Alan,
My first post on this great forum.
I spent ages browsing your site. The picstep controller is now on my to do list. I'm just in the process of evaluating all of the designs out there. I basically would like to make some form of pc controlled router / engraver.
I hope to start building the picstep next week. Then hook this upto TurboCNC.
I'll let you know how I get on !
I'm hooked already
