Wow! Thank you. I honestly didn't even know of all those in depth settings. Now I feel the need to do a deep dive through the documentation to get a feeling for it all. I adjusted the recommended settings and i will post the results when completed.

thanks slashee, I have a ultimaker s5 with material station, should be dry from the material station. the majority of it is printing perfect, just the starts. but maybe thats as good as it gets with TPU? I am using a .4 nozzle, which would be better? i do have a .6 CC If you see the picture i attached.. you can see the far left edge is perfect and the cura file has no starts on that edge. and the clumping does appear to only be where starts are located. cura file.3mf

Im printing in TPU and there are parts that are clumping, that are exactly where the white "starts" (line type) are. Are the "starts" where the nozzle physically starts for each layer? and is there any way to minimize that clumping and stringyness. if you see in the photos some edges of the model without white parts printed perfectly so its not a mesh issue. printed in ultimaker TPU95 @ 20mm/s speed, .100mm layer height Thank you

That looks a lot better! I don't see any through holes from the slicer. You were correct about the sharp point on the edges, I flattened them out slightly...seems to have fixed the problem. thanks 🤝

made in blender.

It is going to be printed in TPU. It actually printed really good, just a bit of sloppiness in those problem areas the model in blender looks good as far as topology and no duplicate edges or vertices. I will try to flatten the points out at the ends and see if the slicer likes that better.

ok, thanks for the reply. 🤝

here is an stl looks like the walls have enough thickness? i could be wrong though Model.stl

thanks for the reply, yea i had it in slot 2 for the longest time, i ended up having to replace the bowden tube as it was causing issues with pva. so i have just kept it in 1 since. ok that makes sense about the timeout , But why only Printcore 2 ? in the picture the PLA was fully retracted , the PVA you see never retracts further than that. its not really causing problems as it works fine, But just curious as to why one and not the other.

Im not sure if this is normal or not, it does seem strange that at the end of a print a Printcore 1 only pulls the filament out like an inch. While Printcore 2 retracts all the way back to the material station? would this have to do with printcore 1 being loaded with pva? maybe that type of filament dosent retract due to its brittleness? Thanks,' Ryan

Any Idea why the model 3/4 up has choppy & missing sections? also trying to find information on the "starts" linetype, as that seems to be where the issue is. Thanks, Ryan

You were right Geert_2! the left stepper motor bolts became sightly lose. The belt was loose and the speed was causing the teeth to skip and causing the print to shift... tightened it up and all good thanks again

what could be causing this shifting in the layers? ive never had this happen before... is this a slicer / code malfunction ? trying to find a solution, not too sure where to start though. Everything looks fine in cura preview with the print layers I’ll try to re-export the model as obj and see if anything changes

thank you!

is there a way to know what time in the print time a specific layer will be at? I am embedding a magnet at a certain layer, it is a large print and it would be nice to know the exact time i would have to be there for the pause. thanks, Ryan
