Unrecoverable Errors - the Bane of My Printing!
There's one issue that has me thinking, "I need to scrap the MMU and bypass it because more prints fail with it than work." It's the inability to do ANYTHING other than retry when I get an error. Right now I have this:
When I didn't have the MMU, if there was an issue with the filament feeding through, there were times I could leave the print head in place and fix it. It might be the filament broke, so there's some in the extruder (happens sometimes in this super-humid climate), or something else. Then I could go back to OctoPrint and resume the print. Now? I can retry. Oh, that didn't work. So I can retry. Can I cancel? No. Can I reset the filaments in my MMU3 by going to a load or eject filament menu? No.
The FINDA didn't trigger and it's unlikely to trigger when I retry it UNLESS I can eject then load the filament again.
MY ONLY CHOICE IS TO REBOOT THE PRINTER.
I discussed this a few times with tech support when fixing an issue with the original MMU3 setup. Apparently the devs were not sure just what else they could do. Well, letting me get control of my printer WITHOUT REBOOTING would be nice.
Just, at least, give us a choice of RETRY or CANCEL for starters. Then, as time allows, add options like letting us call the eject/load functions, then returning, for the functions that could be from issues with filaments in the MMU would help. But first, please, let us at least cancel. Then we might be able to save a print that went on for a few hours before the error than having to just redo it all.
My experience with Prusa, pre-MMU3, has been, "It just works." The hardware and software was all designed to make printing easy and to make things work well. This is what I'd call a UI design failure, and, compared to everything else Prusa does, is just far less than I'd expect from a Prusa printer.
