Badly fouled print head


I have been having problems with getting my blue Prusament PLA to adhere to my textured bed. I thought I got it, but apparently not. Last night, I left a print going before going to sleep, and this morning, I woke up to this. 

I've tried prying it off with a set of pliers, and that didn't go great. I was afraid of torquing hard enough to screw with the y-axis. 

How would you recommend I get this PLA off of the print head? Will I have to disassemble the printer? 

Also, any thoughts on why I am having such a hard time with Prusament PLA on the textured surface? I couldn't get _anything_ to adhere to it until I sanded it a little bit. Do I need to swap for a smoother textured print plate?

Preheat and select next material hotter than PLA. This will soften it so you can gently pull it away.

Also, the textured sheet isn't good for PL.
For PL, it's better to use either the smooth or the satin sheet.

Thanks everyone, 


Sylvia, I was able to heat it up enough to get the majority of the gunk out. That was a good idea, thanks! 


Xanthe, really interesting, thanks! I wish that had been made more apparent when I picked the options. I've ordered the satin sheet, so hopefully it will arrive before too long. 

I appreciate the help - this forum is great!

RE: Badly fouled print head

I had the same ‘PLA not sticking to the textured plate’ issue when I first built my printer this past July. If you search around the forums you’ll find this is a common problem. 

Before discovering this forum I bought a roll of PETG and found it to stick far better to the textured build plate. I learned how to properly clean and care for the build plate(s) in these pages and eventually got PLA to stick as well. However I did buy a satin sheet which is what I now use for PLA prints.

Search around, there’s tons of great info in these pages!

Good luck!
