Note - there will be no further updates to this page. Any further updates will be on the FB2020 Github page - https://github.com/AxMod3DPrint/FB2020 Originally based on the Fusebox, this printer now has become a design in it's own right. Most major parts have been redesigned from the ground up or have been overhauled in some way. Should you want to buy a full kit or buy the printed parts you can use the contact form on https://3dprint.axmod.co.uk to order. The Ethos of the Fusebox was to keep parts pricing low, which at the beginning of this project, was the same aim, however, it is now to improve the FB2020 to a point where it's pretty much it's fool proof and highly reliable. I want it to the point where anyone with a set of Allen keys can put it together. I'm happy with the frame rigidity, yes, it's not as rigid as it could be, but I still want to try to keep costs down where possible, by using printed plastic parts this helps a little. I've added a list of upcoming changes below. All files should be orientated correctly for printing. Any file marked Culain is an original file from Culain's design and no physical changes apart from mirroring and orientating correctly have been made. NOTE: All bolt, rod and hot end holes on the STLS for the Carriage and Carriers have a 0.4mm tolerance. If you need less or more, grab the SCAD files. There is a setting in there to change it. Belt Tensioning The best way I have found is to loosen off the motors so they are on the end of the bolts in the Y direction. Pull the belts as taught as you can manually then tighten the motors back up to bring the belts to full tension. I'm working on a better tensioning system currently. https://youtu.be/WNDfNemOfFM - Gayer-Anderson Cat in Whiter Generic PLA at 80mm/s at 0.1mm layer height. https://youtu.be/yOhGpVYnDCI - Aztec Chief in ColorFabb NGEN at 80mm/s at 0.28 Layer Height https://youtu.be/bmPf83OeyGA - Printing the Rigid coupler in ColorFabb NGEN at 80mm/s & 150mm/s Travel - retraction settings were being worked on, so the print is a little stringy.. https://youtu.be/XaOWR-UzrOI- 2nd Print - #3DBenchy Timelapse.
