Hello Everyone,

I am looking at building one of these machines for home use, I have a Shopbot at work that I use pretty much everyday.

Are the drawings for this machine complete?

Do they explain all the stepper/servo/controller/driver
Software/acme or ball screw requirements?

Manufactures and Part numbers included?

Wiring Schematics?

From the drawings/plans can you build a complete ready to run machine?

How much "engineering" do you have to do on your own?

I just want to make sure that its really complete as I don’t want to have to scramble in the end trying to figure it all out..

Please let me know what you all think

Yes the plans are complete. All part numbers as well as where to buy is included. The machine uses acme screws on the Y and Z axis and 2 rack & pinion gears on the X axis

You have to do no engineering - just follow the plans.....

Hi GunnyShow

I just bought the plans and am very happy with what i got. If you change components you will have to do some of your own "engineering" but i dont see any need to change the design.

I hope to start builing my CNC router in July and hopefully will make it a little larger.

One Question to Ninewgt, I am having trouble finding the X axis upright Aluminuim of 4,1/2" x 3/8 , would it be ok to use 1/2" Aluminuim on the upright ?

What piece are you talking about ??? You have me confused - You mean the 3/4" piece ??

The X axis has the rack support piece and the horizontal piece that the linear rail mounts to - thats it. The rack support piece is 3/4 and needs to be 3/4. The other is 1/2 and needs to be 1/2 also. Reasoning : These pieces together form a long angle beam basically - bolted together with socket screws as specified they for a very straight and rigid piece to work with which makes leveling the machine and lining it up easy. If you use material here that can flex..... it can lead to problems. I am not saying you cannot but extra caution will be needed when you go to level the X-axis as indicated in the instructions.......

Hi ninewgt


Yes sorry I meant 3/4" , hazard of living in a Metric country

No problem......

You really do need to try to use the thicker stuff - You CAN do it with 1/2", just make sure you keep it all level and straight as I explain in the plans.
