Hi @goofycaca I’m not sure I understand your question, are you using blue painters tape that isn’t sticking to the bed, or is the filament not sticking to the blue tape, or are you not using tape at all and mean “bed” when you say “tape”? Sorry if I’m not reading it clearly.
If it is the tape that’s causing the problem, I found there’s a big difference between blue tape brands. The first one I tried was a respected brand (quite expensive) but it really didn’t work. I then found that everyone seemed to use ScotchBlue tape and it was completely different in terms of both sticking to the bed and for filament sticking to the tape. So if you’re not using this one: https://www.amazon.co.uk/dp/B00004Z4DU it might be worth giving that a try.
However, I rarely use the tape anymore since I’ve applied PEI sheets to my printers. PEI really is a wonder; for PLA it’s almost perfect - great adhesion and removal with no need for tape or glue, etc. For ABS I still find a bit of Elmers purple glue is a help for larger parts, but it’s still better than tape. It’s not cheap, but it’ll save you a bunch of time and frustration in the long run.
