I have no problems with it at all. I print normally with 215 and 50 °C.
If the adhesion is poor, the print gap of the first layer is usually badly adjusted. Check that this is correct, or make the distance a little smaller.

Hello all
Same here.
Ender 3 v2 (210 and 50 degrees) and holds well. I always use the adhesive lacquer from the spray can. The varnish is brilliant! In contrast to the glue stick (which also holds well), it is applied more evenly and is thinner, so it doesn't leave any traces/relief on the print object. In addition, 40 degrees is already easy enough. When the print has cooled down completely, it can be lifted off without any effort.
Never heat the adhesive varnish above 50 degrees.

Don't have any experience with the Ender 3 v2, but had similar problems with adhesion on one of my printers (Vertex k8400). Interestingly, it works quite smoothly on the Anycubic without a heatbed.

I assume that Raft and Brim Skirt did not help.

Have you checked whether the distance to the pressure plate is correct?
If nothing holds at all, set a rather small distance between the nozzle and the pressure plate.
An even better solution:
You can set one slicer to over-extrude the first layer.
Change the first layer (Raft, Brim, Skirt), I assume you have already tried this and it didn't help much.


With both you have to be careful not to let material back up in the nozzle. The method works very well for me with smaller parts.

Another very good solution is glue stick (e.g. Pritt) on the pressure plate, I was sceptical at the beginning but it worked (had more problems with detaching from the plate recently). There are slightly less problems with the nozzle.

For parts with a large surface area, I would try a combination of both, as you are more likely to have problems with heat distortion (possibly with the pressure plate at a slightly higher temperature).

Maybe a lower printing speed for the first layer will help.
