I'm using Prusa now, due to this one issue. My MG2E is stock, with the factory firmware. The printed extruder housing does wear over time, but I've printed spares. The next time I replace one, I think I will drill it out and install a brass sleeve where the filament wears. I've actually been very pl...

Just for completeness, here is my final factory file that was used to print the gap models in the previous post. Both are based on my "DGP" (Doug's Gapless Process). The first model is set up with ERD=0, and has no gaps. The second model is the same, only ERD = -0.07. Gap Test DGP + -r07 E...

Well, there's more to the story. Once I went back to a larger version of my model, I discovered that without a small negative Extra Restart Distance (ERD), I was getting "zits" on the faces of some dovetails I'm using to built a larger overall structure. I could clean them up by hand, but ...

After lots of experiments, I think I have things pinned down. The gaps were the the result of a combination of settings. The biggest contributor was the Default Speed, followed by Extra Restart Distance, with a tiny effect from the Minimum Infil Length. In the course of chasing this all down, I disc...

I ran another set of tests with just the Extra Restart Distance and Z-Lift parameters in play. Both state with Airscapes's gapless process, but with a single parameter change to the values from my process that creates gaps. Test 3A: ERD changed to -0.05 Test 3A.jpg There is a single tiny gap that yo...

More test results, and things are beginning to get interesting... Test 2A was Airscapes's gapless process, with three settings imported from my gappy process: extraRestartDistance = -0.05 retractionZLift = 0.2 retractionSpeed = 2400 Test 2A.jpg There is one section of the inner perimeters that shows...

Curiosity got the better of me, and I ran a test over dinner. I started with Airscape's gapless process, and created two new processes. "Test 1A" had my parameters inserted from the top half of the table posted above, and "Test 1B" used my settings from the bottom half. The break...

I got all three processes into Excel, combined them all on one sheet, and then thinned it down to the essential stuff. I ditched things like support & raft settings, which aren't involved. I've attached a PDF that has the differences in settings hilited, using Airscapes's gap-free process as my ...

I'll find out. Extra restart distance is VERY sensitive, but a value of -0.05 shouldn't break anything. It does improve the quality of seams noticeably if you have something fussy, but if you use it, you should do a careful test to find the right value. I have a 9 process file that runs a 3 x 3 grid...

Your process is definitely simplified considerably from mine. I've spent a lot of time over the years making adjustments to deal with various print quality issues. The changes have accumulated over the years, and I could easily have slowly waltzed off into the weeds, or to the point where I stumbled...
