Build Plate damage?

Is this damage anything to worry about? Is it normal after three prints?

It's common to get a small amount of bubbling, especially with a new build sheet, when printing larger parts that are trying to warp...  The usual advice is to turn the sheet over and use that for a while or to position the next few prints to avoid the spot; the bubbles will usually self heal after a few print cycles without repeating the stress.

But you have a worse than usual example, it probably will still self heal, I wonder what's causing it.

What filaent are you printing and how are you maintaining/preparing the print sheet?

Cheerio,

Looking at that, I wonder if you have been printing PETG on the smooth plate.

It's the new sheet that came with the new machine, I have printed 3 things using the PLA that also came with the machine. I used the isopropol wipe that came with the printer to prepare it and the printed scraper to remove any debris.

If you are able, grab a satin powder coated sheet and a textured sheet. They are a great addition to the Mk4. I haven't touched my smooth sheet since I acquired these 2.

I will add them to my order. I have lights in my basket and much more filament!

I reads like a still soft new sheet and good adhesion combined with a large part liable to warp.  As @jp-guitars suggested, printing PETG directly on that sheet might cause damage, window cleaner or diluted gluestick would be needed to reduce adhesion enough for PETG or flexibles to be printed safely.

Look up some of the many threads on here about bed cleaning and first layer adhesion.

Cheerio,

So should I flip it over and rest this side for a bit? I have lots of isopropyl for cleaning. I have a big part to print, that will max out the plate. It’s for a coffee machine drip tray, I have PLA(though probably not enough) a new roll of ABS and PETG, both of which I’ve never used. Any advice? I printed something today and off set it so it wasn’t in the same spot. Prusa should perhaps have something in slicer to move items around the sheet maybe?

Sensible.

I have lots of isopropyl for cleaning.

Also look up threads about dishwashing detergent.

a new roll of ABS

Make your first ABS print very small - the fumes may surprise you, most people use an enclosure and ventilate it outside.

something in slicer to move items around the sheet

You can click and drag the previews around the sheet to taste.
