Question new stepcrafter's man soon ...

Hello,

Since long time, I did my own "CNC" to cut foam with hot wire. I modify this frame to use it as CNC and cut some pieces for RC controls models, but not only.
I noticed that my machine has too low power to work on some materials and not enought precision for some projets, than I decided to have a new solution. By the way, family, daily work doesn"t let me enought time to do it myself. Moreover 3D printing has also big interest at the end.
As I remarked stepcraft machines last year at the Dortmunt fair, I have today a big interest for the 420 model ...

I have some questions before the final validation of my shopping card ... I'll summary my questions, but please just let me few ours to be as clear as I can to be understood.

I'll be back very soon ...

Best regards to all of you.

oooo I wonder what the Questions are

@stu: You can read about the questions in the other thread

@demi: But with the other thread in mind, what software do you use for your selfmade machine? What interface does this machine have?
