When axis opens the gui, the axis dimensions are already present. From tests done, when I had the same problem with debian 12, as soon as it reads the loadrt lcec command, the dimensions appear on the pins in hal, relating to the individual axes.

 
linuxcnc-ethercat version?  

i hope to help with this analysis , it is made by AI, and this try to understand ,    

If they're upstream of the VFD they're called 'line reactors' and smooth out incoming power ripples.

If they're downstream they're called 'load reactors' and smooth out the power to the motor.  Reduces heating in the motor, especially useful for older motors which aren't rated for VFD use and which are going to be run at speeds lower than nameplate rating.

Grease - you can flush out all the greased components with kerosene, then blow out excess with air, then regrease with whatever flavor you want.  Disconnect each grease circuit and flush each component separately - this will help identify any clogged or broken lines.  When you've cleared all the individual circuits out, flush any manifolds and header lines.

Could be from a number of sources.  Suggest disconnecting the ballscrew nut (or nut mount) from the X-carriage.  This will allow you to move the carriage by hand, as well as rotate the ballscrew in it's bearings, and also the nut on the ballscrew.  Should help you identify the source of crunchiness.

Which bearings?  Your machine has quite a few.  Some are cheap, some are not.  Your wallet will determine what you can replace... but if the bearing is easily replaceable and remotely suspect, I'd replace it.  You can usually find NOS name-brand bearings on ebay for decent prices.

Spindles are typically controlled through the NML interface by the GUIs, so if the GUI doesn't support multiple spindles you might have to use MDI to turn on and off the auxilliary spindles.

THat said, flexgui is mane to be flexible, so maybe there is suopport?
I haven't used it yet.
 

Thanks Andy.  I'm trying it out for the first time now.

All machine functions are already handled with hardware controls; I just want displays for all three spindles.  The only on-screen control which could cause machine movement of any type will be an MDI 'run' button.

I'm guessing FlexGUI is new enough that @JT hasn't had anyone bugging him about outlier configurations much.

See if you can add isolcpus=3 to your kernel boot file. I have done it on a pi but can't remember how
It should improve latency.

I hit buy on the servos this morning! My order was at the weight limit so i couldn't even add couplings to it and i'll have to place another for the extras, but i can use the us store for that and reship as well. Regarding the cables, of which i need at least 2 longer ones than they come with the motors, i'm guessing i can't chain them and i just have to replace with the longer version, right? Also, is the one for the servo with the break completely different?

Der VFD scheint in P02.10 nur eine feste Frequenz zu unterstuertzen. Damit koenne man wohl pruefen ob er z.B. eine Mindestdrehzahl hat. Z.B. 100Hz oder 6000UpM. Aber er kann wohl nicht vergleichen, ob die Vorgabe durch Spannung erreicht ist und dann erst schalten.

Wenn du ganz viel Langeweile hast, kannst du dir auch die ModBus Implementierung anschauen:

github.com/xsnoopy/LinuxCNC-Yalang-yl620...d?tab=readme-ov-file

Der RS485 Anschluss scheint stoeranfaellig zu sein. Ich wuerde das maximal zur Rueckmeldung der Drehzahl nutzen, nicht aber um die Spindel an und auszuschalten.

Falls du ModBus mal testen willst, nimm bitte einen USB / Serial zu RS485 Adapter mit A/B und GND (Masse). 120Ohm Widerstand am Ende der Verbindung nicht vergessen.

Here are the 2 screenshots of the Pi. One whithout anything but the Desktop running, one with glxgears running (window resized to about the double).
