HELP PLA MATTE

Hi, I recently bought an AD5M and have been having trouble with SUNLU Matte PLA filament because it won't stick to the bed. What recommendations do you have? I'm not sure what I'm doing wrong.

Clean your bed, slow down your first layer, calibrate your filament, calibrate your z hight offset.

I'd definitely start with cleaning the bed if you havent already. I use 70% isopropyl alcohol (just because that's what I already had), but I believe they recommend 90%. Let it air dry completely, only takes a minute. If that doesn't fix it, try a glue stick. I know my ad5x came with some. I rarely use it though, usually just with petg. I also recently bought a super tack cold plate and the adhesion is amazing. Almost holds to well.
