Hello , I am new to the forum, but I've been reading it for a while. I have a friend that has access to a big CNC and he will make me some parts free.
I am about to order a 4-axis controller and four 305oz-in steppers (hobbycnc.com) with a 32Volt unregulated power supply.
Then from "harbor freight" Sieg X2 mini-mill and a 4inch rotary table.
My plan is/was/maybe ; just mount the steppers to the handles and go.
When I strip a gear then I will do the Belt Drive upgrade.
It is going to be used for PCBs with fine traces, Art, engraving, small parts, and very small parts.
What is the backlash like out-of-box? Am I going to have to add Ball-screws?
I have seen here where they have added Ball-screws to the Z-axis, but did they do the same with X and Y axis?
Is the Backlash visible?
Do I need to do a Water-Cooling system for the X2 motor?
Do I need Heat-Sinks for the Stepper motors?
I only have about $500 for a Mill; Do you have any recommendations?
