I already built a repstrap that is able to mill polycarbonate and engrave circuit board but it is too slow and not as rigid as I want. So I decided to make a new printer with the same abilities but stronger, faster and self-replicable. It will looks like this :The design is inspired by the triangular frame of the reprap mendel.Differences compared to the standard mendel :- vertical X axis to quickly change the tool (extruder or spindle)- M10 and M12 threaded rods instead of M8 for better frame stiffness- 10mm smooth rods instead of 8mm for better axis stiffness- Precision doubling belt configuration inspired by Madkite's design : [ www.thingiverse.com - nema23 steppers for the X and Y axis instead of nema17- Each axis will be equipped with 4 printed linear bearings : [ www.thingiverse.com I will also try to use steel cables instead of timed belts for X and Y axis.[edit]picture update
