I am new to the whole CNC thing but not to the fabrication aspect.
I was in a friends shop watched his CNC machine and had to have one. Being a Carpenter by trade, I conjured up many uses for one in my shop Ah the justification of a new item. I went online and found that The shop bot was a little cost prohibitive. Further research I stumbled upon a jgro Free Plans, I downloaded and looked over the plans and the decision was made I could build this and I will with some mods here and there.
I built my base from aluminumn extrusions in order to eliminate the torsion box the gantry was per jgro the dimensions of the whole unit are a little larger than the plans.
(2) days I built the base, and gantry it performs flawlessly on all axis. Now I am entering the difficult part.
where do I get the acme rods what size and pitch? good price?
The electronics, I found a package which included nema 23 stepper motors on buildyourcnc.com are these good motors/ strong enough? is anyone familiar with the package that i speak of?
Is Mach3 the program to use? I wanted to run this machine off of a lap top that I have but I just saw that laptops are not supported by mach 3 is there another option? I have only this laptop that is a pc everything else is mac.
Last question for this post:
I built the Machine, order the electronics, install and wire electronics, load software, connect electronics to computer, run program, CNC will function?
Is it that easy? I suspect not.
Any help will be greatly appreciated as I am pretty sure that I will need quite a bit of it.
