TEVO Tarantula Owners Group

Hello everybody, I am very new to this, I only have maybe a dozen successful prints ever. But I have run into a major problem that is haunting me. My filament gets fat and clogs the PFTE tube as it is entering the quick release fitting on the top of the hot end. I am printing black PLA at 209 degrees. I would love to hear any ideas. Thank you so much!

im printing with PLA on a blue tape and after some time the print starts warping and lifting the tape. what to do?
(im useing cooling fan, bed temp- 25)
and i have to print on the blue tape because i have hols in the print bed

I've already tried everything that the online community tells me to do to solve this problem, but that all doesn't help me. Almost everyone is saying that i just have to swap these lines of code and it will work, but it's not working. Any ideas ?

By the way E0 is not working because i've burnt a pot on it :)

Last time I created an stl file from an object I designed on Solidworks, then I produced a gcode file with Cura, the printer just stopped about 66% through the printing and the nozzle stayed where it stopped without even going back home as it always does.
Consecutive stl files I created for other objects on Solidworks and converted to gcode with Cura did not even start printing (nor doing the initial operations like heating the bed and nozzle).
Then I took an stl file which I created with Solidworks in the past prior to the time the problem started, converted it to gcode with Cura and it was fine.
So it seems like something has changed in the way Solidworks creates the stl files. I can't figure out what it is.
Don't know about any gcode debugger either that I can use to see where the problem is.
Any thoughts?
Thanks
