Getting the 1st layer to stick... again. [SOLVED]

I know this has been mentioned many times before, but looking for new advice. If I get past my first layer things are aweseom, but getting past the first layer can be really challenging, especially on certain parts.

If I do infill 1st, the problem is worse because the frequent back and forth balls up easier than a straight line.

Painters Tape works for me sometimes, scoring it with a razor or sanding it seems to help, but Kapton tape definitely works better, and without manipulation.

In the past I've had prints that took a LOT of force to remove them from the print bed, lately they can be flicked off.

I've tried laying down the 1st ayer at 185 and 190 c

I lay down the 1st layer really slow already.

Any other suggestions? I'm going to try a higher temp and see if it helps.

I do have a heated bed I've been procrastinating on, would that help as well?

I guess I posted too soon... upped the first layer to 200c and it sticks really well.

I've been using the same roll of PET tape for about half a year or so ..and it works better than kapton tape IMHO .. the green PET tape

I am having other issues at the moment, but see the pic... the nozzle drug through some of my poor 1/4 inch kapton strips so I ripped them upo and printed anyways. You can see how where the kapton wasnt at it definitely made a difference in how well is stuck, I have repeated this experiment many times over during the same prints to have as good of a comparison as possible... might be good to do with other tapes as well.
