LinuxCNC on Raspberry Pi 5

(Sorry for double posting. Cant edit last post, can only see the block quote when i try to edit)

I found a solution for my missing WiFi connections.
Second method mentioned in the top reply. (first method didn't work for me)
askubuntu.com/questions/71159/network-ma...s-device-not-managed

***
.....
Then open the file:
sudo nano /etc/network/interfaces
Delete everything in that file and copy and paste the following:

auto lo
iface lo inet loopback

Save, stop and start network manager:

sudo service network-manager restart
***
I had to reboot my whole system but after that WiFi works like expected.

So with the official image if I install Network Manager then it fails at between 50k and 70k pings... However if I leave the network bone stock like the image (so using commandline and config files to manage) then 100000 pings at 1ms/ping and a response time of 0.105ms so yah... I think it was Network Manager that was the problem.

What is the actual command are you using for ping

After using two model of pi (4B and 5) I still get disappointing results. Even at slow printing speeds around 25mm/s there is layer shifting and unreliable motion throughout the operation. I believe now that pi + GPIO struggles to keep up with the pulse generation. Even though I am doing indexed printing (orienting the bed only between sections of printing, so no full 5 axis kinematics) My application is a 5 axis (3 + 2 tilting bed) 3d printer.

I think this was mentioned in the instructions that the PREEMT linux kernel was compatible only, but not recommended as 'industry standard'. Since I cant afford a Mesa FPGA card I am going for klipper on an Octopus board and try my best there. Thanks everyone for being super helpful. And if anyone is interested my 5 axis slicer is on Github, it is A Blender addon that works if you also have the Cura engine up and running. You would be able to slice more complicated models with overhang and printing it by rotating the bed (if you do have this kind of setup).

""I think this was mentioned in the instructions that the PREEMT linux kernel was compatible only, but not recommended as 'industry standard'.""

What do you mean by this ?

I guess you haven't seen this:
github.com/ozzyrob/Linuxcnc-FPGA

I mean by that you need additional hardware to get good results. The Pi alone even the 5 cannot handle it is my finding and conclusion.
