PETG Speed vs Quality and beyond
I've recently got my machine (a stock Tevo Nereus) tuned in quite good with a generic petg.
Quality aside, i've got in my opinion great results with petg.
This filament, Clas Ohlson universal PETG, i run at 235 with 65c bed.
4mm window glass on stock alu heated bed. Lots of gluestick and i really jam the first layer in there.
According to PS on 0.4nozzle with 0.6 wide extrusion and 60mm/s i'm running around 9ish volumetric thruput.
A 0.6nozzle with 0.6 wide at 60mm/s show around the same 9ish vol met thruput.
A 0.6nozzle with 0.8 wide at 60mm/s get capped at 12mm/2.
I dont think i should push the speed higher with the large glassbed.
I have considered a 0.5 or 0.6 nozzle, but then i think i would loose out on the smaller objects i sometimes do?
Like the clips below, the curved arch is 2mm wide.
As far as i can tell, i don't have any over or underextrusions (most of the time anyways).
The little blobs are when the nozzle sheds whenever it accumulates.
Any thoughs or other inputs i'd appreciate it.

RE: PETG Speed vs Quality and beyond
A bigger nozzle will let you push a lot more filament at slower speeds, so is good for your concerns about the weight of the bed. For functional parts, 0.6mm is a good middle ground. Obviously, big printers aren't idea for printing miniatures.

Yeah it's kinda where my thought are leaning.
It's a standard mk8 hotend on these ones, and a closer inspection of the heaterblock it begs me to get a siliconesock as well.
This is the only machine i have set up for petg, i don't quite trust my flsun QQs with petg, and i rarely do so small clips, this is for a ropeligt where the originals i printed in PLA now start to break at the screwhole.
Thanks for your input.
