@Ralms instead of relais and optocoupler you might find a simple inverter/driver chip with optocoupled input in the good'ol 74hcxxx series.

@jay_s_uk said in Prevent docking and undocking of probe during multiple G30 Pn:

@Ralms call M401 to undock the probe and then do all your probing routines. That should prevent it docking it between.
Then M402 at the end

That did the trick.
Thank you!

Need to look into submitting some documentation improvements after finishing coding the printer lol

@Ralms said in Using G30 S0 inside homez.g fails:

The issue I'm raising now, is that G30 will execute from the console, even if deployprobe.g fails, it just ignores it and that should never happen.

G30 works from the console or from within a macro, whether the Z axis is homed or not. The X and Y axes must be homed. When G30 is called, it will run deployprobe.g if the probe type requires it. When and why might deployprobe.g fail, and how would it know if deployprobe.g has failed? If running G30 from the console, it could possibly be too low to fully deploy, eg BLTouch, or off the bed, but I'd say this was operator error rather than the firmware's fault. You could have a check in deployprobe.g for current Z height, if it is below say 2mm, or if the axis is unhomed, move up 5mm. The stock homez.g from the configuration tool moves the Z axis up 5mm before homing to avoid this.

@jay_s_uk said in Duet 3 Standalone update from 3.3.0 to 3.4.0 failed:

@ralms https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#all-other-duet-boards
fallback procedure 2 using bossa

Well, after delaying this process for a few days, expecting a nightmare and headache knowing what to do, it was actually fairly painless.

After flashing the board with Bossa its back to working normally.

Just one suggestion regarding the documentation, the Bossa section is missing a last step just confirming that we are free to reset or disconnect the board from USB and use it normally.

Thank you.

@Ralms said in RepRapFirmware 3.2.2 update question:

've noticed that there is no "Duet3and3Firmware-3.2.2.zip" combined file.

I have now added that file and announced the 3.2.2 release. The IAP file is unchanged from firmware 3.2.

@Ralms Thanks for the example. Unfortunately, we are rather limited by the Dozuki software (developed and used by ifixit.com) we use for documentation. There's no drop down selection, tabbed content or even ability to hide sections. It would be good to have documentation specific for each board and RRF version, but that would mean a lot of duplication of pages, so it's a case of putting the most relevant information first, then having notes for other variations. Not ideal, but all that can be done within the current limitations.

We're always on the look out for alternatives (preferably open source or at least with a low cost of entry), particularly if the existing documentation can be ported easily, so welcome any suggestions.

I've got the same motor and I dremmeled a flat. I clamped it to a table and used electrical tape to protect the innards. Took all of 5 minutes., which was worth it to me to guarantee no slipping on the shaft. Though droftarts makes some points I hadn't considered at all.
