Great thank you for your support.
How do you debug in your platformio project?

I will create my usbject once I made some progress
Meanwhile I remove pin SYNC0 and SYNC1 but its not working anymore with the original project, i will need to adapt with yours 

My latest video is 28 minutes of pure gold for those needing to minimize network and system latency on Debian Bookworm and Trixie

The info assembled here is scattered and its never been available in one place. Also, many articles on the internet refer to obsolete applications no longer in Debian Bookworm or Trixie (for good reasons).

This video covers how to:
1. Configure the GRUB kernel settings
2.  CPU Governor set to performance
3. NIC coalescence disabled for Intel network cards
4. Network driver correctly installed and configured
5. CPU core isolated for LinuxCNC Real time process.
6. IRQ for Network card identified and set to Isolated core
7. Outlines why irqbalance should NOT be installed

Also, whilst kernel documentation states energy efficient ethernet is disabled by default but this is not always the case. Whilst some NIC's allow it to be disabled with GRUB parameters, there is no standard so different network interfaces need different treatment with hard to find parameters. We show how to create a service that disabled all NIC's. This requires a configuration file attached (to be used in conjunction with the video) that I have attached as a convenience here.

This has been one of the hardest LinucCNC tutorials I have ever put together. Please provide feedback here and as comments on the Youtube video. Enjoy!

 

Sure, let's do that.

Best to start your own thread I guess.
I propose you do it in two steps
1. get encoder working
2. ethercat.
 

Hello @Hakan
I received the board and it worked smoothly with the firmware inside.
However I have a lot of issue to edit, mainly I think due to chinese chars that are not converted correctly.

The TIM2 CH1 and CH2 are quite easily accessible. Do you want to help/assist me in order to build the new firmware ?

I think i can take you firmware and edit it, I feel almost capable, however regarding the eeprom etc I'm totally lost.

Maybe we can try step by step?

Anyone?
Probably got terrified of the long (and not very useful) list.
The list should be something like:
-e-stop chain
-limit and home switches (with sensor input relays for full isolation)
-extreme limit switches for DC brushed motor machines (to prevent mayhem in case of runaway)
-Mesa boards wiring to drives, input relays, output relays, and maybe MPG
-power section
-list of connectors and pinouts
-...
Thing is, we can not make a schematics for you without having every exact detail about your machine setup and wiring, that is something you have to provide.
Or do you want us to come up with the wiring and base your machine on that?
-
Personally, i write things on paper and take pictures of those papers for archiving, while the papers go with the machine.

Oh, that works great, thank you very much. I even made a small function that checks the active HAL pin against the widget every time the encoder signals, but your method is much more elegant.

New question: how to connect a button to a HAL pin? I want to add an MPG on/off button. I created a HAL pin in the handler file and created IndicatedPushButton. In the button properties, I added HAL.set_p(’mpg.mpg-enable’,’1’) to true_python_cmd_string. But I got an error:

  File "<string>", line 1
    HAL.set_p(’mpg.mpg-enable’,’1’)
              ^
SyntaxError: invalid character '’' (U+2019)

Can you find anyone near you that knows a bit about wiring?
That would be very helpful.

The same pins used on RPI are on the W5500, those are the SPI pins so the wiring is the same.
Just check the pin naming.

Download the official LinuxCNC ISO, write to USB, use that USB to boot the PC (any PC) and use it in LIVE mode to view and test gcode using any of the included SIM configs.

Try adding this
linuxcnc.org/docs/2.9/html/man/man9/timedelay.9.html
to amp.fault input pin.

Dear author , please share the result. Unfortunately, I have the same problem and cannot find a solution.

I really could use some help trying to figured out how to setup a delay for amp.joint when I enable the machine i get a instant error from joint.amp using clearpath SD HLFB  , from what ive read i need to add a delay for it.But the problem is ive tried but no luck please someone show me a confing to get me started.

Thanks 

I did not get a working stepper configuration out of MesaCT with a 7i76eu. I have posted the output and my working config here forum.linuxcnc.org/configuration-tools/5...erated-configuration

The output was supposed to be on the 02 stepper but it was connected to the 00 stepper. The feedback loop was not closed and it was not set to be in velocity mode. Look at the two configurations.

Raspberry Pi 4B running Gmoccapy 4.9.4 without any significant issues on a 3-axis turret mill.

CamBam used to produce 3D MOPs for cast iron model locomotive wheels.
Camotics and NCViewer used to simulate the GCode files produced. 

But, as we all know, issues do arise that need review.

NCViewer displays the GCode file and a 3D representation of the paths.
It includes an option that shows each GCode data point in the 3D display as a GCode line is highlighted.
The reverse does not work, selecting a data point does not highlight the equivalent GCode line.
 
Looking for suggestions on how to identify a GCode line when a path/point is selected on a 3D path display.

Here's at least a first attempt:
