The 7I84 needs VFIELDA VFIELDB and VIN

Suggested wiring is to power VFIELDA and VFIELDB and leave W1 in the default
left hand position, so VIN get powered via VFIELDB.

He,

I have a 7i84 connected to a 7i77. Lcnc can see the device but the red is always on and I am not able to control the outputs. Could it because I only have 24v connected to vin. Does the field a and b niet power?


Thanks 
 

  So I decided to do a fresh install on the computers for my Mill and Lathe. The computers areDell Optiplex 9020 micros. I am installing Linuxcnc V2.9.4 ISO. After installing and then updatingI get an error message ofE: Subprocess /usr/bin/dpkg returned an error code (1)it also says there is an issue with initramfs-tools.all that said I am attaching a pic of the error message to help. I am sure I am missing something stupidI usually do. LOL
   
 

Did you try pinning the Ethernet IRQ to the last processor?

This usually make a large difference in Network latency

Yes, correct!
But I’m still having some issues with the config upload, which I’m currently investigating on the EC500 board.
If you're unable to change the config, you may need to erase the entire chip first:

Then flash the firmware again and upload the new config.

This worked for me, but it's definitely not an ideal solution...

not sure i follow about the speeds thing? maybe your configuration settings for default jog speed? not sure about the keys things, been completely covered up with work and haven't had any time to dig into probe basic recently. maybe ask the linuxcnc devs if they could add a keyboard assignment to the configuration? for lathe? if its such an issue im sure more folks would want a global resolution that translates into any gui running the lathe option in the ini.

Happy to help, just a small payback for all the help I have received in the past from this site and members.

did you get this resolved?
