halui.mdi-command-NN pins not showing up

Category: HAL

Looking through halui.cc I don't see anything that would obviously fail if joint 0 is angular.
But as an experiment I would be tempted to switch COORDINATES to ZA to see if anything changes.

It might be instructive to see which halui pins exist, to give some indication on where the component load fails:

github.com/LinuxCNC/linuxcnc/blob/master...mc/usr_intf/halui.cc

Assuming that linuxcnc is "alive" "halcmd show pin halui" should give us a pin list to look at.

I think that, if you connected to the internet, the date and time would correct themselves. So I would start with debugging the internet connection.

I have EC3A-IO1632 module and trying connect it with linuxcnc.
I am following instruction from here forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step and stop at ethercat slaves step.
When trying list slaves with ethercat slaves command I get empty output.Output for ethercat master

I'm not sure, to be honest. I wasn't specifically looking for the ethernet version of the boards, as they don't seem to be the most popular option here (or at least that's my impression).

From what I've read, the ethernet version usually has a 1 kHz refresh rate. My goal was to find the most reliable configuration possible, so if I messed something up, I'd have a solid backup.

No idea how you got to that conclusion as probably 90% of new posts are for Ethernet cards, and i have at least 30 in daily use with no issues ever.
And most ethernet Mesa cards can easily do 4Khz, so there is no difference between the interface types, at least not major differences in use. Also have over 30 of PCI and PCI-E cards in daily use, with no issues ever.

My machine has mpg wheels to control feed and spindle, halui.feed-override.counts and halui.spindle.0.override.counts
Is there a way, to make the sliders follow the adjustement with mpg wheel?

Yes, a 7I73 (or other sserial device) can connect directly to the 7I97T

1 KHz is the default LinuxCNC servo thread rate and is typically fine for
normal CNC machines with velocity mode servos.

You can add multiple Ethernet cards with a switch or multiple Ethernet ports

One more problem, LinuxCNC is using 3-axis (xyz) readahead, so if you are using xyz+(abcuvw) axis blending in G-code command, the speed will be very slow
