I slowed it down again and here is what I got.


Thanks

I will slow it down and print another one.

I don't get in a hurry printing. It took me 3 weeks to print the last math spinner!

If so that is way too fast and could be part of the problem. PETG should never be run faster than 35mm/s or in your settings it would 2100mm/m.

You are probably stretching the strands si they are not actually in contact with each other as well as they should be. I did tell you it was a slow filament. But with little smell and the finish it gives when set right I can live with slow.

still showing some gap where the top and sides meet.
the 30mm cube when printed measures 29.69 X 29.6 and 29.66 high
looking close at the corners do I need to slow the printer down more.

Thankd
Dale

here are some pics.

what do i need to do.
I am thinking I need to set the extrusion multiplier back up to .9

and upping the infill to 30%i get no stringing

here are some pics
1st & 2nd print are at 80% complete.

added an other top layer and set the infill to 30%

this evening I will print it again.

So if you have a very small infill like 20% or less the first few layers can droop down into the openings between the infill. So you might need to increase your top layer count to cover the sagging on low infill items.

I can see little holes between extruder lines. Than being said I forgot to measure the diameter of the filament before starting.

If those few strings was all I was getting I would be happy.
