Hi,

I´m trying for hours now to get that toolchanger working. I´m using Tap and I want the toolchanger to detect which Head is mounted through the specific endstop. The first thing is, when one probe is mounted and the other one is not, I get the following output:

23:59
Multiple probes not triggered:

from:

23:59
DETECT_ACTIVE_TOOL_PROBE

So both having the same endstop status? When trying to activate a tool to check the endstops for example, I get this error:

Internal error on command:"SELECT_TOOL"

If I´m now inverting one pin or just pull out the mounted extruder before startup I get the

Internal error during connect: 'ProbeEndstopWrapper' object has no attribute 'probing_move'
Error.

I really dont know what to do anymore… Even GPT Deepsearch wasnt helpful anymore.

It might be best to revert to the author of the modifications. They are likely causing the error.

3

Since there are people running this plugin without any problems, I’m still pretty sure that my config is the error. I just don’t know where to ask to be honest…

I’m pretty sure this was broken by this refactor: Refactor of probe ProbeSessionHelper into additional helpers by KevinOConnor · Pull Request #6879 · Klipper3d/klipper · GitHub

Unfortunately, the plugin is going to have to be updated for this change.

In the meantime it’s probably best to roll Klipper back to the commit before these changes were merged.

(I think I saw this in the Voron Facebook group too)
