Need help printing with Nylon

Hello All

I have some 1.75mm Alchement brand Nylon filament and want to print some parts for a new printer I am building and am having some issues. I am printing on Kapton tape, 225c extruder temp, tried heated 80c-110c and unheated bed, fan 35%-100% and no fan and can't find what should work.
The print seems to start off fine, (a little stringing on moves, don't know if that's normal or not), after about 3 or 4 layers the edges start curling up and the whole print then just breaks loose. Any heat settings I've tried results are the same...

Someone who has experience with Nylon please help.

Thanks

I had some success printing on blue tape with nylon. It was still a bit hit'n'miss for sticking to the bed but the best I found. I was using weed-whacker nylon and printing at about 250c, so things might be different with a proper filament intended for printing rather than cutting grass

I'm printing on glass with hair spray, a layer of glue stick, and no bed heat. Also helps to print with a 2-5mm brim.
