Ok, so I am starting to aquire peices and doing planning on my first CNC 3-Axis machine!
Here's to being broke for the next few months.
The design will be similar to the Data-Cut. I am planning on a working area of 24in (Y-Axis) x 30in or 32in (X-Axis). The Z-Axis will be using a 7.5in THK Rail.
1) THK Rails for the X, Y, Z Axis.
2) Ball-Screws for the Y, Z Axis.
3) Belt-Drive for the X Axis.
All of the above will be from Ebay. By my estimate, will run about $250-$350.
The parts I am not sure on:
1) Router. I was thinking of a 1/2hp Porter-Cable?
2) Servos. Not sure here.
3) Controller and PSU. I would like to go Gecko, but they are $$$.
4) Table/Frame. Thinking of Alum. Extrusion like 80/20.
I am mainly going to be machining Acrylic, Plexi, Poly-Carb, Delrin/UHMW. I would also like to be able to machine Aluminum stock up to 1in thick (obviously would be multiple passes).
I am trying to stay under $1000 (hopefully $500) total cost.
So, thoughts? Ideas? Things I should change?
Thanks in advance for the help. This is a great community!
Cost so far:
1) Two 26in Slide Assemblies: $130 (Ebay)
2) Porter Cable Router: $136 (Amazon.Com)
3) One IKO Linear-Rail (Z-Axis): $15 (Ebay)
4)
Framing:
- - A) 80/20 Aluminum Structure - 47" x 2: $33 (Ebay)
- - B) 80/20 Aluminum Structure - 36" x 3: $36 (Ebay)
Total: $350
Budget Max: $1000 Left to Spend: $650
