PLA was printing almost perfect but PETG is giving me some trouble, and I have some electrical interference from a rewiring. February 23, 2017 06:42PM |

As far as PETG is concerned, you can try slowing down the print a bit (I print it at 30mm/sec max and get good results) and see if it helps. Also for small parts, PETG retains heat for a while, so you either need active cooling of the part or you need to print the small parts together with something larger. When printing small parts without cooling, I can often deform them easily by hand when the print just finishes.
All in all, PETG is a great material once you have it dialed in and has very nice mechanical properties.

I was able to keep the nozzle clean and stop the blobs by doing three things:
(1) Fine tuning the retraction, I was able to keep the nozzle clean but have messy parts by turning retraction to 0mm, but I wanted clean parts, so I slowly turned the retraction up from 0mm in 0.5mm steps, 2mm seemed to work best.
(2) Going slow seems to help, I have it set at 30mm/s, I will try to up the speed later.
(3) Printing hotter also seemed to help, I went up to 260.
(*) I also have a part cooling fan running as slow as it can.
Here are what my parts look like now:

and my nozzle after that print:

The PETG glass transition temperature is about 78C, so you may want to be careful with those parts until they cool: they'll be quite soft due to the bed heat otherwise.
