Hello all, I've been on the DIY CNC Plasma table for a long while now. The mechanics of the project don't scare me much, I just have a lack of understanding of the electronics and computer interface. I have a fairly in depth controls background, however I have never worked with a setup along these lines. Where is the best place to read up on the control system aspect? I am looking to build a bare bones 2 axis table (4'x4') to start. Head height will be controlled manually for now. What is the most cost effective way to accomplish this? I understand I will likely need to purchase software, but is there a brain or main controller outside of the servo/stepper motor drives. I'm sure there is a DYI CNC for dummies post on here somewhere, I just am having trouble finding it right now. Any help is greatly appreciated.
Thanks,
Mike
