Unfortunately, the test quickly shows why it is not a good idea to do something like this:
This is why USB is not suitable for real-time applications, as there is no guarantee that all data will be available within a certain time frame.

But my actual goal is to run the whole thing on the Raspberry via serial port, using RS422.

Here are the Hal and Ini files

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


 

I currently have a Lichuan model OL57E-4A 4-axis drive and a Stepperonline model A6-750EC 750 watt servo drive set up on the workbench for testing, I can connect homing and limit switches without too much trouble.
Both are LCEC + CiA402.
The Lichuan manual is available here:  git.gitcoding.net/nwe/lcec_4x_stepper/src/branch/main/manual
The Stepperonline manual is  here .

I'd be willing to test drive your config. It might be a couple days till I find time.

I would agree with Tom here, that there's something basic wrong with the hal  or ini files.

(my guess would be no position feedback connection from the steppgens)

I think I need to apologise, I'm currently testing a working serial/USB setup.
Not simple IO, 1kHz loop 3-axis stepper real-time control.
But I can't quite believe it yet, still have a lot to test.

I actually wanted to try building something for the RPI serial port, small and cheap, but for development I have it on the PC with USB/serial, and the bloody thing works.

Norbert,
Was the HAL pin for 'manual tool change confirmation dialog' ever implemented ?
I'm in the process of changing from par ports to mesa 7i92 and moving the PC out of the machine cabinet, as such my keyboard hack for a physical button on the control panel to press the 'Enter' key is no longer practical and with the larger amounts of i/p pins on the mesa card I would like to hook the physical button to a mesa gpio i/p pin and use that to clear the gmoccapy tool change dialog popup

now using 2.9.8 latest build

No because i have no feedback! Its only a dc motor and a disc that rotats in one direction and if you drive backward it looks against a pawl.

Here the mechanism

 


The dc motor drives a planetary gear.. the gear drives a wormgear.. the wormgear rotate the disc where the tools are mounted.


do you have a better solution without any feedback?
its not a issue to drive it to tool one and set it as tool 1.

i had years before mounted a stepper and done it with O Codes.. but the dc motor which was original used is bettee because it hold against the pawl. With stepper there is small small movement on the tool because its not holded against the pawl like the dc motor it does.

 

dmesg_new looks better.
However, your vid and pid are incorrect.
They are from Stepperonline A6.
You must enter those from your servos.
vid according to manufacturer xml: 00000eff
pid: 0d3e0001 (not sure)

Note:
please use: dmesg | grep ethercat as root
sudo su
password
dmesg | grep ethercat
that's conspicuous
EtherCAT ERROR 0-3: AL status message 0x001A: "Synchronization error".

Are you using the "carousel" component, or any other, or python remap for the tool changer?

Today morning still did not work for me, now evening and it works with Dark Reader active, so try again and let us know if it works.

The forum server is being backed up and upgraded, but for now there are no issues i can see.

set the HOME_search/latch/final velocities to something really, really slow, that way you can see what part of the sequence is causing the issue while homing.

upload the hal and ini files here so we can have a look.

i have found the problem , the problem was the sentence in the RS274NGC part :
[RS274NGC]
RS274NGC_STARTUP_CODE = G17 G21 G40 G43H0 G54 G64P0.005 G80 G90 G94 G97 M5 M9
# required NativeCAM item : PARAMETER_FILE = linuxcnc.var   <=HERE WAS THE FAULT I HAD WRITTEN THIS BUT THERE SHULD BE THE PLACE WHERE THE DATA SHULD BE => /Usr/linuxcnc/MY_CONFIG/........
SUBROUTINE_PATH = ncam/my-stuff:ncam/lib/mill:ncam/lib/utilities

Ten years ago I mounted a 5i20 on a friend's lathe. I remember we used all four ports because he wanted to use the original switches for feedrate and other things. Now he'd like a spare board in case of failure. What can I use with four ports?
