Machine will stop with error message, it just stops communicating with computor

I have created v bit text and outline, then jog the machine to zero point, and zero it out, hit run, it begins beautifully, then stops with error message,

If the suggestions here don’t help: contact


What is the error message?

Also some information about which machine and perhaps what version of your controller you are using would be helpful.


I have the Shapeoko 3, using carbide create and motion, I am new, testing things out, want to buy vcarve,but first need to make sure that this works, as far as the error I believe it says , error: cannot open port however I am unsure, I should take picture of it…
