Here is my idea for a 3d printer fram that will also work as a frame for a mini mill.
I was trying to come up with a way to build a machine that would not get jammed up or damage stepper motors if I used cutting oil.
I have a CNC plasma table, and researching how to DIY a router I came up with a idea to basically build a router table on top of a box.
My inspiration is the HAAS machines along with the makerbot and other designs.
this rendering does nto show a complete machine as I still have to draw a gantry and other major parts.
The build area if it is a 3d printer is 5 cubic feet. 450mmx450mmx900mm roughly.
It is made from 1 and a half sheets of 5mm steel plate. I am designing suitable fastenersto bolt it together as I am concerned that the heat of welding will cause it to warp.
the hardware for milling and printing will have to be drastically different. I need a light weight gantry for printing due to inertia forces and the use of a belt drive.
for milling a acme screw drive is my choice along with a very strong linear bearing arrangment, or rack and pinion gearing.
Some people might call this overboard for a printer, but for a milling machine it should be quite strong and stiff compared to the plumbing pipe and angle bar models I have seen.
