So, I have spent the last week or so upgrading my spindle to a 2.2kw 220v spindle with VFD. I finally got it all up and running and it was actually working for a short time.
Today, I started a carve and it got partway through and it lost connection to the computer. I tried restarting the computer and going again… same result (different stopping place).
After trying a new USB cord, plugging the x-controller into a different power outlet and a few other things, it seems like the problem is with the spindle.
By the end of the day, whenever I started the spindle, it would immediately loose connection.
Here is the setup.
The VFD is hardwired to a 220v line directly to the panel.
The wire from the VFD to the spindle is a 16ga shielded wire that runs above the machine and nowhere near the x-controller.
There are no wires connecting the VFD to the X-Controller
When I unplug the spindle from the VFD, and hit the Run button, the connection stays on… it is only when the spindle actually powers up that it looses connection.
The X-Controller is on a separate circuit from the VFD.
What could it possibly be?
