I wonder if anyone else had seen this. After my upgrade, everything was running fine with simple projects. I decided to do a big project that I needed to use one of my Pro Days on. I started the job and halfway through, the X-Carve locked up. I tried a couple of more times and it continued to lock up but with no consistency. The next day I tie a couple of other simple jobs and the same thing was happening. After reading the forms, I bought a new USB cable and I even switched computers. I am running from a Macintosh that has nowhere near the issues PCs have with USB.
After many trials, I notices that the machine stopped just as the heater blower kicked on. The heater is a BigMaxx by Mr. Heater and is mounted directly over the X-carve. It is also plugged into the same circuit as the X-Carve. So I moved it to another circuit on a different phase. It continued to happen. Next, I ran an extension cord to the house which is a whole different service. Still happened.
So I have ruled out the computer, the USB cable, and power. Finally, I moved the X-carve to another location in my shop and it works great. The best I can tell is some sort of radiated emissions coming from the relay on the heater blower. It also happens when the heater blower relay kicks off. Moving it to a new location works, but is really not great for the workflow in my shop. Has anyone else seen this type of issue? Is there a way to shield the X-carve or the heater to keep it from happening?
