BL Probe deploys when Scanning Z probe cycles run

Invader_Zoom · 4 Aug 2024, 15:38

Hello all,
I'm looking for some assistance setting up my Scanning Z Probe. The trouble comes when attempting to run the M558.1 calibration. The calibration runs successfully; however, the BL touch probe deploys at the same time and leaves the BL probe in error status at completion of the calibration routine. This behavior persists despite specifying the K1 parameter with M558.1 (M558.1 K1 S1.5 example command) where the BL is configured as K0 and the SZP as K1. Similarly, when running the bed mesh (G29 K1) the BL probe deploys which will damage the probe as the pin drags across the bed.

While I could write a reset for the BL probe into a macro for M558.1 to solve the first issue I'm not aware of how I could similarly edit the G29 routine and this doesn't really address the root issue.

Any thoughts or advice is appreciated.

@Invader_Zoom Do you have any deployprobe files in your sys directory? If so what is in them?

Invader_Zoom · 4 Aug 2024, 17:13

@gloomyandy

Yes, I am using deployprobe.g and retractprobe.g subroutines containing a single M280 command each.

M280 P0 s10 extend

M280 P0 S90 retract

gloomyandy · 4 Aug 2024, 18:34

@Invader_Zoom Try renaming those to deployprobe0.g and retractprobe0.g at the moment I think it may be running your current files for both probes.

Invader_Zoom · 4 Aug 2024, 20:56

@gloomyandy Renaming the deploy and retract subroutines solved my issue. Thank you for your help.

@gloomyandy after spending all day fighting my SZP I finally stumbled upon your answer and it saved my brain from having a total meltdown. This really needs to be put into the official documentation asap. I really like my duet stuff but it's things like this that drive me nuts, the documentation is missing critical things like this. Thank you thank you!
