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?

I did set the acceleration in the TRAJ section, it does affect the acceleration
but the scaling seems not to be correct. The Acceleration/Velocity bounds are important
since they are per joint physical limitations.

(sorry if I am getting out the sandpaper when construction is at the chainsaw stage)

It is great so see  a jerk limited profile working with LinuxCNC as it fixes the inevitable
following error at the start/end of motion due to the impossibility of having instant force
application in any real drive system.

yeah that delay is a bugger.. the drive should be enable constantly and just be looking for a direction voltage and step pulse stream. i would have the drive enabled anytime the the machine is on and not estopped. and have it sitting idle waiting for pulse command.

Are all the drivers the same, or did you do your check all axis with the same drive

hi
the same driver for all axes.
I tried to unsolder the chip, without success
the board does not respond, for now I do not think I will buy another
thanks for the support
 

Hi guys

I couldn't resist and bought a new board, this time I opted for a 3-axis EC500,
it has LEDs that indicate the I/O status, I think it's more complete.

I tested it with Mach3 to make sure it was working well, given the previous ones,
and it worked on all three axes.

When loading the firmware, it got to 29% and timed out and everything froze,
the DAP wasn't receiving signals.
I reread page 115 of the thread that talks about how to unlock and after having
bridged BOOT_MO and 3V3 I managed to delete and write the new firmware!!

Now all 6 axes work.

Thanks again to Scott and to whoever made all this possible.

great!

Do not ever run an OS from a USB key long-term.

The flash memory will wear out and the bandwidth will be limited b/c USB only has 1 unidirectional dataline.

It cannot read and write simultaneously.

USB 3.0 and greater fixes the bandwidth issue, but the weardown of the flash memory is still very problematic.

I recommend you install Ventoy to a USB, download an ISO of LinuxCNC from the downloads page, and install to an HDD from that.

Chrome downloads files slowly for some reason, use Firefox, curl, wget, or JDownloader to avoid waiting all day.

You can reduce latency by setting the CPU governor to performance.
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor > /dev/null

I prefer Ubuntu's GRUB to Debian's.

(the Debian version is ugly)

Very nice next blacklisted intel backdoor! six windows of youtube no junction error!! But nest use rustdesk error coming 
 

.exe = Windows.

On a Unix-like filesystem, files must be marked exucutable to be executed.

It's a security thing.

Chmod +x will mark a file as executable.
