Scanning Z probe G31: invalid Z probe index

charliedrums

Ok, so I have the scanning z probe connected M122 B120 command works and I get communication with the board.

But all I get when I start the duet is:

1/31/2024, 9:29:52 PM 	Error: G31: invalid Z probe index

I’m running RRF 3.5rc3 A toolboard 1LC and the Z scanning probe is connected to the tool distribution board. Is the scanning probe supported on a tool distribution board? Any help would be greatly appreciated.

share your full config g please

dc42

@charliedrums without seeing your full config.g file we can only guess at the cause. My guess is that you need to add a delay command such as G1 S4 near the start of config to allow time for the SZP board to start up before you address it in the M558 K1 command.

Your SZP does not seem to be running 3.5.0-rc.3. Probably best to make sure all of the boards are using the same version.

@gloomyandy I run in SBC and I did try to do an update but it did not update the Scanning probe board. Should I run it again?

@oliof I triedthe G1 S4 after the G4 S2 but still get the G31: invalid Z probe index

A bit more info on my setup.
I have the 1LC board connected to Tool0 connection on the tool distribution board and the scanning z probe on Tool1 I left the BYPASS jumpers on the on Tool 1 and I also soldered the termination resistor jumper on the back of the scanning Z Probe board.

@charliedrums said in Scanning Z probe G31: invalid Z probe index:

uet SZP firmware version 3.5.0-rc.1+ (2023-11-20 12:50:20)

Your SZP does not seem to be running 3.5.0-rc.3. Probably best to make sure all of the boards are using the same version.

Totally brain farted, this was the issue. I was trying to update the SZP board trough putty with sudo apt update but it kept saying everything was updated. Fetched the rc3 update bin file for the SZP from the github directory and uploaded it trough DWC and installed it from there. That seemed to be my problem. I don't get the G31: invalid Z probe index at start up anymore. Thanks everyone for the help.
