#Hemera retraction settings upgrade

The extruder is a NEMA17 stepper in a U-shaped metal frame with a conventional extruder bolted to it. I had made some very simple changes to the extruder, but it was mostly stock and that was a pain. The extruder on the A8 - actually, the entire X assembly - doesn’t really change on the AM8 build. Having a solid metal frame on the printer really turned it into a world-class printer. Looking for a pandemic project, I decided it was time to take the plunge and the results were great. I merrily improved the printer quite a bit over a relatively short period of time and I also bought a bunch of aluminum extrusion to rebuild the frame to the AM8 plans you can find on Thingiverse.Īn AM8 is Born The All Metal Hotend in Action Finally!īut life happens, and that box of extrusions sat on the shelf for a few years. But it is a fun printer because you really need to do some work on it to brace the acrylic frame and fix other shortcomings. If you’ve ever thought about moving from a traditional hot end to an all-metal hot end, you might want to hear me out and maybe I can save you some trouble.Ī few years ago, I picked up an Anet A8 for a really low price.

This is the story of an upgrade gone bad, although the ending is happy enough. If you are reading Hackaday, you probably know how that is.

What I do enjoy is building, fixing and even more importantly improving the printers themselves. But Patrick correctly realized that I don’t actually enjoy printing things that I need. That may sound odd, because I built a printer back in 2012 and since then I’ve built a lot of printers and I currently have at least three in my lab. My son, Patrick, has observed on more than one occasion that I do not like 3D printing.
