I built my X-Carve Pro this weekend and ran into a strange problem. When I got to the step of powering up the controller I found that the moment I turned the unit on it tripped my circuit breaker. Here our local code calls for all new circuits to be GFIs and this was a brand new circuit.
I talked with support on Monday and they told me that they have been seeing this with people using GFI outlets but had not heard of it yet from a GFI circuit breaker. They asked me to use a different circuit that was non-GFI. Using an extension cord I was able to test it using a non-GFI circuit and it seemed to work fine.
This makes me very nervous as a GFI measures leakage between the hot leg of a circuit and neutral (corrected), indicating there is a problem with the circuit/device. Support says it is because of the current surge to the stepper motors. I am not really buying that the stepper motors when idle are drawing enough current to trip the breaker.
One of the first things I did in testing was to remove all cables from the controller and then try powering up the unit and it still tripped the breaker.
I suspect there is some kind of design issue with the controller that is causing leakage between the hot leg and neutral (corrected). Right now I am not comfortable with keeping my X-Carve Pro plugged in until I know more.
Anyone else has any experience with this?
