Yes the kinematic model has to be written in C (or as .comp and then converted using halcompile )

ok some info for anyone instrested

turns out the gs20 has a gs2 compatibility mode that turns it in to a gs2 drive

Hi all, I am following this method to install linuxcnc and ethercat from source and then I am not very clear about the process behind it, is there any way I can download and configure the connection using cia-402 or can I just configure the hal file to connect.
I hope to get help from all of you.
Sincerely appreciate it.

Ethercat build from source - full instructions - LinuxCNC

Hi everyone, does the kinematics have to be written in C language? Can I write my own kinematics in C++ or Python?

Work ok

No, it's not.  I'm not bashing the machine, just the fact that they're obscuring the fact that the software is LCNC.

However, two things are crippling the lathe:

Clearpath servo for the spindle with no separate encoder - there's no index output signal.  Which means you have to 'home' the C-axis and do all milling/indexing operations in one go because you can't re-home to the same position after taking it out of C-axis mode.

And the 1/2" diameter limitation is a killer.

That lathe, with a spindle encoder (or servo with index output) and 1" spindle would be pretty sweet.

And if they could beg/borrow/steal the pneumatic collet closer from the Sherline, they could have a REAL swiss that takes stock longer than a foot.

One closer on the spindle, one on the guide bushing frame, and you could feed barstock of (mostly) unlimited length without an expensive bar-feeder.

Oh, and there's this...

 

First, test withIf that is still bad, see if you can set the package power limit in BIOS to 0 for both sustained and burst mode,
Then try disabling WLAN it can cause huge latency spikes on some of those NUC's

Yes and yes.

I assume the machine configs define things like:

- number of axes
- stepper motor count per axis
- axis limit switches
- spindle functionality: fwd/rev, variable speed, output signal (0v - 10v, etc),
- estop functionality

…and so forth. Maybe they also define your motion control board and any daughter boards too?

Hi, I'm new here.

I downloaded recent LinuxCNC image
　　LinuxCNC 2.9.3 Debian 12 Bookworm PREEMPT-RT ISO

and I'm trying to setup to INTEL NUC7 (Pentium J5005 4core /8GB MEM + SSD).

I've read many thread on this forum and  I've configured BIOS and GRUB.

I got this big latency as a result .  (latency.png)
What am I missing ?

Please help me solve this big latency.


What I did are
1) I added GRUB.
isolcpus=1,2,3 intel_idle.max_cstate=0 processor.max_cstate=0 idle=poll

2) I configured BIOS (screenshots)
(biosN.png)

Thank you.
 

NTP is ok, but might cause occasional latency warnings.
Start LinuxCNC and choose ant of the SIM configs, then close, then open again and choose a different one, play around and test as much as you like.
It does everything in sim as if it is a real machine, so very good for learning.

An update:

Ordered and installed a 500Gb SSD to replace the128GB SSD in my industrial PC (IPC).

I then retried the install from my bootable flash drive with the Debian/LinuxCNC install iso.

It again had the error trying to mount the iso on the USB drive so I did as described above…removed the USB drive, waited 15 seconds, re-inserted the USB drive, waited another 15 seconds, and selected the “Try again” option.

This time it mounted the iso on the USB drive successfully and continued with the install.

I went with the suggested partitions and sizes. However, it created a 1Gb swap partition and I had planned to make this at least 4Gb (since the IPC has 4Gb of memory). Oh well, hopefully 1Gb is plenty.

Remainder of install went off without a hitch. Rebooted from the fresh install on the new SSD and Dorian is up & running. Added a USB WiFi stick and loaded the drivers for it and now WiFi is working.

Powered off and moved the IPC upstairs where I only have a WiFi internet access. WiFi connected fine, but date shifted back to a day in June 2024…so I couldn’t get a secure (https) connection to any online web page.

So I googled configuring NTP for a WiFi connection, issued the NTP install command, and after installing I looked up and date/time were set correctly…and now https works fine for connecting to online web pages.

I’m a Linux newbie so happy to get this install working. Hopefully there is no conflict between NTP & LinuxCNC, anyone know?

I started LinuxCNC to take a look around. It immediately asked me to load a machine configuration so I just closed it as I have no idea which one to select.

Now it’s time to read LinuxCNC documentation…

From their PDF:
And lower on that document, at the "plot tab" is Gremlin (the LinuxCNC visualization screen, not the small monsters from the movie )
Last page, board with parallel port, oh yes!
Still the price is not astronomical.

When I take the gpu out it starts to load debian, then the screen goes black. It was showing visuals perfectly fine before. The TV I'm using now isn't showing the resolution error, at first I was using a vga dell monitor, and that was showing the error.
