Hello again all!
I am making progress on my first build and have gotten to the point where I need a little help.
Im building a CNC for cutting small aluminum boxes (3"x4"), and PCB's.
I have the bottom of the frame designed using Autocad 2008 with the 8020 add-on (im making the whole frame from 8020).
Questions:
a) I need to design the bed which holds the lead screw on the bottom... but I dont know how they mount. I imagine when I purchase the lead screw it will just be a rod and I will need to get 2 bearings? Is there a standard size or attachment method? Can someone fill in the details please
b) I need to decide on a lead screw to purchase. I havent purchased an X or Y axis motor yet (I already own a 'Paul Jones instant Z-Axis Kit').
But I do not know how to properly decide what lead screws to get for my X and Y axis.
I see alot of talk about IPM and speed/torque conversions, but I am new to this. I'm worried I may need to do something like gear up/down.
Can someone please fill in the details on how I should proceed?
Thanks for help in advance!
I have attached a picture of the instant z-axis kit and also the Autocad design I have made thus far.
