hello i just got a role of duramic 3d tpu 95 and printed a temp tower at 20mm/s infill, walls at 10mm/s this turned out good so I went to start the project I bought the filament for at 25 and 15 mm/s respectively and temp of 227.5 . bed plate was 60 initial layer and 55 after fan at 20% initial and…

[image] Ender 5 extruder skipping Creality Ender 5 / 5 Pro This video gives a good description on how and what to do. [Simple HOTEND FIX for Creality Ender 3, CR-10] turned out i wasnt pushing the tube all the way down and as a result it was backing up and…

added both files to dropbox above i dont understand the actual writing of gcode to know what most of it says

also it was 220 where this went bad so might want to go 230 for my next try

I have successfully printed with a modified mk8 style single gear extruder on a bowden setup, but I would also definitely recommend going to a dual gear extruder like a Bondtech BMG if you plan on doing much TPU. The bowden part shouldn’t be a problem, you just need an extruder that has a constraine…

heres a pic of the temp tower [GOPR2693] [GOPR2694]

Thanks for all this info! So we know that it can print successfully to a certain degree (no pun intended). My next troubleshooting step would usually be to try printing another model that I know for sure works well. Something like a calibration cube, try printing it with a nozzle temp of 235, we kn…

sorry new update I had another failure and looked at all the ends I had cut off and noticed a consistent bend in the filament where it had stopped at the drive wheel and bent around it not sure why it is stopping during print as when I was cleaning the print bed it went fine moving every few minutes …

I should clarify what the mods I did to the mk8 extruder were to print TPU successfully with it. I went on yeggi, and found a printable main body that had a place to insert a short ptfe tube cut to fit in between the drive gear and the output side of the main body to make a more constrained filament…

I found that when I was printing TPU and TPE, I had to raise the bed temperature, for at least the first couple of layers. It seemed that the cold bed was cooling the filament out of the nozzle too quickly, and causing a jam. This happened more on prints that had a large area on the bed, while oth…

Hi there! Its too bad to hear that this is still causing so many problems. One thing that I would like to ask about it what your retractions are set to in your slicer. Because of tpu’s flexibility retractions can be tricky. Think of it as trying to push and pull a piece of wet spaghetti through a t…

ok I had read that one is supposed to set a higher retraction setting for tpu, will try one with less retraction the pla cube came out good but it didnt print the tpu, noticed that on all the pieces i cut off that their is a bend where it stoped on the drive wheel retracts but wont advance [GOPR2…
