I was beginning to blame the cheap filament but it turns out that it really is all in the profile settings. However, with a necessity to get an Immortal T antenna fitted and the RunCam 5 black mounted to my quad, I was recently forced to pick this back up again because both of those items need TPU mounts.įinally I seem to have cracked it and the result is that I'm now managing to get some decent TPU prints using my budget TPU filament. So after my previous disasters with printing TPU using PrusaSlicer, I haven't attempted to print TPU since back in October last year. Not sure if that helped or just confused things more I would try and get the print to be solid first ( no voids ) and then try and deal with the stringers without changing the amount of material being extruded. in "Slicer Settings" ( if it was easy everybody would do it right ? ) So it really does come down to getting your Phd. Also see if you have a setting for "crossing open spaces" and the choices for that. The downside is it will be rubbing your part and could make it move or come off the build plate if it does not have a firm base or brim. the benefit is you won't get stringers, but you may get little blobs on the sides. This however will keep the nozzle in contact with the work even if it is not extruding. Turn off "ooze control" and lower vertical lift during retraction. It has been a long time since I used Cura and have never used Pusa's slicer. Stringers can also be caused by to much vertical lift when retracting. Which can cause under extrusion if it is not restarted in time The next issue is "stringers", a lot of times stringers are dealt with by using aggressive filament retraction. But what is the under extrusion being caused by ? I'd say the biggest issue is "under extrusion", causing voids. It looks like you have a few different issues going on there. One good thing this has proved is that there is nothing wrong with the mechanics/electronics of the printer and nothing wrong with the TPU filament I'm using. I could of course just use Cura but I've got used to PrusaSlicer and actually prefer it over Cura, so I want to try and get it working. I'm really happy with the print from the Cura G-code but it looks like I have a lot of work to try and find out what settings I need to change and/or translate across to PrusaSlicer in order to mimic what Cura is doing. I then tried translating what I thought were appropriate settings from the successful Cura slice across to PrusaSlicer and generated G-code in PrusaSlicer which I then did a print from. The results in the photos below speak for themselves. I ran up Cura 4.3 and applied the same settings in Cura as in that guys video that I linked to in my previous post, then I sliced a print of the front camera cage bumper and generated G-code from Cura and did a print. TBH, I didn't even think about doing that but it's an option. (1, 04:34 AM)voodoo614 Wrote: Have you contacted Prusa for help?
