Hello everyone, I’m using Orca Slicer 2.3.2 and I’ve just discovered what seems to be a bug, unless it’s my own mistake! When selecting the filament for my U1, I choose, for example, filament 4, which is yellow, I slice my piece, and save it to a USB drive. When the U1 reads the file, it uses filament 3, which is my green spool, and that’s what the machine’s screen indicates; it doesn’t accept spool 4. I have to manually change the filament on the screen. Has anyone else experienced this problem, or is it just me? I think it’s specific to this version; I don’t recall having this problem with other versions. Thanks for your help. Stéphane
Have you tried it in Snorca instead of just Orca? Not sure who is updating Orca so things may not be the same as Snapmaker Orca. Not a solution, but an optional test.
Thank you for your reply. It’s the same issue in Snorca: when I use the right mouse button to select coil 4, everything works fine—the part changes to the correct color, I cut properly, but when reading the USB key, coil 3 is used instead. I don’t understand where this new problem is coming from, as I hadn’t encountered it until now. I reinstalled both Orca and Snaporca software, but the same issue persists. Should I re-download the machine’s firmware? Or is there a setting in the software? I’m not sure what else to do. Thank you for your responses.
OK. One last hail mary…put an previous firmware on the U1 and reboot. Then put on the current firmware again and reboot. PITA but maybe it got some file “wires” crossed??? Doubt it works cuz not sure it’s a printer thing and rather a software/PC thing but might be worth a shot. ?
Thanks for your feedback. I downgraded the firmware to an older version, but it didn’t help! However, I did something crazy: I swapped the yellow coil from slot 4 to slot 3, and the green one from slot 3 to slot 4. So now I have the yellow coil in slot 3 and the green one in slot 4. Well, the weird thing is that when I try to print with the yellow coil in slot 3, slot 4 gets selected instead!
Still the same issue: if I assign heads 1, 2, and 4 in Orca or SnapOrca, the printer uses those heads correctly. However, if I assign head 3, it systematically uses head 4 instead! I can’t figure out why, even though the G-code correctly points to head 3!
All good, I found the cause of my problem! It’s the “Auto Mapping Filament” option that needs to be disabled. Apparently, moving my yellow filament spool from Tool 4 to Tool 3 was causing the issue. After disabling this function, the problem is now resolved.
