So cool you took the time to make this video for us !

Interesting. The evolution of these systems is intriguing.

Thanks for sharing. A couple of questions I had while researching LinuxCNC and EtherCAT. How would a Beckhoff EL2521 be used to drive a standard Step/Dir Stepper driver? I see it is a supported Beckhoff terminal however I have found little mention on the forums of it's use. Perhaps a video if you have a EL2521 handy? I would also enjoy a follow up video going over the encoder input, I am currently looking into 0-10V and fwd/rev vfd control with encoder spindle feedback using Beckhoff EtherCAT terminals and LinuxCNC.

Hello, Thanks for your great video. I was waiting for that. I'm about to build a cnc machine using raspberry pi. My concern here is that I already bought servo stepper motors from stepperonline with a controler that doesn't have ethernet port. It's the cl57y. But It's got an alarm signal. Do you think I can still use the advance functions of linux cnc such as recovery position in case of emergency ? Can I still use the same setup as yours ? Probably not the same BOB. Thanks

thanks for the contribution, can you also connect sensors for reverencing the axes, or other inputs

How did you write sd card with linuxcnc-2.8.1, I have used rpi imager to write sd card but its not booting. Also I have tried other images but they don't have same kernal as shown in notes (linux-headers-4.19.71-rt24-v7l). Is there any alternate solution for this ?

There's a lot to digest here but maybe for my second or third generation of machines this will be the right approach.

Thank you for the video. This was very useful for me. I have a Beelink mini pc instead of a raspberry, but I'm using that to drive 3 nema34 stepper motors with the Rtelligent ect86 ethercat enabled stepper drives. I use usb to rs485 to control my spindle speed which is not so time critical.

Great video. Very helpful. Dang, I have been studying up using LinuxCNC with Mesa cards. Now another possibility to mull over.

Hey @MetalMusings, Thanks for your wonderful video. I saw it many times to understand how command lines worked. In my case, I want to use Raspberry Pi 4 B as an EtherCAT slave with Beckhoff IPC for an Injection Molding Machine. I followed the same steps but unfortunately it didn't work in my case. So, please assist me with how I can use Pi as an EtherCat slave and if there is any Kernel or add-on needed, please share it with me. Additionally, please let me know how to approach you for any specific query such as how to test latency in this EtherCAT communication and to read and store this real-time data of the molding machine on Pi (with the help of CodeSys whose runtime application is running on my Raspberry Pi 4 B) ?

Another super video, I learned so much I forgive the lack of broken endmills. It would be fantastic if you gave your thoughts on ethercat versus a mesa system - e.g. what advantages ethercat brings to the table and why you're exploring it. I haven't found anything online about "why ethercat" except sales pitches from manufacturers. (Of course "because I was curious and felt like it" is a perfectly good reason too.)

Hi, personally i think there are many benifits if you can get over the setup software hurdles! - No step/direction wiring - less prone to interference/ noise - Absolute encoder interface, no homing required, just a once off zeroing procedure. - you can map your drive io back to linuix cnc totaly removing the need for an io module.(depends on drives) - You dont need a BOB like any of the mesa setups. I think when you factor the build time and materials, cost are lower than other options too.

hi, firstly thanks for this amazing work. I have a question. This system (raspberry pi 4 + ethercat + linuxcnc) can use for time critical operations? Because I assume that OS is Linux_Preempt_rt so this is a real time system, and you use ethercat it is the most powerful comm. protocol. So if we design our own user interface can we use this system for time critical operations? Thank you.

Hey ! great video my friend ! I just would like to ask what Hz (steps/minute) can we get with rasberry pi using ethercad? Because using rasberry I/O gets only couple of kHz
