Hello everyone,

I'm a noob when it comes to Linux CNC. I currently have some Leadshine L8 servo drives (identical to EL8?) and I am trying to set up Linux CNC. I am using a raspberry pi 5 and installed the "LinuxCNC 2.9.4 Raspberry Pi 5 OS based on Debian Bookworm Raspberry Pi 5 Uspace" iso

So far, i have :
-Followed Rodw's post on installing Linux CNC from repositories
-Copied the Github repository by Marco Reps
-Compiled cia402.comp, el8_homecomp.comp, and always_homed.comp

Now i need to configure the hal, ini, and ethercat-conf.xml files and the files from Marco Reps repo looks overwehlmingly complex.

Could anyone help me figure out what are the basics needed to launch Linux CNC and understanding more what the content of those files mean and what do I need to modify.

I have used AutoCAD V13, Catia V4 and V5, Inventor, and Onshape in the past. I have been using Freecad for a while now. For simple stuff I find it just as good as any CAD program, once you become more rigorous with your use of reference plans rather then sketching on existing geometry.

With the castings I am drawing up for my antique motorbike engine project, where everything has draft angles and fillets,  I am definitely hitting the limits of it's filleting engine. I normally end up deleting my extrudes, and fillets multiple times, and changing the order I do things, and sometimes find an order which leads to most of the fillets I need. Luckily the time consuming part is the sketches, so there is not too much pain involved in backing up on extrudes and fillets, as the sketches get reused.

There is some issue with MacOS's latest release 15.4 which breaks access to numpy, which the CAM workbench needs. There is a workaround which works for some, but didn't for me.

There is something odd with your installation.
I just tried myself to "apt remove ethercat-master ethercat-dkms" followed by "apt install ethercat-master ethercat-dkms" and it worked just fine.
I do not get the "tainted kernel" message.
Can it be that you have compiled the ethercat master yourself at one point? And that the runnning ethercat master is looking for ec_generic in a place where it isn't?
It's a bit of guesswork and searching now.
Can you the command "sudo service ethercat status" and compare the ouput with mine?
 

Edit. Can you also repeat the search for ec_generic, but this time search for ec_master, in the same way?

Edit 2. No need to search. Instead show the output of the command "sudo modinfo ec_master", especially the first filename line.

I would first take a look at:

linuxcnc.org/docs/html/config/ini-homing.html

You can share limit/home switches

It seems to me that rather than a center limit, you would do some math in hal
to assert a fault if the heads get too close to one another.

I would expect that specific support for a dual head gantry machine would have to be done
by direct editing of the hal/ini files, not something that a generic GUI setup can reasonably do.
