Im new to the forum, finnally got my machine up and running.

I had followed the directions for setting up the spindle and when it turns on the screen just blinks. Im not quite sure how to fix it.

Also how do you get the spindle to turn on automatically once you begin a cut? I had allowed the buildbotics controller but not sure if I need to do it on Vcarve.

Thanks for any help in advance.

In vcarve you can modify your post processor to start/stop your spindle
