I think it will be difficult to meet all dependencies on Debian 10. Upgrade to Debian 12 Bookworm

Hi Tommy,

Yes, python related.

PyConfig_InitPythonConfig and PyConfig_SetString, are part of Python's new initialization APIs introduced in Python 3.8.

Try:
sudo apt-get update
sudo apt-get install python3 python3-dev python3-pip python3-venv

Hi,

Looks your sources.list is not ok.

$ sudo thunar

Then find and edit the ~/etc/apt/sources.list

# Fetch sources list.
$ sudo apt get update
# Check if source excists:
$ sudo apt-get install --dry-run ethercat-master

 

I have a problem when making round cavities or holes. In the axes corresponding to the angles 0 -180 and 90 -270 the dimensions are correct, but in the diagonals the dimensions are no longer correct, in the diagonal 45-225 the dimension is smaller and in the diagonal 135-315 the dimension is larger.

Hi Collins,

Today was a good day for coding. This morning still had a crash problem for the interpreter.
For the colors of the code i thought, RGB, red, green, blue.

Now the super imposed interpreter is running ok.

Added the realtime environment : base-thread & servo thread is loaded and running.

The servo-thread has now 3 motion components running. This is really cool.

libmotion_0.so -> produces motion for main interpreter (red)
libmotion_1.so -> produces motion for sub_0 interpreter (green)
libmotion_2.so -> produces motion for sub_1 interpreter (blue)

The idea is then to send the interpreter's gcode output to the motion components over the 1ms thread.
We do this over shared_memory.

Then we have to code the motion components. They will use the scurve and toolpath optimalisation as seen before.

The base thread has the libethercat.so component running soon.   This has ethercat auto configuration.

This is going to be a cool winter project.

There are a few questions, like what if sub_0 interpreter is a tool changer. The green tool cone is then not valid.
Depending on the machine configuration, the green and or blue cone must be replaced by something else?

I'll try to explain how the spindle-index-enable works.
This is the traditional syntax in hal to enable synchronization on index signal
linuxcnc.org/docs/html/examples/spindle...._synchronized_motion

net spindle-index-enable encoder.3.index-enable => spindle.0.index-enable

First look at what motion.spindle.M.index-enable says

spindle.M.index-enable I/O BIT
For correct operation of spindle synchronized moves,
this signal must be hooked to the index-enable pin
of the spindle encoder.

Then look at what the encoder's index-enable pin says
linuxcnc.org/docs/html/man/man9/encoder.9.html

encoder.N.index-enable bit i/o
When true, counts and position are reset to zero on the
next rising edge of Phase-Z. At the same time, index-enable
is reset to zero to indicate that the rising edge has occurred.

These three lines say a lot. This is the behavior the EtherCAT client tries to replicate.
index-enable is a I/O bit, that means read AND write variable. As mentioned, EtherCAT variables
are read OR write. The metalmusings_encoder component split index-enable in two variables
one read variable that forwards the value to the EtherCAT client, and one write variable
that when set will change index-enable, as specified above.

In the EaserCAT 3000 client, when Obj.IndexLatchEnable is set, i.e. when index-enable is set, it waits for the next Z-index interrupt, which then then zeroes the counters. This needs to be done exactly when the Z index happens, not any time afterwards. Because this happens in an ISR it communicates to the rest of EaserCAT with indexPulseFired variable. So in cb_get_inputs() when setting whether the index fired it will know that from this variable.
It is pretty indirect programming, but that is how I have been taught to communicate with ISRs.
Then it will set Obj.IndexHappened, which will go the the metalmusings_encoder component whioch will reset the i/o variable.

Not sure this clears things up, not so easy to write a good clear answer to this.

Hello

My turn to request some help.

I tried the mokutil stuff:sudo mokutil --import /var/lib/dkms/mok.pub
EFI variables are not supported on this system

sudo mokutil --sb-state
EFI variables are not supported on this system

I also tried the ecat.sh script from the other topic:

paul@mill:~/Downloads$ ls -l

Any idea of what should I do?

Thanks you in advance

Thanks a lot for your proposal so far !!
It's in good hands, as it is used for development for our open source community.

Sure.

Thanks! Greatly appreciated! I assume I can use a SPINx1 on one of those PWM/dir channels?

Hi,

apt sources list is set on local cd. This is my suggestion.
edit the sources.list to update from internet sources.

~/etc/apt/sources.list

Easy to use in terminal is :
sudo thunar

sudo apt get update // Fetch the sources list.

Then try it again.

What is the result of
sudo apt update
And
sudo apt upgrade
?

Hello

I have exactly the same issue on a brand new install with the iso from linuxcnc download section. I'm. Not able to update at all. Any idea?

Thank you

Ex corporate pc is cheaper, more powerful, easier to setup than either the 4 or 5.
