Problem with printbed after my 5 print 🙁
Hey Guys. i have done my first 20h print. It was print number five.
Hotend 200c
Bed 55c
and after the print i remove my print and found this!
The blue marks are my fail but i mean the red mark.
the first layer was a support Line after that the print starts.
Looks like the PEI burned???
Someone have a idea?

I get that too, I'm fairly certain it's normal as the previous mark disappears with each successive print.

When I got that with my first big print I was a bit upset too. It goes away.

Really? I hope so. I bought a new sheet and will replace the broken one.

If you look very closely or with a magnifying glass, you'll see those marks are actually tiny bubbles trapped inside the adhesive layer the holds the PEI sheet to the heat bed.
In time they will disappear (probably re-absorbed into the adhesive)... Until next print 🙂
Apparently they cause no hill effect to prints, but they may be a sign of eccessive first layer squishing.
Was your printed part hard to remove from the bed?

The print wasn't hard to remove. It was a tiger tank which has printed the first layer as support to a high of 0,2mm there was only a little thing what lays on the bed from the print. The rest was support. I picked It up witch my fingers and a plastic spatula.

Ah... I can see the tank outline now 🙂
If you had no trouble removing the print, then I'd say there' is nothing to worry about.
If you can, let the bed recover between prints (24 h would be best IMO).
