X1C Combo + Cold plate = Lots of problems getting PLA prints to stick to the bed

Pretty much what the title says... not sure what I'm doing wrong so totally open to ideas.

I come from a Prusa MK3 and never had issues with PLA sticking to the plate before. I got my X1C a couple days ago and while I have had a few successful prints I'm getting a lot of failures for just first layer not sticking. This is specially so with models that have a lot of small parts like the torture toaster.

So far I've tried with the green PLA sample that comes with the printer, SUNLU PLA+ and Prusament PLA. For the last two I'm using the Generic PLA preset. Using the cold plate with the printer closed and keeping the bed temperature to somewhere between 35 and 40 (did a couple tries).

For the bed I basically grabbed it the first time, put glue stick all over it and started printing. Right now I just washed it completely with detergent + warm water and I'm waiting for it to dry before starting over.

Any hints or tips I could try?. The printer has been amazing so far, just having this issue with reliability in some prints.
