Last Klipper update

[yet-another-average-joe]

I've been using KnobProbe_Klipper for 18 months as a auto Z offset endstop, after a few trivial modifications. With : BLTouch, BQ Microprobe, and a couple of DIY Klicky's. Worked flawlessly.
Until the last Klipper update...
The probe "extra" was refactored, and killed KnobProbe_Klipper.
Attempted to "repair" it, but miserably failed.

Are you considering an update in the future ?

Hi! Thank you for the update. I will try to find some time this week. Do you happen to have any more info? Error medsages and what exactley has changed?/Andrei12 juni 2024 kl. 19:07 skrev yet-another-average-joe ***@***.***>: I've been using KnobProbe_Klipper for 18 months as a auto Z offset endstop, after a few trivial modifications.

Thanks for your answer !
Not much info.
Last known good Klipper is v0.12.0-207 / g6cd17420 (I rolled back !)

Access to probe attributes was changed.
Also, there's something with the multi probe begin and multi probe end procedures.
I'm not fluent with Python, and even less with the Klipper object model, unfortuanately... Had a hard time customizing KnobProbe !

Maybe this could be interesting : https://github.com/protoloft/klipper_z_calibration
It was updated very quickly, and could contain some usefull information

protoloft/klipper_z_calibration@4115614

I searched for other "extra" probes, but found nothing usefull (for now...) .

On Klipper forum (it doesn't really help) :

https://klipper.discourse.group/t/printerprobe-error-after-commit-d4bae4d/16967/3

The Beacon probe was quicly updated too (but looks unrelated) :

beacon3d/beacon_klipper@61266a4

Other "extra", that was not updated (but could be soon ?), and I never tested :

https://github.com/hawkeyexp/auto_offset_z

The last one ; not a probe, but accesses it : Dockable Probe by CloakedCode and Mental (seems to me CloakedCode is active on Discord/Armchair Heavy Industry / Danger-Klipper, but not sure). Played a bit with this plugin, before I discovered yours and gave up with Klicky's and magnets falling apart. There was a PR on Klipper Git, but it was never merged. Maybe he will update it ?

Klipper3d/klipper#6247

https://github.com/cloakedcode/klipper/blob/work-annex-probe/klippy/extras/dockable_probe.py

Unfortunately, I can't really help...

[EDIT] found another recently updated probe :

https://github.com/viesturz/klipper-toolchanger/blob/main/klipper/extras/tool_probe.py

Keep in mind I don't use KnobProbe as it is intended to be used (as CNC Z probe if I understand correctly) ; I tweaked it to be a nozzle probe and a reference point for measuring variations in the Z offset (nozzle Z - probe triggering point Z). Based on a standard Voron Z endstop. It works fine as a Z endstop, along with the virtual endstop. I don't have a tool changer.

I had time for tinkering with the new probe...
Remembered that knobprobe is based on probe. Using winmerge on one side (comparing probe and knobprobe), I created a new knobprobe, and edited it so the code looks similar to what the "old" knobprobe is doing.
At this point, I just verified that knobprobe is recognized, and reports valid information with QUERY_KNOBPROBE. Success.
Maybe is it a good starting point ? Too late for testing the other commands. It's 4:00 AM where I live. Sleepy...

Reworked the "stock" probe, and turned it into a knobprobe. Seems to be working as expected.

Just one detail : I don't remember if the toolhead is supposed to go back to its initial position after the command "KNOBPROBE"... The new knobprobe doesn't, and stops with the probe "TRIGGERED" (no big deal). Remember I didn't use it as you do, and added code for auto Z offset in PRINT_START + auto SET_GCODE_OFFSET, with more attributes in printer.cfg, and a calibration command that saves the reference value into printer.cfg

The archive contains a working knobprobe, not the auto Z offset plugin (somme more testing to do and features to add )

The results with Klipper v0.12.0-239-g433fcb6f :

Thank you!I started doing the same but I am entrrtaining 6 kids for a couple more days so limited time for anything else right now…/Andrei17 juni 2024 kl. 02:35 skrev yet-another-average-joe ***@***.***>: Reworked the "stock" probe, and turned it into a knobprobe.

Really good work @yet-another-average-joe! Thank you!
I had hoped to have time but, kids and life....
I tested it and it works as expected. Thank you!
I just edited the headers so Kevin won't get blamed for the code and published it.

Great !
