This morning, I came in as usual and powered up the 4 xxl. Usually the big round button on the spindle controller will light up. This morning, it does not. The speed indicater is flashing 0.0 as usual but but the button won’t come on. I’ve checked all the cable connections. Not sure where to go from here.
Sounds like the PCB inside of your VFD box gave up. Carbide3D support will need to send you a replacement.
You can check for 24V coming from your 4xxl by probing between the red and black wires going to the VFD box. If you are getting the 24V then the above statement holds true.
The VFD was sent via USPS on 10/27. I have not heard anything more from you. Did you get the package? Do we have any idea of the turn around time? Works piling up.
