I have a weird issue that started (I think) after one of the updates. (It is a first batch unit).
In the homing sequence the U1 "realizes" that tool head two is not parked correctly (even though it visually and mechanically appears to be seated just fine as it always has been):
^("Toolhead Swapping Anomaly Error Code: 0002-0523-0001-0040)
^(Toolhead 2 detached. Manually reinstall the toolhead into its dock, then tap to attempt resuming the job.")
I tried the cleaning of the pogo pins and pads with alcohol etc. but that sadly did not help.
I can usually spam "continue" or abort and retry multiple times and after a while it starts getting further and further into the homing sequence until it finally starts printing (in the video that happens after ~halfway point.
This whole homing retry dance usually takes around 15 to 30 minutes or more.
The next print usually goes through on the first try without the issue (when leaving the printer on). After a reboot it usually needs to go through the whole retry attempts again (15-30 min of touchscreen spamming).
So it kind of still works a bit. Just not really how it should.
I will also send this to Snapmaker support I guess?
