Heater block covered in molten filament. What to do now?

Hey guys,

I just got my first MINI+ and my first long print completely failed. 

I wanted to print a ~10cm tall desk bin for all the filament waste etc. in the future.I watched the first layer and half an hour later or so I checked on the print with nothing to see so I thought ok it will probably work.After a few hours of work I checked on it again and the outcome is seen on the pictures.The heater block is covered in filament I guess. Is there any way to fix this or do I need replacement parts?

Hope it's not as bad as it looks 🙁

Thanks in advance!
Luke

I think I had the Z-axis way too high and I could clean the heater block fortunately. I don't think anything broke.

Printed something else after that mess and learned something from it 🙂

Have a nice day, this is solved I guess.

I heat them up and use a stiff nylon tooth brush to clean off the molten filament.

Oh yes, the Flying Spaghetti Monster.  😉

If you don't mind, I'm taking the liberty of adding your photo to the 3d Print Blob Of Doom Gallery, which is on line here:

This shows quite a few interesting and spectacular 3d print failures.

You are lucky in that you got mostly a spaghetti monster and not a blob of doom.  I do see that you have a small blob there, and it probably just fell off before it could do any damage.

If you look at the Blob Of Doom page you will see photos from some who are not that lucky, as they have blobs which grew and grew for hours and damaged the extruder plastic parts.  A failed print during an overnight run can cause that to happen.

Yes I realized that, fortunately it's not as bad 🙂

I'm fortunate that I never had a REALLY ugly one, but I do admit that I have left prints unattended at times and come back to find potentially serious failures.

The one below is about as close as I ever got to damaging the Pinda mount.  Fortunately it fell right off when heated up.

Wow that looks really scary. I would have been in full panic mode.

That's about the closest I've ever been to a nasty blob.  It's really the end of the partially-printed piece that's over by the Pinda.  Most of the plastic is in tbe blob by the nozzle.

I heated it up to ABS temperature and waited for the heat to penetrate, thinking that I would come back and gently pry it off.  When I got back it had fallen off and everything, including the fan shroud (which is PC Blend) was intact.

All it took was a superficial cleaning.
