Can someone explain how squaring is handled on dual motor linear axis?

Category: CNC Machines

Squaring the gantry is done during homing and relies on the HOME_OFFSET for alignment.
It is super easy to do if you read the most important part of the documents, homing configuration
linuxcnc.org/docs/stable/html/config/ini-homing.html
Except you will probably need to read this page 3 to 10 times....

General Questions about using ethercat

Category: EtherCAT

Thanks for the help, it loaded after changing lcec name to D1 and D2, and after I commented out several lines.

ethercat slaves shows both are on OP mode, but I am sure I don't currently have enough pins defined for motion control.

I need to work out what those line problems are, some are just not defined and some are type mismatch, but I may be able to work that out.

fresh install issue with 2.9.4

Category: Installing LinuxCNC

This is a really annoying bug from Debian. This fixes it.
sudo apt update 
sudo dpkg -P raspi-firmware
sudo apt dist-upgrade

This was in Debian 12.1 their initial Bookworm Release and fixed in Debian 12.2 a month or so later.
But they never updated the code in thie Debian Live installer. Debian must have used a fork of this to build their images and never bothered to correct the Debian Live system.
Its not something we can fix in our ISO. We did tell the builder to exclude it and it works but as soon as you do an apt upgrade, it comes back.
