Re: PETG Pin Holes?

It's an M2E, with a 0.35 mm nozzle. I've used Hatchbox white & black PETG successfully in the past, using Jules's detailed notes on PETG printer settings. This stuff behaves a bit different from the Hatchbox filaments. I'm re-running the 240C temperature test. First attempt lost bed adhesion, so I m...

Re: PETG Pin Holes?

Thanks! I had layer adhesion issues, and cranked it up early on, but I was in the process of backing off the temperature without cooling when I spotted the pinholes.

I'll try 250 & 245 and report back.

PETG Pin Holes?

I'm trying to dial in the settings for a new spool of eSun red PETG. I've run some single wall calibration cubes, and I'm getting tiny pin holes in the walls. This is in the middle of walls well away from the starting point, so it doesn't have anything to do with retraction, coasting, wiping, etc. I...

Re: Avoiding Hairballs with PETG?

I've switched to printing with PETG, where the fine stringing will make the hairball issue much worse. I tried using the M109 "wait until the extruder cools down to 50C" command, and it didn't work as I had expected. Here's my present ending script with the new command inserted after the 10mm lift c...

Re: Run Out of "Knobs" to Turn

The parts will get whacked a bit in use, which is why I want them to be sturdy. I'm hoping the PLA+ won't be as brittle as straight PLA, but I may eventually have to try another material. In any event, I applied several of the suggestions. I dropped the infil down to 80% from 100%, and it changed th...

Re: Run Out of "Knobs" to Turn

Have you tried to print 2 or more at once? That almost looks like too much heat as the nozzle is always close .. found this to be an issue when printing some really small miniatures .. Can you post the SLT? I have the .5 nozzle on the M2 atm and won't change it for a few days (have to print some Ni...

Re: Run Out of "Knobs" to Turn

layer change is combined with going back & forth Preview the infill pattern through that section: I suspect a difference directly inside those "defects" which changes the structure just enough to affect the perimeter threads. If so, perhaps picking a different infill pattern might shake the dice en...

Re: Run Out of "Knobs" to Turn

the grove is the Z axis change to the next layer. ... Actually, it isn't just the layer change. The layer change groove/line I'm used to, but there is a much larger defect when the layer change is combined with going back & forth to the support section: eSun PLA+ Grooves.jpg As Ed pointed out, the ...

Re: Run Out of "Knobs" to Turn

The parts are small, and I need to make dozens of them. Messing with two piece designs isn't worth the bother. Same for coating them. They will be fine as is, but if I can make them less prone to collection grunge with a simple tweak to the process, I'm curious to find out what I can do. I've done s...

Re: Run Out of "Knobs" to Turn

The model is chopped off to speed up test prints. It's vaguely symmetric, and if I invert it, the section above where stopped the test prints will just do more of the same. The overall print is usable, but the groove left in the part will collect grime and be hard to clean. I'm mostly trying to lear...
