This is what i see and where the problem code accurs , could be something Wrangler with my linuxcnc or Couleur you give me some advise ?   

Hi JRC,Thanks for sharing your spindle configuration — it was really helpful. I’ve also replaced the original spindle motor with a 1000W servo from StepperOnline, and I’m  pleased with how it’s performing so far - machine has its limitations but for aluminium it seems good so far. I’ve nearly completed my enclosures; I just need to install a  coolant system and add the chip tray and filtration underneath to separate the swarf properly.I’m running the Probe Basic interface as well, which I find very intuitive and easy to use.I have the ATC fitted to my machine but haven’t configured it yet. Do you have an ATC installed on yours? If so, would you be willing to share your configuration files (INI, HAL, etc.)? That would be a huge help.Also, I’d really appreciate a bit more detail on the cylinders you’re using to counterbalance the spindle weight.I’m currently designing a 3D-printed cover for the ATC and would be happy to share it once it’s finished.Thanks again Will 
 


 

Standard vanilla Gmoccapy 2.9.4, 3-axis turret mill, no internet connection,
Has operated fine, no problems, no faults, for quite some time,

Now it powers up with a blue screen devoid of icons,
Can still launch with/Applications/Accessories/LinuxCNC/drop-down-dialog-box/Gmoccapy/.

Web search tells me the absence of desktop icons is normal for Debian 12 Gnome desktop.
Also found a Gnome extension, "desktop-icons-ng", that can be applied to add the icons.

Will I break something if I attempt to apply this extension ?

Is there a better way ?

Thanks,
John.

You are right, the encoders are absolute and have batteries. Perhaps, the homing may be needed for squaring the gantry.

I changed all the cables with CAT6 and there are no loops. Attached are the terminal outputs for "ethercat master", "ethercat slaves" and "sudo dmesg". The synchronization errors seem to be disappeared. There is still some errors but I am not sure if they influence the EtherCAT synchronization.

When I try to execute "dmesg | grep ethercat" it does not output anything, just moves to a new row in the terminal.

EDIT 1: After I ran LinuxCNC and executed "sudo dmesg", it showed a warning that says 'Slave did not sync after 5000ms'. Attaches is a new file - dmesg_new.txt. It contains the warning for synchronization.

EDIT 2: Something weird happens to my system. After playing with LinuxCNC with different configuration, the same syncronization error appears again. It seems that the cable did not help. Attached is the lates "sudo dmesg" output - dmesg_last.txt
 

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?

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?
