@MrBuildernate Yes, I am familiar with the 80/20 extruded aluminum. I don't know how well the nylon bearing and the amount of play that will have on the whole system, but it sounds pretty good. Alternatively, you could also use v-groove type bearings with hardened and ground steel rails connected to the extruded aluminum. This aluminum has great properties for structure.

@MrBuildernate sorry...wrong number....that torque number is wrong

@anajonesr right now i calculate that i will have about 100 lb gantry. with the coefficient of friction at 0.17 for my slides i should only need a torque of 2.8 lb-ft. (considering the size of the machine!) btw the slides that i found make the bearing system way easy but unsure if it will work in pruduction. i found them on a website called 80/20.com its a nylon linear bearing with a extruded aluminum rod. amazing stuff.

@MrBuildernate the sprocket is directly connected to the motor shaft. Idler sprockets help the chain use most of the drive sprocket pitch diameter. There are 9 teeth on the sprockets and the pitch is .25", so the machine travels 2.25" in one turn. With 16 microsteps, I am able to achieve 1422.222 steps per inch. The motor size will depend more on the weight you are moving with the motor.

Can this machine cut in all 3 axes simultaneously?

@EveryonefromBnet Sure. This is a natural feature of all CNC Machines.

My dad and I are wanting to build one of these to carve out solid body guitars and necks. Was it hard to build this? Where could I get plans at and do they cost any money?

@tharrington11 This particular machine is sold as a kit. You will have to go to builyourcnc to get full details.
