My first 3D printer was built in summer of 2014.? An extruder fastened in place of the router on a JGRO self built CNC router.? I used MACH3 to interpret the Repetier sliced G-Code.

The results were by no means attractive.? I learned a few things from that experiment.? My CNC router wasn't quite fast enough.? A heated bed was essential. And finally, the more mass has to start and stop the more shaking.? A CNC router, and this is a flimsy implementation, isn't designed for the rapid movement of a 3D printer.?

The printer would have to be a belt drive and some of the frame wobbliness would have to be changed.? But in either case, the more mass, the bigger the motors and then again more mass to keep the vibration down.? The current crop of 3D printers use size 15 motors and small hardware for a very good reason.

Of course for 3D printing movement is more important than torque.
