First trial run today, actually 2nd. I entered the wrong belt pitch into the reprap calculator for the first run so the image was stretched out. Now that the settings are right, everything seems to be working. Image from vicious web site converted to dxf, then converted to gcode using dxf2gcode, and finally the Y axis toolpath wrapped around the E (Extruder) axis and fed to MPCNC running Marlin. I like the 3 jaw chuck but I’m thinking of whipping up a scaled up ER-collet type system since I’ll mostly be working with round stock from hope depot. Getting there though…
