Can you share any solution for fix this error about DKMS and don't need  to reinstall with .ISO ?


 

Refer here. Please restrict this thread to Ethercat installation only

yes

I was missing the start


after adding start it is working

Now I will read how to make soft button

Thanks

Hi guys,

Tonight i did a test on the ethercat production machine, i brought a pc for the machine, pre installed linuxcnc and halcore on it.
This pc was already tested ok on the ethercat test board.

At the machine, after a while i came to the conclusion that one of the lcec output module's was broken, the stepper dir module.
altough it's brand new.  So maybe it is thanks to Stuxnet that i had so much trouble this week.

I had to drive to home again, and get a other lcec module. Then replaced it, and it worked.
But then the 24v input's where a problem. The input lights are burning on the module, but in halview, no signal is incoming.
So that's a problem i still have to solve. It was no problem for testing the machine altough.

Ok i made a few video's to show you.

The machine is never used before, and is software limited to 15000mm/min, it can run up to about 19000mm/min.
The machine has 2 x-axis motors, 1 for y, 1 for z. The machine setup is backslash free.
At the time it was configured with steppers. Nowaday's i think i would use servo's.

The machine in the workshop, the workshop i a collection of items, you see an old car in the background.
 

First video, running halcore.


Surface test.



Lcevette file milling, tiny product.

That is exactly what I did to solve the issue. The interesting part is that this behavior become apparent only after I upgraded my PC and changed my Mesa 5i25(PCI) with 7I92TF(ethernet). 

I'm not sure about halrun but the thread component needs
a start command when run from halcmd
 

Sorry... another newb question.

I have written and understand the need for a reverse transformation that converts a desired X,Y location to joint rotations (I have a simple 2-axis system).

We are running in open loop so there is no feedback.

Is there a reason LinuxCNC needs the "forward transformation" (which if I understand correctly, would convert a known joint rotation to LinuxCNC to a specific X,Y location. in an open loop system, what purpose does having both a forward and reverse transformation in your kinematics file do?

Rod,

Also a newby here - trying to run LinuxCNC on a Raspberry pi4 and use the GPIO but getting an error that we don't have hal_pi_gpio module. Where do we find this? I've seen reference to this being part of Machinekit. Do we need to replace our existing LinuxCNC install with Machinekit or can we simply install the necessary hal_pi_gpio modules to get the GPIO running with our Pi4?

I want to change the state of pin 17 on my breakout board. At this stage, I dont want any GUI involved.

I want to change the state of pin 17 by halrun command

halcmd: setp parport.0.pin-17-out 1

the hal file name secondhal.hal,      then I issue 
halrun -I -f secondhal.hal

---

loadrt threads name1=base-thread fp1=0 period1=50000 name2=servo-thread period2=1000000
loadrt hal_parport cfg="0 out"
setp parport.0.reset-time 5000
1addf parport.0.read base-thread
addf parport.0.write base-thread
addf parport.0.reset base-thread

---

but no change to bob pin 17
Can anyone help?



Good day

Development Board Design Based on ESP32-P4 RISC-V SoC with Ethernet

linuxgizmos.com/olimex-showcases-develom...esp32-p4-risc-v-soc/

$5 Raspberry Pi Pico 2 with RP2350 Microcontroller

linuxgizmos.com/introducing-the-5-raspbe...350-microcontroller/

Now we need them to combine the newer 2350 with the W5500.

Make a new and clean installation on another computer, do not touch the existing computer. If you can run it on a new computer, reinstall it on your existing computer.

If spindle at speed signal goes false during a feed move, motion does not stop. It will only stop at the end of the current move,before the next move.

We have 3 deckels, all with gearboxes that are automated. I always invert the spindle at speed signal and connect it to motion.feed-inhibit to deal with this issue

You may be right about the timing because I tested the code below and works as expected, but I had to put G4 after the speed line.

Hi , at all.
in many example ethercat.xml configuration files, the values ​​of refClockSyncCycles are different.
Sometimes -1 , sometimes 1 , sometimes 5 .
If you use a servo period in the ini file of 1 ms , what is the correct value to use ?
Keeping in mind that appTimePeriod is 1000000

Thanks

I was shy to ask where those shift arrays came from. So glad you've explained.

I hope for lightnings, thunder, heavy rain and a dozen typhoons all of Sunday. I'll cave under and get it done. Thanks a-mil again Oliver.
