Unload after cancelled/failed prints?

[Bill_Skullman]

Hey guys!
I've got a Prusa MK3s MMU2 and am new to Octoprint although I have been printing for a couple of years now.
I'm just curious, is there a way to get octoprint to unload the filament after a print has been cancelled or fails?
Thankful for any help
Bill

The solution is part way down and works great.

Need to make Cancel Print work better for Prusa, MMU

When I discover something is wrong and I need to abort and start over, I try to Cancel Print. That leaves the printer in a bad state, with the hot nozzle touching something. I need to be quick and manually lift it using Octoprint. It also doesn't restore the setup to be ready to print reliably. It's still hot, and there's filament all the way through the MMU2 filament switch to the nozzle. I'd like to hit Cancel Print, clean the print bed, and quickly start a new print. I'm using a Prusa MK3S…

move your nozzle clear of the print. get it some z height to to make sure you not ramming your print of the bed mcdvoice.com

Hello @Carmela!

The problem is when you use the MMU2, you have to unload the start of the filament back to the MMU2 selector. So it's a bit more to do.
