How to print PA12 CF15 (Nylon12) on K1

Flagship K Series Creality Flagship K1 & K1C
1

I’m using this filament for the first time:

I cannot get the filament to stick to the stock bed even with glue applied - it does not stick at all!? I just end up with a bunch of spaghetti moving around the bed with the nozzle.
I had to create a new Creality Print filament profile with these settings:
Nozzle Max: 240
Nozzle Min: 200
Chamber temp: 70
Nozzle first layer: 230
Nozzle other layers: 220
Bed temp- Smooth PEI plate (Stock plate)
First layer: 90
Other layers: 80
No cooling for the first 3 layers
Min fan speed: 30
Max fan speed: 60

CP settings:
Layer height: 0.2mm
First layer height: 0.3mm
First layer speed:
First layer: 50 mm/s

All other speeds set to 50 mm/s

K1 is about 3 months old.
CP is version 5.1.4
Model is: #3DBenchy - The jolly 3D printing torture-test by CreativeTools.se by CreativeTools - Thingiverse

Nano Polymer by Visionminer works great, I haven’t tried it with your type of filament but a sample bottle is only $5USD.

I use it on all my printers build plates.
For ASA & ABS you have to let it cool down before removing the print else you will rip off the lower layers with them still attached to the bed plate. Made that mistake once.

Not tried Nano polymer, if I use gluestick it is from Tesco (not available in the US I guess), dirt cheap. Not printed PA12 yet but no problems with ABS.

Visionminer Nano polymer is high-end stuff. If your nozzle temp is below 300, you let the build plate cool down before removing it, but if it is 300 and above, you remove it when it is hot.

If you looked at my mistake photo, which was an ASA print, I have printed many things with ASA that were very hard to break apart at the layer lines.
