I sliced a multimaterial print and after laying down the first layer of the tower snorca generated a wild move way off the bed and back. I hadn’t noticed this initially and so had started the print. The printer, of course, threw an anomaly error for a bad xy move. The tower was rib style. Changed it to cone and it worked fine. Is this a known issue with the current release?
While on the subject of the slicer, is there some way to control the bed temperature reliably when multiple materials have different bed temp preferences. It seems that snorca simply uses the bed temp for the first filament that it decides to use at the start of the print. That is annoying if I’m using PLA as a support for PETG and the slicer picks up the PLA first, thus setting a low bed temp that PETG isn’t that happy with.
Yes, if they are actually part of the model. But if you are using PLA support for PETG, the slicer starts with the support material which being PLA sets a lower bed temp. The only way I have found to avoid it, is to temporarily set the PLA profile to the higher bed temp. But that seems like a poor way to accomplish the goal. It seems that the multimaterial model in Orca is slightly broken since it wants to blindly pick the temp from one of the filaments, whereas in reality the bed temp for a multi-filament print is a global property that should have some way to set explicitly. It can default to the filament one if all the filaments in use have the same temp but if not, it should ask the user (at least optionally).
From my perspective, if the first layer contains both PLA and PETG, switching bed temperatures between them is pointless—just use the higher bed temp throughout. When you switch from PLA to PETG, your PLA will still be exposed to the PETG bed temperature anyway.
I agree. I don’t want to change bed temp; I just want the slicer to pick the right temp which in this case would be the higher temp that PETG needs. As it seems to work, because the first filament the slicer chooses to print is support, which is PLA, it uses the lower temp. There doesn’t seem to be a way, other than editing the PLA profile, to get the higher temp. This seems like a mistake by the slicer.
To the original question of the xy move with Rib Tower, I have seen this reported frequently in Snorca 2.2.1. I reported it directly to Snapmaker via other channels.
@Simon_Zhi it is a pretty common issue. One user reports that turning off Fillet for the Rib Tower settings made it go away. Many users report needing to use a different type of tower (cone or rectangle).
I haven’t had the U1 long enough to do anything more than the test print, but I ran into a similar problem using PLA supports for a PETG print when I first got my H2D last year. The fix/workaround there was to use PLA for the support interface only, so everything but the top 2 layers of the support tower get printed in PETG. That’s got the added benefit of fewer tool changes, which translates to a shorter print time.
