Cartesian Completed

Completed the Cartesian assembly and did some basic testing. Still a few bugs to work out in connecting the RepRap up to the computer, and the power supply can't run more than 2 motors at a time.


The frame is pretty much completed here, all the major components are installed and the chain is attached.











This is the solder joint I made to make a continuous chain that keeps the 4 vertical screw drives turning in unison.











The stepper motor driver boards are attached and hooked to their motors.

Cartesian Frame mostly complete

Here are some pictures from the final steps in the Cartesian frame. Once completed it should be able to move the tool head in 3 axis.


Here are the 4 drive shafts for the Z axis that make the platform move up and down. The shorter rod is the one that attaches to the motor and a chain will ultimately make them all turn in unison.










The frame with the Z drive rods installed.












Frame with the top assembly installed












The platform installed along with the extra cross braces on the sides.












X-axis installed on the top of the frame.

Beginning the Frame

The next step is to begin assembling the frame which will hold everything together.


This is the base of the frame. The final RepRap will look like a big cube.












This is the assembled x-axis which will ultimately sit on the stop of the RepRap.












Here are the upper corner assemblies for the frame.

The parts so far

All of the assembled parts so far. The x-axis components are on the left, and the base frame components are on the right.












A close up of the optical endstops, these will turn off the motors once an axis has reached it's end point to prevent damage to the frame.

Power Supply

Converted an old PC power supply for the RepRap.

Steel Rods

Cutting the smooth and threaded rods to various lengths.











Here are all the final cut rods.

First Assembled Components

These are the first two assembled parts. The one of the left will hold the motor the X-axis and the one on the right will slide along the X-axis.

Parts

All the parts for the assembly of the positioning robot.


The nuts and bolts, all metric since contributions to the project come from all over the world and it was originally developed in the UK.















Here are the lasercut parts made out of Acrylic.


























On the left are the steel rods used for the frame, silver are the threaded rods and the yellow ones are the smooth rods.

Stepper and Sanguino

Below are a series of pictures from the initial round of electronics. For this first version I am building on the needed electronics to get the Cartesian bot up and running.

My workspace for the RepRap project along with the bits for the Sanguino board.












Here is the completed Sanguino, which is used as the main control board and computer interface.












This is the stepper motor controller board.













Another stepper motor controller with the attached stepper motor.

Rep Rap!

This is just going to be a log of the progress of my RepRap project and then going forward other Sheltronics enterprises.
