Pattern on the heatbed steel sheet

Hi
Please dońt kill me but Ím totally new to this and I have done my best to try and learn Slic3r and 123d design (have actually made some designs), but Slic3r and all itś settings is still a little mystery to me.

Anyway I have now got the printer and Ím almost terrified to touch anything so that something bad will happen.
So what I have to do now is to get that bit of filament out and put new in and do the first layer calibration.

But hereś the stupid question, doesńt the pattern as you can see on the pic have to be removed?
It was a piece that said PRUSA in the middle of the pattern but it came off quite easily. But I guess the pattern have to be removed otherwise the heatbed will not be level, but I dońt want to use to much force so I break the heatbed.

So when you have stopped laughing can you tell me if I should remove it and how I´ll do it.

Thanks
Krister

Re: Pattern on the heatbed steel sheet

I'm guessing that you bought an assembled printer, rather than a kit (as I did), and that this was part of the test before shipping. The test print should have been removed before it was sent to you. Try peeling it up with a fingernail from a corner. The printbed is covered with a PEI sheet, which is a new surface to me so I am not sure what can and can't be safely used on it. I'm a bit astonished it doesn't come off easily as it should have been printed with the bed hot and then, as the bed cooled down it would have contracted a bit, loosening the plastic.

Of course, I completely forgot that the steel sheet is flexible (this is my first printer with such a thing.). Pull off the steel sheet and bend it slightly in each direction. The test print should start to come off.

I have tried that but I was afraid of breaking the sheet but I will try again.
Thanks

Re: Pattern on the heatbed steel sheet

thin prints can be difficult to pop off, as they are usually flexible.

if you have a bottle of ISOPROPYL ALCOHOL - IPA - ISOPROPANOL LIQUID dribble a few drops on the corner of the print, then
you could use the corner of the Prusa logo print, to push against the edge of the remaining outline, to skid it off the buildplate

Re: Pattern on the heatbed steel sheet

Make sure you clean your sheet after touching it.

A wash with dawn dish soap and water in the sink using a clean paper towel to dry and not touching the sheet except for the edges will help with adhesion. A wipe with Isopropyl alcohol for PLA and Windex for PETG after will get the sheet to optimal printing...

It is especially important to clean the sheet in the beginning as a lot of people experience adhesion issues at the start. there are many threads on it for reference.
