing? or what exactly do you mean about manual probing?

  • G31 is missing so you dont set a offset



  • Is that necessary if you don't use a probe?



  • good question ... try it, it will cost nothing 😉

    @gorie said in Trigger height whitout Z probe:

    That's a good question, I'm not sure. For a nozzle contact probe the X and Y are 0, but sometimes the Z value is still used. Such as the case if you used a feeler gauge to set the height on the bed, you would have G31 X0 Y0 Z0.2. If you are touching the bed directly, you would have Z0. I would assume that the P value would also be irrelevant, but you could still set it to some value just in case.
