Having read through all of this and the associated links, none of them solved my issue. The issue was in the post-processor and can be found in...
THANK YOU!
It’s a Dell workstation laptop. It would have to be in its power supply, no? The USB is DC grounded and it loops back to the controller. Wild....
Yes sir. Alex won the prize. Was the laptop… On the other hand, I’ve learned a lot from you. I’m in your debt. LEDs light up green and the probe...
So this man walked into an openbuilds thread and suggested that it might be the laptop feeding the controller… and it totally turned out to be the...
Took one last stab at the VFD, thinking there may be some short between DC GND branching off to EARTH. Probed the EARTH terminal against...
Sorry. Don’t know if you saw my update. I tested for continuity between DC GND on the controller’s power supply output and its IEC cable EARTH and...
Right. Well, again, I’ve eliminated ALL of that and have gone directly from house EARTH to +5v SIG and it’s quite reproducible. Happy to send a...
Then I don’t know what to say b/c if I run a lead directly from IEC cable EARTH (essentially house EARTH) to the +5v SIG, it immediately finishes...
Sorry that was a typo: “If I remove the tape and allow the machine to EARTH, the +5v from the magnet instantly drops to 0.5v and the probing...
Right. So I misspoke. I assumed that the machine was DC grounded. It is not. Please see my post from last night, prior to this one. There is no...
I think I’m understanding. Then yes, DC GND is not connected to the machine. There is NO continuity between the machine and GND on the controller...
Peter, I have taken apart my VFD enclosure to inspect the wiring. Everything is apparently where it should be. I have traced with, per your...
The answer is to use ultra thin shipping tape and give one wrap around the spindle. Then insert back into the spindle holder. That will isolate...
I guess the problem is that the magnet energizes the entire machine and b/c the workpiece is aluminum, the plate closes the circuit as soon as I...
Yes, I hear you. I suppose let’s start with the basics. If I attach the 5v lead to the end mill, is it expected that the entire machine becomes...
Purchased the Probe from Openbuilds and am using on an Anolex 3020 with their 1.5kw VFD. I’ve read the threads on bad wiring and $6 options…...
