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. 

Start here and continue on

Edit card name accordingly.

And there's this one:

www.apsx.com/apsx-nano-cnc-swiss-lathe

Nowhere do they explicitly mention LCNC.  It runs on "ASPX CNC software."

And yet...

All the g-codes, M-codes, etc. are identical.  Post processor is minor edit of the LCNC post.

Not sus at all.

Hello, great job with porting remora to these boards.
I went through a lot of post on this forum thread, but I'm not able to find the schematics for the EC500. Does anyone have a reverse engineering version of the PCB schematics? Thanks!

It's not a issue with Intel MACs
If you disable IRQ coalescing
and pin IRQs, You get pretty decent
performance.

For example on this HP8300 I have been running a test on a 7I76EU
with a 3 KHz servo thread for about 3 days while using the PC for general
web browsing, email etc and have not had any issues.
(CPU frequency is 2.9 GHz and times are in CPU clocks)

@PCW who would be the person group best suited to fixing it, and do they know about it? is this a linuxcnc thing or a debian thing?
 
Honestly its a Linux thing (broken driver) but would be easier to fix in a non debian compliant ISO
Ultimately it should get fixed in the kernel driver so the proprietary Realtek driver is not needed.

Interesting, would it help the intel adapter performance as well? bring it back to the 4.9 kernel day performance?  i miss those days...lol

The matrix_kb component can work with a 7I73 or any I/O device
that has input and output bits. With a 7I73, it converts a scan code byte
to individual key outputs. With a general I/O device it provides the row and column
output and input bits and converts them to individual key outputs.

Are you sure the 7I93 I/O bits are set in the proper directions?
 

it does have a speed display, i guess i could try to check the scales for both encoder and step scale. I will report back once i wake up, ty guys your help is truly appreciated!!

Hi Evrybody
I'm trying to write a post-processor to convert APT file (ISO4343) to ngc to get path working on LinuxCNC. A long time ago, unfortunaltly, I have thrown away my course of PP writing (it was in the early 90's for CATIA v3 with FORTRAN). I have not practice since this time.
I'm slowly learning Python for this.
Is anyone have an idea how-to ? APT language ? How to structure program ? ...

Hello,

I've tried to set up matrix_kb with 7i93 using 3x3 matrix at a first time but it reads all buttons in one column as pressed (of course I press only one button).
I've tried to use diodes to separate buttons without success.
I see but doesn't clearly understood that matrix_kb is mainly designed for 7i73, is this correct?
Should it work with 7i93 or must I go with 7i73? 7i73 for me wouldn't be a convenient solution because my 7i95's SS ports are configured as SSI interfaces for ABS encoders so it would be difficult to connect an additional 7i73 to it.
Any other ideas/workaround to be able to connect about 30 buttons to Linuxcnc without using 30 inputs?

Thanks a lot.
Tamas
 

Raspberry Pi 5 support

As you may have seen in the rp1lib thread, I've been working on RPi 5 SPI support for LinuxCNC. It's ready for some testing and feedback!

github.com/scottalford75/Remora/tree/mai...omponents/Remora-spi

This version of the Remora component will detect which Raspberry Pi version it is running on and load the appropriate SPI and GPIO drivers, BCM2835 or rp1lib.

For the Raspberry Pi 5 there is future features that will need to be added to the loadrt command line:

1. The RPi 5 has 5 SPI instances available on the header
2. Each SPI instance has a choice of 2 - 4 chip select GPIO pins
3. Different method to configure frequency

For those that wish to test, remember this is a Beta version. Bugs may still be present.
 

Does the servo drive have a speed display?
If not, Do you have something to check the spindle RPM?
If not, do you have an arduino and a photo resistor or optical sensor?
All these measuring should be done with no spindle feedback in hal as not to mess up the readings when commanded at a certain speed.
-
The encoder feedback RPM is easy to find manually, set the hal show to show the raw counts from the spindle and rotate the spindle by hand 1 full turn, adjust the scale accordingly.
-
This is untested, but setting the spindle as an axis and the output scale to 1 and checking how many mm it takes for a full rotation by using MDI or just jogging, would yield the actual scale.
