So interesting in the top notes the is the bit about only supporting amd64 for apt install but further down there are the instructions about how to install for pi 4 and 5. So i wonder which is correct.

ARM64 Raspberry Pi 4 and 5 Installation Repository:
sudo apt install curl
echo 'deb [arch=arm64] repository.qtpyvcp.com/apt stable main' | sudo tee /etc/apt/sources.list.d/kcjengr.list
curl -sS repository.qtpyvcp.com/repo/kcjengr.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/kcjengr.gpg
gpg --keyserver keys.openpgp.org --recv-key 2DEC041F290DF85A

Going by the docs you linked to the apt install is only for amd64.

Good morning.
for some reason it seemed like it would be fun to set up Ethercat and LinuxCNC and ProbeBasic so here we go.  Downloaded the 2.9.3 image from (forum.linuxcnc.org/9-installing-linuxcnc...or-raspberry-pi-4b-5), Then went to follow the standard instructions for installing probe basic from the install site Probe Basic Install.

Followed the instructions for the Arm64 (kcjengr.github.io/probe_basic/stable_quick_start_apt.html) but get the following error message on trying to do the Apt update before installing

N: Skipping acquire of configured file 'main/binary-arm64/Packages' as repository 'repository.qtpyvcp.com/apt stable InRelease' doesn't support architecture 'arm64'

I have checked the kcjengr.list file at /etc/apt/sources.list.d and it lists the arch type as arm64

Thanks, just ordered one with GoFundMe contributions.

here is my excuse:mitsubishi rv-e2 

 

without controller and one harmonic drive is broken
 

I approve of this excuse!

Quick question about the iceshield config:

Should the pi be emitting 18mHz, rather than 5mhz via pin 7 instead, since the oscillator is configured as 18mhz on pin 35 on the up5k? I wonder if this is the source of my following error at higher speeds?

Is it  possible you have lost the link? (maybe 7I96S 5V power issue)

What does:

sudo chrt 99 ping -i .001 -q -c 10000 10.10.10.10

report?

(will run 10 seconds and report ping statistics)

I get greeted with either of these two screens when i try to boot up my machinee. its a fresh install of linuxcnc 2.93 on a raspberry pi 4 cm4 and a 7i96s, i have tried with other realeses but the issue remains the same. if it loads in to the program thee error messages pops up after a few seconds so not instant. Does anyone maybe know why or could point me in a direction because now im completly lost

First of all, my deepest deepest sympathies,sorry to hear you live in Melbourne, the only good thing Victoria has to other is Philip Island and the roads, airports and docks that lead out of the state.

Why aren't you using the premade image for your RPi ?

The links are on the Linuxcnc home page under downloads.

@ccatlett1984 That was a bit of a pain to do, I would not recommend unless you have experience soldering and particularly desoldering.
I removed the factory Raspberry Pi two row header and soldered on a new stackable female header in it's place from the bottom. A
good tip to help with factory header removal is to pry off the plastic and desolder each pin one by one.

I want to say the exact part I used was a Pololu 2749, but check the dimensions of the header to be sure.
