Go ahead and download the Mach3 demo. But first watch the Mach3 tutorial videos. There are a dozen videos, but the first 2 or 3 is all you need to understand the basics. Much of what is taught in those videos will translate to your machine and other software too. Then load the software, and load your favorite DXF. That about discribes where I am in this sport too. So get that demo download and watch those videos.
Regarding the laptop, yes I've heard that many laptops produce only 3 volts and may not work with drivers that require 5 volts. You might ask that question to Dave R or Mike B as I'm sure they know the input limits of their driver board. That's a good reason to get a BOB (breakout board). BOBs serve several purposes, and boosting the voltage from 3 to 5 volts is just one of them. Check with HobbyCNC if one is required, and how to hook it up if it is required.
I concur that the JGRO design is great, and perfect for my building skills. Glad to see another builder posting their accomplishments.  |
