BIQU Microprobe with 6HC.

[yagodajm]

BIQU Microprobe with 6HC. Good afternoon, I am replacing my BLtouch with a BIQU Microprobe. I recently did the same thing a while back on my other DIY printer and had great help here. I tried to use similar code, but I am running into issues. I am I think it may be the firmware versions as I am using the newer firmware on my new printer. The probe triggers on startup 3 times like normal. When I go to home the probe moves to the center of the bed and the probe deploys and the bed starts to move up, but the probe triggers before the bed even gets close and I get a M42 error code. Does anyone know what I am missing? I have my BL touch code commented out.

Thanks,
Justin

@yagodajm your M950 is wrong for the probe. You're creating a servo output with the S0 but you should be using P0 instead as the output for a microprobe isn't a servo

[yagodajm]

@jay_s_uk Ok, I changed S0 to P0 and I am still getting the same error. Any other ideas?

Thanks,
Justin

[jay_s_uk]

@yagodajm is it a v1 or v2 microprobe?

[yagodajm]

@yagodajm V2. I got it, I have to invert the pin.
