Mendelmin 1.0

Açıklama

]] Feel free to use parts from this as you please, but if you want a lightweight extrusion printer you should build the flexMendel by dkennel instead. [[ After a long hiatus, this is the fully functional and tested Mendelmin 1.0. This is a solid upgrade for someone still using a Prusa i2 with a MakerGear Plastruder, who has access to a laser cutter. This printer has 230mm of vertical Z height, and thanks to an aluminum extrusion frame with steel bracing brackets, it is very rigid and strong. It currently uses a combination of lasercut and 3d printed parts. The original design used only 3d printed parts, but I was unable to get the precision and strength I wanted from the 3D printed Z and X carriages, which ended up being over-constrained. This problem has been solved with laser cutting. Pieces are cut from 1/4" acrylic plastic, which can be done on a fairly low-power laser engraver (I used a Trotec 100). Lasercut pieces slot together and are bonded with acrylic solvent. Changelog: 2/17/2015 Replaced all parts on the X and Z carriages with components designed to be laser-cut. . Added extruder fan duct . Rotated Plastruder assembly 90 degrees for more X distance. . Initial testing: works 100%! New RAMPS + Taurino Power (Arduino Mega 2560) case added to 0.1.5. Designed to be printed in flat pieces, to minimize print time (z is by far the slowest axis). . RRD Smart LCD controller case added to 0.1.4, mountable on any horizontal rail. . Z endstop mount retooled! Included in 0.1.3…
