in principle, yes,
but you would have to build the hal component in such a way that the ethernet packets are sent and received in parallel,
otherwise it takes too long.

EDIT:
but since udp is used, this can lead to collisions.
maybe send with minimal delay and then wait for the responses

Hi Linuxcnc community, 
I have installed OS in raspberry 5 and Instead of using IO expander I want to use individual ESP32+W5500 for every motor and generate step pulses. If this is possible please help me with the steps in achiving it.
Refer the image below and get what I want to achieve

Thankyou

I working also on 2 other new boards:

1. 3Axis adapter-board with NEMA17 drivers for the iceBreaker Devboards 


2. own FPGA-Board with ice40uP5k and 6Axis as Raspberry-Hat (hope it works ):


both can be build, flashed and connect directly from the RaspberryPi via SPI

 

Hi, i was solving issue with raspberry pi 5 with guys at etherlab, and from my understanding 1ms or 1kHz ethercat cycle is limit for genetric driver. You can get faster cycles when using native drivers like e1000 or igb for intel based ethernet cards.

I was just posting that but then got distracted.
I feel that too many are ready to jump to the latest kernel without really testing.

Seems to be a kernel issue, to many PC's having the same issue, i though this was already fixed by using new kernels.

Forum member Kam visited with a new (old stock) 7i96, got the same packet loss problem.
Tried Windows laptop and Linux laptop, with different cables, all fail.

I note that my install shows as LC2.9.1, not LC2.9.2 as listed in download page.

Replaced LC2.9.2 (1) SD card with a new SD card fresh Imager burn of my old image of LC2.8.4, SUCCESS.
2950 packets for 0% lost.

Both the LC2.9.2(1) and LC2.8.4 were official downloads.

LC2.8.4 loads and opens AXIS.
But still grappling with the Custom Hal to get my E-Stop control working.

Basically back to where I was prior to trying to get WiFi operational.

Now, some more investigation of why my LC2.9.2(1) fails.

Stay well,
John.
