So, the build starts with a 20mm X 80mm X 500mm v-slot extrusion.
Add a second one...
Then a third.
These will become the bed.
Bolt them together with some plates.
I used a couple of C profiles for the ends. One of them has been drilled to allow the drive shaft to pass through.
I used a Nema 17 sized stepper motor with integrated tr8 8 shaft from Pololu.
And at the other end is an 8mm bearing in an OpenBuilds housing.
The C profiles are bolted to the bed with angle brackets making sure everything is square. On the sides are 20mm X 40mm X 500mm extrusions attached with angle brackets. Make sure to fit the drive nut before putting together the ends.
So the next step is to fit the X-large build plates to run on the side rails and fit a cross beam to connect both sides
The Y gantry will be 20mm X 80mm extrusions bolted to each side. This is just a proof of concept and may eventually change.
This is the state of my build as of 5/12/2016.
This is a design for a desktop CNC machine. It may be a router or laser. I am undecided as to the final design.
