Hi David,
Thanks for the info. I'll take a look right away and compare it with my configuration.

Peter

the terminal emulator results are as follows:

Latency test value screen shot attached, ran with 10 GLXgear and one 4k movie for 2 hour.

As I am noway an expert of these parameters, are they ok?

And one thing I noticed, the monitor goes blank sometimes for a moment, probably power issue. Now can such momentary power issue to CPU and MESA card create problem? Or could there be any issue with software download (and installation) as I had such issue before.

















 

There is discussion about removing the 'sim.gscreen.silverdragon' simulation config in master as it fails on load with Gtk related errors on current debian bookworm installations as well as RIP installation of both 2.9.x and master.
So, if anybody has actually managed to run the 'sim.gscreen.silverdragon' simulation config in 2.9.x please drop a note. github.com/LinuxCNC/linuxcnc/issues/3094
Thanks

Hi,
i finally could upload it...i did it this time all in windows. I erased the chip and flashed the 1.0.0. And maybe the older python version did the trick. I don't know... No timeout and works like a charme. Thank you!

for 2.9.x you want these docs:
linuxcnc.org/docs/stable/html/de/gui/qtdragon.html

Hi Chris,
I don't know. It is an installation with the ISO from linuxcnc.org. LinuxCNC was version 2.9.2 and was upgraded to 2.9.3 during an update. I'll have to look up QtDragon-HD. Is there any indication of which version of QtDragon-HD is installed?

Peter

I am now using qtdragon with linuxcnc 2.10.0 and have ventured into the ngcgui programs. Arc1.ngc and arc2.ngc (arc2 calls arc1) are not adding tool compensation (g41, G42).
The solution is to remove the backslash from 4 lines 266-274 in arc1.ngc.
They should read as follows:-

The file is located in ~/linuxcnc/nc_files/ngcgui_lib
You will have to be root to edit this file. I.E. sudo nano arc1.ngc

How did you add the firmware to MesaCT?

Can anyone recommend a low-latency remote assistance software?

We usually use Teamviewer but you must be using an Xorg desktop not Wayland

Hi everybody, as the name suggests this is a guide for people wanting to install and start playing around with Riocore.
For those that don't know anything about Riocore you can read through the original thread :

www.forum.linuxcnc.org/18-computer/49142...d-on-fpga-ice40-ecp5

This guide is aimed at people that aren't linux guru's, that want to have a try at this awesome LinuxCNC software/hardware and that might struggle like I did...for weeks...to install it and get it going.

Credit to meister, the guy behind it all, he has done an impressive job of getting all this going.

Another credit to ColdTurkey, his idea of using the LinuxCNC live install to setup software/hardware in the Remora thread is what I based my approach on, this way everybody has the closest starting point possible.

This guide will focus on getting everything going for the Gowin Tang Nano FPGA, and meister's Tangoboard, once you have this going you can select other FPGA's and boards as you wish. You will most likely need to change the FPGA programming side of things with other FPGA's.

OK lets begin...
This is for a normal PC, I will have a look at a Raspberry Pi install sooner or later hopefully.
Download and install the latest live install of Linuxcnc, then open a terminal

sudo apt install git
open firefox, skip all start steps, start browsing, google search gowin eda
open page, (first link for me) create account, only email and password required
once logged in, select support, then Gowin EDA Home, then Download Gowin EDA
select software for Linux tab
select the one that says education, (click over to the right)
  (at the time of writing this it is the 7th option down)
open File system, navigate to Downloads, right click and select extract to
click on the little folder icon and select Home then extract
go to the folder in file system, right click rename folder to gowin
    its easier to type out later
open terminal, enter these one at a time :  
git clone github.com/multigcs/riocore.git
sudo apt install python3-pip
sudo apt install python3-yaml
sudo apt install python3-graphviz
sudo apt install openfpgaloader
sudo apt install python3-pyqtgraph

That last one takes a while to install

Now we setup the USB programming :
in terminal still,
cd gowin/Programmer/bin
once you are in that folder type and enter :
sudo ./Gowin_USB_Cable_Installer.sh
sudo make

reboot machine

open terminal

type and enter :
export PATH=$PATH:home/your_user_name/gowin/IDE/bin

in my case my user account is "me" so I type:

export PATH=$PATH:/home/me/gowin/IDE/bin
export PATH=$PATH:/home/me/riocore/bin

change to the riocore directory
cd riocore

now type
PYTHONPATH=. bin/rio-setup riocore/configs/Tangoboard/config.json

This should get you up and running, now there is lots to learn about setting up a machine but hopefully this will take the heartache out of starting.

Now things can be a little weird, I believe the Tang Nano needs to be plugged in at reboot, sometimes it won't flash properly, I cannot honestly say I have got it 100% sorted but if anybody finds a better solution we can edit this to suit.

Good luck
Russell.

Clone these 2 repos (or download az zip)
github.com/marcoreps/linuxcnc_leadshine_EL8
github.com/LinuxCNC

Clopy from the second these files in to a known directory (/home/cnc/linuxcnc-dev/emc/motion/) for example.
homing.c
homing.h
motion.h

from the first repo, edit the el8_homecomp file, and change the path to homing.c file, to where you saved your files.

compile the cia402.comp:
sudo homecomp --install cia402.comp

compile the el8_homecomp.comp:
sudo homecomp --install el8_homecomp.comp

edit your axis.ini (or whatever is your gui)
after the EMCMOT, paste this line:
HOMEMOD=el8_homecomp
 

I followed all the steps in this instruction.
 

So thats it. The rest is setting up the servos, and the internal homing in the drives. Without it, you can not use this process, since the servos not responding to homing request.

I had problems with this point.
I can't figure out yet which parameter in the servo I should change

The problem is that when the driver fails the red LED does not light up. On the other hand, if I disconnect the driver from the bob, the red LED does turn on. I am doing all the tests with a single driver and the only input I have free.

And in that case i would try to set Alarm level parameter. Maybe your AMP show foults in different way. In this case you have to simple invert Relay connection and joint.0.amp-fault-in

trav328 how or where can i find your setup files ?

you have to collect signals from all amplifiers via a relay and connect it to one input  of your Bob. As a bonus, I would connect LEDs to show who is in pain.
