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.

I've never actually seen an actual, genuine leadhine product, only ever counterfeits, remakes, knowckoffs, etc.

I'm not sure it's actually possible to puchase a real leadshine driver.

Is yours genuine?

Do you have a PC you can use, preferably with a parallel port or parallel port card?

That driver is really designed for a PC with a parallel port.

Also, it's only 3-axis.

XYZ, XZA, etc.

You can't have 4 axes with only a 3-axis driver.

Stupid Autodesk.

However, they'be pretty much cornered the CAM market.

They've bought up almost every competitor they ever had.

maslowcnc.github.io/MakerCAM-hosted/

FreeCAD?

carbide3d.com/carbidecreate/

All the "professional" CAM software is Autodesk.

If you think you can achieve high accuracy, go ahead and make it yourself.

But I personally wouldn't.

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 ?

I have a feeling the way I'm trying to wire my end and home min stops is the prob(use to 3d printers) but I redid the pnconfig using discover board and now the endstops don't stop me from turning the machin on in linuxcnc so I'm slowly getting there
