I know it's a step to include motion/motmod.
Linuxcnc should be in charge of the movements, that's the whole point.
Motion should do the the homing, and control it (as best as it can).
Motion should also make possible to switch an joint from axis to spindle. 
Or make possible to use EtherCAT probing.
We don't need to invent crazy situations, but the common ones.

What we do now with these components, homecomp, etc and I have done one myself
for Profile Velocity for spindle, is to have the component decouple the real position from motion
and then re-couple it. The right thing to do would be to have motion handle all motions.

I don't expect you to go that route. I just raise the thought.

Quick progress update on this project.

The CiA402 semantic layer has now been fully validated in pure HAL + AXIS SIM.

Current validated behavior:

- Clean separation between PDS state machine and opmode modules
- Deterministic controlword composition (no 6040 ambiguity)
- 6060/6061 handshake confirmed
- Mask/value based statusword evaluation
- Operation Enabled gating exposed as a hard industrial gate
- Fault injection during active homing:
-> immediate abort
-> op-enabled cleared
-> no false “done”
-> clean fault-reset return to OE

All of this is transport-agnostic and does not depend on LCEC or EtherCAT internals.

The next planned step is extending this architecture to dual-axis gantry / squaring validation in SIM, keeping CiA402 logic fully modular.

At this stage I do not have EtherCAT hardware available.
If someone with LCEC + CiA402 hardware would be willing to test the modular stack on real drives, I can prepare:

- Clean HAL example configuration
- Minimal README
- Reproducible test steps
- Fault and homing test scenarios

The goal is to validate that the semantic layer behaves identically when replacing the stub with real PDOs.

Feedback on the gantry direction is also welcome before I proceed further.

Ja, war direkt mit den Glasmaßstäben, weil ich sowieso den Umbau auf 3-Achs-CNC vorhatte.
Hast du den Original-Vorschubmotor/Scheibenläufer schon gegen einen Servo getauscht? Der Scheibenläufer hat nur einen Tacho und keinen Encoder.
Falls du schon einen Servo hast, sollte das auch via Servo-Encoder machbar sein. Das Nachregeln könnte man allerdings durch entsprechende Reglereinsteellungen auch verhindern (Deadband). Gibt zwar bestimmt einiges an Umkehrspiel durch die ganzen Getriebe, weiß aber nicht, ob das bei den Trapezspindeln noch groß ins Gewicht fällt.

Here it seems to work as expected.
Could you describe the error, or attach a screenshot?

Ich habe es gerade auf der Arbeit probiert, auf einem anderen PC, und auch dort kann ich in die Themen nichts mehr antworten, ohne die Fehlermeldung zu erhalten.
Warum kann ich das in diesen Themen?

und

Ich habe so etwas nicht. Und bei mir funktionieren zwei Browser nicht. Handy und Tablet gehen auch nicht.  

 

I am using a milling maschine, i am New to linuxcnc and the editing of files , ist that possibly the problem that i User the default files ?

I got it work with a own component to make 1 move from position to position forwaes with lock backward and reduce pwm.

But the turret can only travel to next position in forward.

If i am on tool 5 and i want tool 1.. i need 2 times the move.
Is it possible to do this in the component with a abs function?

what i mean... i must handle the rollover=

presenttoolslots 6
currenttool is 6
calledtool is 1
Turretmoves = calledtool - currenttool = -5
Commandedmoves= presenttoolslots - (abs) turretmoves

next step is the to count every move.
moved = i++
if moved == commandedmoves
toolchange done

Sounds ok?!

I do the coordination of the forward and backward stuff with 2 time delays. On the end i set the pwm value lower to lock agoinst the pawl with lower current to not blow the dc motor.




Thanks

Based on the data provided, if the motor is a permanent magnet type, it is likely in the range of approximately 7.5 kW (or max 11 kW)

From the peak data shared, I estimate that the motor’s rated current at stall torque would be around 50A. Accordingly, you may need to consider a universal drive rated at approximately 50A.. This will be around 22kw

Can you verify whether the motor nameplate specifies a rated voltage 400V, or is this value being assumed based on the drive input power?

Got my first cuts made with it today, took a while to get the gcode to work correctly with qt plasma c
We also added a image to dxf function, still needs some work but its a start. 
I added a kerf width calculation wizard... cut out a test piece input the actual cut size vs the wanted cut size and it calculates what your kerf width is spoused to be. I did a install on a friends computer and some of the install seems broken, need to make it more shareable if anyone else wants to easily use it. Not to shabby tho for only being 2 weeks into the project part time.

i have here a l298n modul and a mesa 7i92 with bitfile adjusted to have pwm and 2 gpios for setting direction.

You could start by having a look at the "etch a sketch" config included with LinuxCNC, it is for parallel port so needs changing pin names to Mesa, and it is for L298.
Probably doing some timing stuff in hal using timedelay and/or oneshot and maybe flip-flop ....

Reading something today. Maybe try using smp affinity to lock the USB interrupt to  Core1 (away from core 0 housekeeping) and assuming > 2 cores. You can find the interrupt by
cat /proc/interrupts | grep -i usb

Then follow one of the many posts about cpu affinity for networking. Just remember you need to reset this on every boot.
