Here's a video of tinyG controlling the machine to run a "hello world" job:
Here are the tgFX panels showing the correct settings for Shapeoko. Note that you may need to change the axis assignments and polarities for each motor depending on how you wired it up, which is one of the nice features about tgFX- just pay attention to your motor's coil pairs, and then do all the rest in the software.
And as a special treat, Alden's rundown of the setup, and explanation of the control principles. Thanks
Shapeoko and TinyG
CAVEAT: Be sure your machine is in mm distance mode before starting. The distance mode should be obvious from the command prompt: tinyg [mm] ok> not: tinyg [inch] ok> Enter G21 to change to mm mode (G20 to change to inches)
