Tom makes a point. Did you get lazy and did not run the DC power supply to its fuse point? Did you not separate the VFD to its own pair of fuses? It almost looks as if you used the VFD terminals to break out AC power....I would have put overcurrent protection on the VFD by itself and then overcurre...

Is that a 120V or 220V supply? If it's 120V, the neutral should not be going through the main disconnect. Is the DC motor supply powered by the VFD??? This is a 220v power supply, the system is powered with 220v power. The white wires should be marked with tape to indicate that they are not neutral...

Another quick though. I noticed on one of the basic acorn videos that Marty put up he links the commons of his motor power supply and acorn power supply together. On my panel all of the commons appear to be “floating” that is none of them contact each other or are referenced to ground (unless a grou...

OK. I did some more testing and wanted to provide the observations I made. After a bunch of trial and error I have found that the machine has communication errors after the panel has been initially turned on. There is one thing I happened upon that allows for the machine to operate for extended peri...

Marty, It's almost as if you knew my problems wouldn't be fixed as I had hoped (I'm sure you did). I started it up today to start to finish the ATC setup and had significant communication issues. Please see the attached photo of the panel. You'll notice that the VFD cable isn't hooked in this photo,...

Marty,

I'll follow up with a fresh report and a picture of the box shortly. Thanks

You need to use the SHIELDED Ethernet cable. You should not have anything else running on the CNCPC other than CNC12. Sounds like you may have a ground loop. Please post pictures of your control cabinet and ALWAYS post a fresh report. Marty Marty, Thanks, I understand now that shielded ethernet cab...

Thanks for all of the replies. I think I addressed the communication issue. I believe the issue was the Driver on my Lenovo M700 PC. I'm going to write the details here for others who might have a similar issue. Issue - Long delays during homing, homing ends abnormally, axis travel limits are change...

Tom, Thank you for the reply. I am not using shielded Ethernet cable. It is routes away from other cables except at the near the point of entry into the panel where is is parallel for a few inches, but spaced away maybe 5 inches. I gave a shielded cable on the way and will have it tonight. (thanks A...

BTW, I am running mill pro, but actually have a router pro license.
