Since I'm just getting my feet wet in the CNC pool, I want to see if anyone has any pointers etc. to make sure I'm on the right path.
Hi, forum! I just started building my CNC for cutting thin aluminum and plastic. It's based on a bunch of 8020 aluminum and the 305oz hobbycnc 4 axis driver kit. The x-axis is 5/8x22", y-axis is 1"x18" (y-axis it's thicker because they were spare bars I found). The x-axis bearings are based on a 3-point skateboard bearings. Y and z-axis a bushings.
So, on to the questions:
1) Can I use 2 motors in parallel for the x-axis based on the hobbycnc 4-axis board? (I figured that doing this will promote even movement).
2) Is it ok to use screw rod from home depot in order to get my project up and running considering that is will be used to cut aluminum? Should I worry about backlash on my axis'?
3) Any reason why my cnc will not be able to cut aluminum?
4) Any pointers on general setup? Things I should watch out for? Any things to keep in mind when setting up the z-axis?
5) Am I in over my head?
Thanks,
RynoSLC
