just assembled my MK3S two days ago and this is how the heat bed looks. I assume there were scratches and thy covered it with coating or some kind of paint. I don't really mind that it's looking like that but I am a little afraid that it might cause a shortcut due to missing isolation. I tried to contact the customer support but no-one replied yet... Anyone has experience with this? Maybe a similar looking heat-bed? I really want to start printing but haven't even switched the printer on... Every kind of help is appreciated 🙂
Thats horrible on Prusa if it showed up that way. I've seen more people recently posting about issue when their printers when they arrive, most seem to be QC (lack of) related.
From looking at the pictures it looks ok to me as long as the bed is flat in that area. If it were me I would still complain to Prusa, but I would also start using it.
The materials (PEI or Power coat) that cover the steel sheets you print on are on conductive so you should be ok.
Thank you for the fast reply 🙂
I will probably try tomorrow and let you know in case anything stupid happens 😀
Log into the online store and use chat to communicate with support. They usually only use email for follow-ups and response will be slow.
I wouldn't expect a new bed to ship like that, but I wouldn't expect any issues. My bed has worn a bit over time and I've used automotive paint (the little touchup pen style) to cover up the exposed traces. It's odd that the last pic shows raised dings without any touchup paint or marker surrounding them, but the preceding pics clearly show the dings have been flattened and touchups have been done. Personally I'd just smooth them down as much as possible, removing any raised flakes, then apply some non-conductive paint and keep on printing.
The last pic was taken at a "bad" angle... it's just reflecting the light of my table lamp. However I just couldn't wait for Prusa to reply so I started printing today. All good and good to know that worn beds can be fixed that way 🙂
