Re: Makergear M2 stops extruding after many hours midprint

If your filament drive tension is "loose" as you say, all the gear will do is chew off filament material. It needs to bite in and not slip. If you retract the filament, or observe it going into the hotend when it's running, you should see definite teeth marks when the tension is set right. Check out...

Re: PETG Pin Holes?

Thanks for the factory file! I'm a bit confused by this "Here is a link to a factory file for my calibration square which uses a Extrusion multiplier of .4 not 4.2." Do you mean width, and if so, I assume you meant ".4 not .42"? For adhesion, I've tried polyimide, glass, glass with glue stick and gl...

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 ...
