6XD USB-C port gender

@Valveman said in 6XD USB-C port gender:

So can I assume the cord is male and the pcb port is female?

Yes, that's correct.

Update: I have my EERO working, as the left port works when connected to my PC. But there's no longer a connection being established when patched to the 6XD Ethernet port. Reiterating, the system was powered on and just idling, when the connection suddenly failed. I do not know how to troubleshoot the Duet, regarding IP addressing, or prove the Duet needing to be totally replaced. additionally, I was able to ping the EERO and get a good response. But pinging my Duet IP 192.168.5.227 returns nothing.

@Valveman send M552 to the Duet over USB and check the response, to see if an Ethernet link has been established and what its IP address is.

@dc42
I'm not sure how to do that. Type M552 at the Command Prompt? That attempt results in just a non-recognized command. I have the cable plugged into the USBC port with no external power applied. The board has three led's lit; 5v, 3.3v, USB. And the normal blinking red status led. Please advise.

@Valveman you will need to use a serial terminal program like PuTTY or similar, see https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-2-connect-your-duet-via-usb

Members,
Slowly catching up. Lol. With YAT installed, and simply sending M552, I receive the following:
Ethernet is disabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0<LF>ok<LF>
Again, a week ago the IP 192.168.5.227 eero was using, suddenly lost connection. CNC was powered on, but not moving.

@Valveman from YAT, send M552 S1 to enable Ethernet. Also send M122, and post the response. You can copy and paste the text.

I think most likely is the SD card is not being read, so config.g is not run at startup, and networking is not enabled. Check the SD card is properly inserted in the socket. You can run most of the SD diagnostic commands from YAT that are described here: https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#troubleshooting-sd-card-issues

Wow, what a quick and concise response to my situation. Many thanks for the guidance. But before I go any further, I want to do a re-work to the spindle motor power supply.
Simply put, it's nothing more than a 120vac rectified DC voltage regulator, using a single FET transistor that regulates the voltage from 0-100v. And while it works perfect for this light-duty cnc-router, it does not offer any electrical isolation from its input to output. The PWM to DC converter board that was chosen to couple the 6XD to that supply, offers no galvanic isolation either. In as much as things have been working fine for a very long time, I can't help but be concerned about the possibility of ground current being looped through the 6XD, via its 15vdc [isolated] supply, and that hot-line-side spindle supply. With the common wires disconnected, I measure some 27v between them. While all it takes is two fingers touching them to cancel out the meter reading, it's about the only issue I find, that might have caused the problem in the first place.
Replacing the PWM-DC unit with an opto-isolated version, the ground loop circuit will be broken. Then I will proceed with the business of trying to salvage my precious 6XD. Thanks for listening.

@Valveman I don’t have much experience of spindles, but our recommendation for opto isolated PWM to 10V converters are here: https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_CNC#connecting-a-spindle

I'm using one of those pictured.

@Valveman then you should be okay. Alternatively, RS485/Modbus support has been added to RepRapFirmware recently, so you may be able to control your spindle VFD that way.

All fixed!
I cannot explain when or how, but config.g was gone. It took my [digital] son all of five minutes to find [that] to be the whole problem. Backups took care of it.
I just wish I had video of exactly how I caused it.
I must slow down and be much more careful. Now I can continue with my spindle.
