I was talking with them last week about stock for the white and black. He has a shipment due in 6/24 and it should be in stock after that.

Thanks all for the trial and success. Your effort and contribution are greatly appreciated.
As the opaque version is kind of new, ESUN is a bit conservative and will let this small batch run several more months and check feedbacks before considering next plan. So I don't get a lot in June but will be enough for people on this forum. You all are very helpful in driving the adoption of petg and it does take time/effort for more folks to start to use this. If you have special projects and need many petg black/white, you can let me know. Thanks, /Will

I printed out my new design for an electronics box for the Smoothieboard in black PETg; it looks fantastic! I thought that the Smoothieboard should be able to handle better than the 70mm/s rate that I had from Jim's PETg setup for S3D, so I upped it to 100mm/s. I got a near-perfect print out of it. Like others have noted, very little stringing. I did get some warping, so this stuff does shrink, but it was tolerable.

I have had two jams with this stuff, though. I'm not sure if I should be dialing back on the speed a bit, or if I should be raising the temperature a bit, or if it might be caused by the Smoothieboard, because I haven't gotten around to resolving the temperature stability. I've got way too many uncontrolled variables here. The first jam I noticed right away, and pulled the filament out, put it back in, and kept going. The second time, I didn't find out it had jammed until about an hour afterward. I had to disassemble the whole extruder mount to get the jam out. I haven't had the time to try to print anything since then (was just earlier this evening), but I did run the filament back through, and it was acting strangely, like not flowing for a second after running the extruder motor, and then suddenly starting, and then continuing to extrude for several seconds after the motor stopped, just under its own pressure. I guess it didn't like being baked in the nozzle for an hour! I'll try some cleaning filament, and if that doesn't help, I guess I'll be soaking the nozzle in methylene chloride or something.

i can almost bet your running too fast for the hotend. it just cant melt the plastic fast enough. i can hit that limit with the e3d at 4000mm/min and a .6mm nozzle. the extruder gear is spinning crazy fast. it just cant pump it out that quick. back pressure takes over and it jams. the newer hotends like the v4 and e3d have short hotzones making it worse. i guess thats why e3d made the volcano setup.

The fastest extrusion I ever managed was from a modded MG V3 classic. 160mm/sec extrusion on PLA @ 0.5mm layers

It was E3D volcano territory, 3 years ago!

Well, I ran a second time at 70mm/s, and it jammed up at more or less the same place. Noting that the jam occurred twice within a minute or so after starting the first infill layer, I looked at my infill parameters, and decided that maybe the problem is having the infill extrusion width set to 140%. I think that's too much, although it was working great for the translucent PETg filaments. I am running again with the infill extrusion width set to 100%, and I'll see how that goes.

But did you see my post on the "Smoothie M2" thread? I set it to 200mm/s on PLA (0.2mm layers with a 0.35mm nozzle), and it gave me a decent print; a bit sloppy with the details, but passable.

That's a lot of plastic to push through a 0.35mm nozzle ... willing to try it again at 0.1mm with everything else the same?

pla also melts really quick and gets liquidy. at 70mm/sec with 140 infill through a .35 nozzle is just too fast. the back pressure is too great. drop that infill width to 120 and .2mm height and drop the speed down to 60mm/sec. i am using the exact same setting with the black that i was with the translucent. there really isnt any need to change anything.....that i have found anyway. stuff seems to print the same.
