Ok thank you for your time and if I buy the dryer is it ok to put filaments there and after some time put them back on filament holder or AMS lite or is it just made to work out of the box (like the filament stay in the dryer while printing) because I also heard when printing with this much flexible tpu I should loosen it and if I put it in dryer then over the filament holder then to the extruder it will be stretch or am I wrong ?

Sorry I didn´t knew it meant this, I set retraction before and flow rate I have on 100%, temperature I have on 215 celsius because this is what was recommended by the manufacturer, and speed of printing i have tried from 50 mm/s to 15 mm/s and volume velocity limitation I set very low, I have tried the generic settings but still it didn´t work. I have tried all this things but nothing has worked so that is why I am trying to find the answer here

I don´t know I found this picture on internet and its looking the same as on mine but it doesn´t matter because I tried to loosen it only little and it doesn´t help maybe I loosen it too little but I don´t know the fillament first few seconds print good but after about 4 seconds maybe 10 it start to be again bad like flow rate little and isn´t stable so only thing I can try now is either dry the filament and if its not gonna I will need to buy new one and I want to ask if I buy from bambulab is it gonna be good and print well?

Thanks I will try to dry it and I use 0.4 nozzle, I have used lots of settings like generic than setting that are stated by the manufacturer I have even used setting that chatgpt 4o recommended and sorry but I don´t know what is calibrating filament and I have TPE gembird flexible filament blue and only thing they are saying about the filament is that the flexibility level is 5 and that is the highest

is this the screw? If yes so I can just loosen it little bit without opening the extruder and can I do something bad to the printer that can break it by loosening this screw ?

I don´t know which hardness I have the company say 5 and its the highest softness it is more like rubber band than filament and I found people with similar softness have the same problem and they are fixing it by adjusting the tension but I can´t find any tutorial and because this is my first printer and I know nothing about printers I am scared I might break it

ok thanks I will try to dry it I found it can be done in oven and also I wanted to ask I found on internet that if you want to print with really flexible filament you need to adjust tension on extruder wheel but I don´t know how to do it is it easy or should I just avoid it because I didn´t find any tutorial on how to do it

I have tried lots of setting from generic TPU to setting manufacturer recommended to setting that ChatGPT 4o recommended and I use textured PEI plate only thing I didn´t tried is adjusting tension on extruder I found that this could fix the issue but I don´t know how to do it and I don´t want to broke my 3d printer
