What is going on...
Hello all,
Only been doing this for about 2 weeks so need advice. I've got about 20 prints in with PLA that came with my Prusa and wanted to give ABS a shot. Did one print today in white but noticed some darker spots, also something leaking on bed. Can you tell me from pic what is leaking out and how?
Thanks
Re: What is going on...
I wonder if it is grease or oil from the bearings. There is a lot of it on the outside of the bearing in your picture.
Re: What is going on...
Dark flakes after switching from PLA to white ABS could be left over PLA that got burnt at ABS temps or simply the usual debris that does accumulate in the nozzle. Cold pulls usually help to fix or avoid that.
I am not sure i am seeing this right, but it looks to me as if you got some grey goo sticking on top of the heater block.
Here for example:
Is this grey filament that came with the printer? There's no reason for anything to be on top there, it should be spiffy clean. Did you have one of the printing oopsies where the hotend ended up encasing itself in a ball? Or is it leaking? If leaking, the most likely place it oozes out from is the heatbreak threads,
i.e. the hotend wasn't assembled right or it got lose when swapping nozzles or somesuch.
I guess what i would do now is to clean the heater block best you can, then print something and keep an eye out for oozing in this area. If it starts up again, you are going to have to take the hotend apart and reassemble while taking extra care that the heatbreak is screwed in tight (and also check that the PTFE tube isn't frayed and seated tightly against the heatbreak).

I believe it was an oopsie and some got on top. And yes was grey filament that came with
So that space on the hotend should not be there? I will clean best i can today and try again
Re: What is going on...
Not sure what space you mean. But there should be no filament on the top of the heater block. If it got there during a failed print, no biggie. If it keeps coming back, we need to figure out where it is coming from.

The pic that you had the "1" "2" numbered. I guess i didnt understand what you meant by not assembled correct
Re: What is going on...
And is acetone what i should be cleaning with?
Re: What is going on...
1 and 2 in my pictures mark where molten filament might ooze out because the hotend wasn't screwed together tight enough. Sorry, I should've made it more clear

Ok thanks. I should probably just take apart and re-assemble correct and clean best i can

Just heat up to PLA temp and see if you can scrape it off. Its just so we can see if more comes out later.
(Be careful around the open wires there at the side, you don't want to short-circuit these.)
Ok thanks. I should probably just take apart and re-assemble correct
Wait and see if if it is really oozing out there. No need to go through this if it isnt leaking there.

Ok thanks for advice. What should i clean up the ooz and old filament with?

Sounds good, thanks
Re: What is going on...
Seems was old pla from a bad print that was leaking down. I cleaned and no issues with oozing since. However having other issues looking into now. Will post new if need some assistance.
Thanks
