I have just finished assembling a TT I3, with a large heated bed 220x280, a couple of weeks ago and my first print went well.
After a few initial experiments I noticed that the filament will not stick. I have manually leveled the bed over and over again, added a glass sheet over the bed, applied masking-tape and what-not.
The filament still will not stick, it will curl up on the nozzle, clog the nozzle and all sorts of other issues...
Everything functions properly but it seems like the extruder is trying to push more then the nozzle is actually putting out. My filament is 1.75 mm.
Can anyone help with all this so I can get something printed decently?
I am printing with PLA, I started off with 50 °C, raised it to 60 °C, and last time I tried to print a filament spool holder with 70 °C (twice), still if layer is thin it will not stick.
After cleaning the bed with alcohol 70%, you can see the issue in these videos:
