Chris, very cool. I don't have a drill press or a digital caliper or a ratchet set :P. I think I am going to scrap my current design and go with a bolt-together solution like a lot of the MDF machines; although I think I'll stick with making it out of pine. Any suggestion one way or the other?
I'm also going to take LeeWay's suggestion and reverse the rails and mount them on one large piece of MDF/Pine for the table portion, put 2x4s under it so it's off the table and the gantry will clear and mount the stepper motor on the side.
You think a router without guides is sufficient to make all the holes, slots and shapes that I need to get it together enough to make better parts for itself or should I get a jigsaw? I live in an apartment so I'm literally doing everything in my carpeted spare bedroom and can't spring for a decent workshop setup.
I'm considering getting rid of the all-thread and going with some cheap ACME rails from roton.com
As for the electronics, I went back and forth between a number of solutions and ended up buying a pre-made 4-axis board from Rockcliffmachine.com (
http://www.rockcliffmachine.com/electronics.htm ) and it was pretty inexpensive ($330) compared to some of the individual axis controller packages and it's a nice neat kit that contains everything you need (except wires from the power supply to the board). It even has an XML config for Mach3.
I'll post more pics as I start re-building it - but with my work schedule it'll probably be a few weeks. Thanks for all the comments - it's good to finally be part of the community.
