Core One Bed Adhesion - Corners Warp Up  

RE: Core One Bed Adhesion - Corners Warp Up

It seems to get worse with higher fill-rates.

Any suggestions really appreciated.

Try more perimeters (4-5) and a 10-12% gyroid infill. Also, how are you cleaning the build plate?

Increasing infill will only make it worse by increasing internal stress as it's cooling. 

Please save your project, ZIP the .3MF file and attach it here. 

Thorough cleaning of the build sheet may be enough - look up threads here on the subject.

Try 'Mickey Mouse Ears'  -  helper_discs in Prusa's gallery, at the corners along with brim.

Avoid grid infill - gyroid should be OK but slow, cubic is often enough at relatively low densities.

Cheerio,

Thanks both - Apos for delaye reply - have been away but I'll try the bed cleaning and Gyroid / Cubic infill as suggested this evening.

Model is attached - any other pointers really appreciated.

I've been cleaning the plate with 70% isopropyl wipes, but will get some proper 90%+?

RE: Core One Bed Adhesion - Corners Warp Up

I like gyroid for many things and learned that you can enter any number for the density, not just the drop-down values. I very often use 7-8%. Small changes at low values can have a large effect. It doesn't trigger a reslice, so you can quickly grab a drop-down value before entering what you really want.

70% alcohol probably isn't great for removing oils and such. 91% should be easy to get. IMO, alcohol isn't effective on many contaminants so give alternate cleaning methods (detergent) a try. The 70% might be most of the issue.

Don't skip the "absorbing" step where the bed comes to full temperature. Standard profiles?
