Thanks for the response.

Once my machine is set-up correctly, I successfully use multiple Offsets to do jobs on the table.

I started this investigation of G10 'assuming' that it was used to set-up the machine without having to physically move it to the Home position.

So far, that assumption has been demonstrated to be false.

What does one do if the machine cannot be physically moved to its Home position ?
For example, a large job mounted prior to machine start-up, or a vice.

Note: I simulate physical table movement at start-up by operating the controls with steppers Off to the position measured by ruler.

NVIDIA proprietary drivers do not work with RT kernel and neither do new AMD drivers.
Most of the time NVIDIA cards will cause latency spikes and should not be used for machine control, but i have plenty of GTX1060 and GTX1070 that are usable with NOVEAU drivers, older ones will mess latency badly, and even the ones i have on some motherboards do cause issues, so it's a cr@p shoot.
First, fix the ethernet latency, disable power saving options in BIOS and hyperthreading and TPM and..., then we can see what still needs to be done.

Seems like wiring issue, hal and ini seem fine, looked twice, but i do wear glasses ...

I don't think the video is an issue as it would show up in the generic latency tests.
 

The hal/ini files seem right

Short or other error in the cabling?

If you have the latest mesaflash you can:

mesaflash --device ethernet --addr 10.10.10.10 --dbname1 hdr26 --readhmid

(if you want the 26 pin IDC wire numbers)

If things still don't work, you might disconnect your cable
and check if the expected 7I92TF DIR pins change state
when jogging in different directions.
 

I have a nvidia 610 video card, should I replace nouveau with the proprietary nvidia driver? (I already did it in theory)

I got this same error when working on the qt version (based on python2 stuff).
IIRC I removed the offending entry and didn't notice a problem (but I don't use it)
IIRC I tested a python2 original version and didn't get the error - so my guess is the parsing library is more picky by default now.
I don't know enough about the saving format to make a definitive decision.

Hello Everyone

I had a great experience converting the EC300 board with Remora firmware and then using it for my CNC milling machine. I have decided to put my learning into good use and start selling EC300 boards on Ebay. If you are based in the UK and looking for a board for yourself, it is your lucky day

Installation Instructions

1. Download the necessary files from GitHub:
   • github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic (copy to LinuxCNC/Configs)
   • github.com/scottalford75/Remora-RT1052-c.../LinuxCNC/components (copy to LinuxCNC)
     
2. Install Remora components by running in Terminal:sudo halcompile –install LinuxCNC/components/remora-eth-3.0.c
   sudo halcompile –install LinuxCNC/components/nvmpg.c
3. Configure Ethernet:
   • The EC300 IP address is 10.10.10.10. Set your LinuxCNC PC to a static IP such as 10.10.10.11.
   • Edit your network settings by running:
     sudo nano /etc/network/interfaces
   • Add at the end of the file:interface [your interface name, e.g., enp0s25 or eth0]
     static ip_address=10.10.10.11/24
   • Save and exit (CTRL+X, then Y, then Enter), then reboot your PC.
   • Confirm IP address with:
     ip addr
     
4. Install tftpy module for uploading configuration files:
   • Open Terminal and navigate to a folder (suggested: LinuxCNC folder).
   • Create a Python virtual environment:
     python3 -m venv .venv
   • Activate the environment:
     source .venv/bin/activate
   • Install tftpy:
     pip install tftpy
   • To exit the environment later:
     deactivate
     
5. Configure Inputs/Outputs:
   • Download the EC300 configuration file:  EC300 Config File
   • Copy it into LinuxCNC/configs/remora-rt1052-basic.
   • Ignore or delete the EC500 configuration file in the same folder.
     
6. Upload the configuration file:
   • Power up the EC300 and connect it via Ethernet.
   • Run the upload script(in virtual environment):
     python3 LinuxCNC/configs/remora-rt1052-basic/upload_config.py configs/remora-rt1052-basic/ec300-rt1052.txt
     
7. The basic setup is complete! Example HAL and INI files are available in the remora-rt1052-basic folder.

That worked but now I get a new error:

./ethercat.hal:50: Pin 'lcec.0.0.cia-statusword' does not exist

this occurs at the following line:

net x-statusword lcec.0.0.cia-statusword => cia402.0.statusword

I clearly have an error here but I don't know where to look to correct the problem

I don't exactly know how it would, but there could be an explanation if the override is constantly dithering. Maybe as the python is updating the override it misses a message back from the probe routine. The probe routine and the screen sends messages back and forth at start and finish of probing.

If you run in debug mode (DISPLAY = qtvcp -d qtdragon) and run linuxcnc from a terminal, we maybe able to see the difference in commands

There are some instructions here:

I need search and compile him or only apt-get?

the answer is simple,
GRBL,... is a firmware for CNC milling machines, laser cutters and the like.

LinuxCNC is a highly configurable motion control platform,
it can synchronize all kinds of input and output devices,
also from external not self-controlled movements.

It can handle all kinds of actuators, not only step/dir or RC servos. It can handle all kinds of protocols like Ethercat, CAN, Modbus, .... and even mixed.

It can handle
all kinds of inputs, glass scales, encoders, camera images, .....

It also doesn't need gCode as input, that's just another module in the chain


So if you want to operate a simple hobby CNC, you are well served with GRBL and so on, for everything else LinuxCNC is the best choice.

rtt min/avg/max/mdev = 0.158/0.255/4.918/0.225 ms

Yeah, ~ 5 ms will be an issue

What is the Ethernet hardware?

If Realtek you likely need to install the DKMS driver

Please , i want understand :

If remain refclocksynccycles = -1 in xml file, can have some problem on real machine ?
