Starts of printing fine then turns into candy floss

Recommended Posts

Just got my new printer and have been printing off a few bits and bobs everything was good, until the other day was printing off a larger item, left unit running over night and in the morning found the machine full of candy floss! The print was supposed to be about 200mm heigh but only got to 20mm before started misprinting.

Anyone have an idea what is going wrong? Still new so haven't changed any settings.

Thanks,

Could be lots of things but typically it's because the part fell over.  I recommend not leaving alone for more than 20 minutes until you have more successes.  You are lucky the part didn't drag around with the head and then you can get a massive ball of molten plastic.

Did you do bed at 60C?  That's recommended for good stickiness.  Also a very thin layer of that glue stick.  Wipe the glue stick on the glass, then use a wet tissue and spread it around extra thin.

Also use the Brim option.  Also make sure the bottom layer is well squished onto the glass - I can't tell from this photo but you want the very first traces to be wider than tall.  If not just rotate all 3 leveling screws by 1/4 turn CCW.  I often do this at the start of a print (fine tune leveling).

Thanks for the tips gr5!

Was using PLA and bed was default at 60 deg, was using glue but will try the wet wipe next time with the brim setting

Tried this afternoon printing again while watching and it started to candy floss but noted was not extruding properly, so think it missed a layer or 2 then was printing in thin air. Did a Atomic clean and has been fine so far.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
