So I have been interested in machining and CNC for a few years now. And almost started building one of these CNC routers a few years ago but the price was just a little out of reach then. Well steppers and controlers have come done in price quite a bit in the last few years and it is time to build one.
Work area will be 26x52x7, with an A-axis coming later after the machine is working properly.
Going to keep a parts list with prices right here at the top of the thread for anyone that wants it.
$489.87 Keling 4-axis kit with 495oz/in motors (Includes $30.87 S&H)
$9.57 GT (3mm) Pitch, 150 Teeth, 9 mm (.354) Wide Neoprene Belt
$10.75 GT (3mm) Pitch, 200 Teeth, 9 mm (.354) Wide Neoprene Belt
$20.62 2 x GT (3mm) Pitch, 60 Teeth, Polycarbonate Timing Pulley With Aluminum Insert ($10.32 ea)
$60 24 x AXS 1614-2RS Bearings .375x1.125x.375 ($2.50 ea)
$25.08 6 x AXS R8-2RS bearings .5x1.125x.3125 ($4.18 ea)
$55.98 2 x 4'x8'x3/4in MDF Home Depot ($27.99 ea)
$23.99 1 x 4'x8'x1/2in MDF Home Depot
$695.95 Total - updated 10/12/07
And here are some renders of the nearly completed design.
As you can see I am going with belt drive on all axis because I like having the steppers hidden away on the inside of the machine. Not hanging out ready to be hit buy someone moving things in the shop and not paying attention.
I know this is a more complicated way to do things. And will be proto typing one drive axis before actually building the rest of the machine to make sure my design works.
Please give me feedback you have.
