Re: burned(?) PETG in prints

just using them as they were The guy who gave me the idea made a positive duplicate of the nozzle, created a negative mold of a boot surrounding it, then cast silicone rubber into the mold to make the boot. I liked the silicone boot idea, but all the mold-making & casting seemed like way too much w...

Re: burned(?) PETG in prints

What do you think is causing this? The other end of each fine hair you see on your PETG objects melts back onto the nozzle, accumulates into an oxidized blob, and eventually smears onto whatever's underneath, usually in the most conspicuous location. Minimizing the hairs by getting retraction dead-...

derived the original 1007.7 steps per mm
Betcha the 3.17555 mm pitch is really 3.1750 mm = 1/8 inch pitch = 8 TPI, which gives 1007.9 step/mm with a 1:16 microstep motor.

If the US-of-A had gone metric, back in the day, we wouldn't even have 1/8 inch leadscrews to kick around …

Re: strange print

what do you mean in "bar width " The figures appear to be the capital letter A, made of two long and two short bars, each with a gap between two single threads. I assumed the bars are 1 mm wide. If that's correct, then the problem is as I described: the slicer cannot produce a solid 1 mm bar from t...

Re: strange print

a simple 1 mm square part consist from 4 cubes I'm not sure what that means. A "1 mm square part" is at the very limit of what's printable with an ordinary 0.35 mm nozzle and 0.40 mm thread widths. If the bars in the "A" shapes should be filled in, then it looks like there's not enough space betwee...

Re: Horizontal axis inaccurate - M3 SE

switch it over to automatic and let S3D calculate that as it needs Yup, the whole point of the Extrusion Multiplier dance is to match the actual amount of extruded plastic to the expected amount. With that set up, when the slicer calls for 1 mm³ of plastic, the extruder delivers exactly 1 mm³. The ...

Re: Run Out of "Knobs" to Turn

better results on some models at ~ 80%. Absolutely! Building a solid block of plastic from threads requires perfect settings, which straight-up can't happen over the entire part: the physics changes as the cross-section changes. Even a "solid" part has internal voids, so it's not going to be waterp...

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...
