What is this ... ¿thing? recently chagne to MMU3 and it appeared on the slicer
As the title says, I just upgraded my core one with a MMU3, followed the guides and everything looks ok and working fine, the only problem is this "block" (the orange one) that appear on Prusa Slicer , it's not printed, I can move it on the bed. It's annoying because it affect the auto-center feature. Not sure what to call it or how to disable it, looked everywhere on the settings.
RE: What is this ... ¿thing? recently chagne to MMU3 and it appeared on the slicer
Its the wipe tower. You are now running a MMU so its needs somewhere to purge the filament. The printer doesnt have a 'poop shoot' or any other alternate mechanism so it needs to purge and wipe filament on every colour change. The Wipe tower is where it does that.
In PS you need to be in Advanced or expert mode and its Print Settings>Multiple Extruders>Wipe Tower

ahhh thanks, since I was printing with only one filament, I wondering why it should appear (no color changes at all). Also I thought it was always at the corner since all the examples/tests I did put it there. My mistake, much clear now. Thanks.
Then I guess it will always be there, even if there's no color change.

You can turn it off in the settings I provided a list for, just untick it.
