bltouch



  • hello sorry but I could not completely set the bltouch I have a delta can you take a look at the configuration please? when i send the g29 or the g32 it goes home and goes down without the pin pulled out so i turn off (i also have a problem with the z axis in home i don't know why it stops before the endstop)
    thank you for your assistance

  • I have already created the folders deployprobe.g, retractprobe.g I have also tested the bltouch pin up, down, test works


  • Moderator

    Post your homedelta.g, bed.g as well.

    Do the probe deploys and retracts when you send M401 and M402?

    When you send G30 does the probe deploy?

  • m401 m402 g30 everything works

    (i also have a problem with the z axis in home i don't know why it stops before the endstop)

    Are you sure that your steps per mm is 80?


  • Moderator



  • @Phaedrux yes mm is 80 😕

    @nemecek said in bltouch:

    G1 H1 X405 Y405 Z405 F1800 ; move all towers to the high end stopping at the endstops (first pass)

    Try increasing the distance moved for the initial homing to ensure that it goes far enough to hit the endstops.

    That may solve one problem if you're sure 80 steps per mm is correct and it's moving the correct amount.



  • @Phaedrux yes I read but I don't know where I went wrong you can help me I'm really desperate


  • Moderator

    I'll do my best, unfortunately I'm not a delta guru. All I can really do is suggest to go through those docs carefully and try and understand what's going on. I can try and answer any specific questions.



  • ok
    thank you🙂


  • Moderator

    I'm hoping that if we resolve the initial homing the probing will fall into place. If M401 M402 and G30 work correctly to deploy the pin and cause the head to move towards the bed that means the probe itself is working correctly.

    That should do it.

    See this section



  • @Phaedrux good morning i read in your opinion should i delete it? G1 X0 Y0 F6000 ; move X+Y to the centre



  • @Phaedrux ok perfect I solved the problem of the z axis by deleting this G1 X0 Y0 F6000; move X + Y to the center now and only one bltouch problem you can do
    😊 😊



  • hi I managed to get it working by changing the P9 to the P5 should be P9
    peche? can you explain it to me?

    M558 P5 H5 F120 T3000

  • Moderator

    Yes the BLTouch should use P9.

    I'm curious now what firmware version you are running. Should be 2.05.1.
    Can you please send M122 and post the results?



  • yes

    So what exactly happens when you have it set to P9 and do this test?

  • it goes down without extracting the pin😭
