Long ABS print, large surface, may have damaged surface PEI sheet
Similar to this, https://shop.prusa3d.com/forum/hardware-firmware-and-software-help-f64/pei-powder-coating-damaged--t19062.html#p88895
But much more noticeable ?
After a 12 hour ABS print, with large footprints.
Smooth surface PEI sheet, have some mark exact matching the ABS footprints. Where the ABS has warped and lifted a little of the bed, looks like the tense of the ABS may have damaged the smooth PEI Sheet. I can feel the noticeable bump no on the shert.
First timing with a long ABS print, all other prints have been PLA.

Any advice ?
* Do not print large ABS
* Only short (timesie) prints ABS ?
* Although big bubbles - ignore them for now they will go way

Hello
I had exactly the same experience this WE.
Large ABS footprint left small bubbles and also seemed to have difformed the sheet. You can feel slight variations on the surface.
Questions:
- Does anyone know if we should avoid large print with ABS on those sheets?
- Do the coarse PEI coated sheets perform better?
Thanks,
Thomas

Some bubble still there after 6 months

Some will go away, and some will stay. Print beds do not last forever; they are expendable.

Yep. Sometimes bubbles will stick around. ABS tends to be bad for many buildsheets due to it's requirement for high adhesion, and high warp tendency. Try Printbite+ or Filaprint if printing lots of ABS type materials.
