Octoprint Cancelled Prints
Does anybody have or know of a script that will unload the filament from the MMU2 when I cancel my print from Octoprints gui, at the moment if I cancel a print it just leaves the filament in the extruder and this causes me a lot of hassle trying to get it out. 😕

Re: Octoprint Cancelled Prints
Hi Peter is there anyway to select what filament to print from when using single mode on the MMU, Once the g-code is sent through Octoprint you have to go to the printer and select the filament to load, my printer is in my garage, so a nice tweak or hack would be nice to be able to select it from inside Octoprint.
Update I have just seen one of your posts and I think that answers my question, I have edited my g-code in Ocyoprint to tell it what location to use for my filament.
