One of the corner angle mounts for my Reprep printer being made on my CNC machine. As a kid, I was a huge fan of Science Fiction Novels, but never did I really believe I’d see the day where I’d have a robot, that would make me another robot that could then replicate itself. I think one of the greatest things of our era is the ready access to programmable chips like the ATMEL ATmega series. These are the processors used on the very popular Arduino and Sanguino boards. My Reprap will be powered by Sanguino running on an ATMEL atmega eventually. More on this topic in a later post. Today is all about showing bits and pieces of my reprap 3d printer.
The Left picture shows the Y Axis set up. The build platform will be mounted to a carriage that runs on those four 12mm linear bearings that are seen in the picture running through the center of the chassis. I need to get a belt with 19 less teeth then my current or cut the belt and clamp both ends to the carriage (the 1/4″ aluminum square in the pic). The pic on the right shows the Z Axis as well as the drive motor on the X Axis. The X axis will have the stepstruder printing heads on a carriage moving on 4 8mm linear bearings.
The left pic shows the idle side of the X axis as well as the other side Z axis. I chose to go with the dual stepper motor Z axis over the belt driven dual leadscrew set up. I have tested it with my zac built stepper driver set up run by a 555 timer pulse generator circuit to drive a pololu A4988 and it works well. I imagine I’ll have to check for lost steps and align the printer periodically with this set up. The right hand picture shows my milled stepstruder. It’s roughly based on the MK6 Stepstruder sold by Makerbot with some Zac-provements. I still need to order a heater cartridge from them and machine the shaft, heat break standoff and some other pieces to finish the plastistruder unit. Eventually I hope to have a double extruder head set up so I can run a water soluble support material on one head and the build material on the other, or to do multicolor builds.
