Probably wiring issue, most probably missing 0V/gnd.
Pictures of wiring ? Upload here on the forum.

Try
HOME = 0
HOME-OFFSET = 10
odder
HOME-OFFSET = -10

Ok Thanks.

But I could take a Pi5 version of the pieeprom.bin from the github link and place it instead of the current one?

Both values can be set separately, so not a contradiction, if it is set to other values, it will be rounded to fit, usually there is no need to change it.

Did anyone notice the RPI4/8gb is more expensive than RPI5/8gb ?
Still, at 90E it is to much.
BTW, sometimes, i get nice deals on that website, being a good customer n stuff, they are the only ones that actually work here, they deliver to my door and they never failed to deliver whatever i ordered there, even when the price listed was wrong , example got 2 of Creality CR-5 PRO for 656 Euro total when the price was $1300 in china, for one!
So i can justify a bit higher prices for sure, but not for RPI.
End rant.
So what are the prices for ethernet variants?

yeah there's a bit missing from the image, that makes life easier.
I found the easiest route was install the RasPiOS image, change from wayland to X via raspiconfig.
Then install the RT kernel & Linuxcnc.

One of the RPi5 threads has the info to do this.

There's an update version here github.com/raspberrypi/rpi-eeprom/blob/master/rpi-eeprom-config

May i ask, why did you flash the Mesa card and where did you get the idea that you need to flash it?
I aks because i see more and more new members stating they flashed the cards, while in most cases there is no need for it, unless there is a need to change some card function.

In general, laptops are not good for running machines due to power saving options and latency issues that causes, but for testing some can be used, some can not, it all narrows down to how bad the latency is.
Attach the config files so we can have a look, in the meantime make sure the servo period in the ini file is set to 1000000 (1 million) and set it to 2 million and see if you get the error finishing read.
Mind you, changing that value requires changing other PID values, but we will deal with that later, after you get to at least have some time to test before the error shows.

I've installed the rpi-5-debian-bookworm-6.1.61-rt15-arm64-ext4-2023-11-17-1520.img to the drive, and can see it under lsblk.
PI is booted from the same OS on SD card.
To change the boot order, I believe I need to edit the BOOT_ORDER=0xf416 entry
sudo rpi-eeprom-config  --edit  however fails with:-
ERROR: --edit/--apply must run on Raspberry Pi4
sudo rpi-eeprom-update -a   
Message is :- This tool only works on Raspberry Pi4
Is there another way to change the boot order?


 

Thank you guys, I will take a look into those forum codes and feed you back some ideas guys.

• Official online description: traj_period_nsec = 100000 - This is the Trajectory Planner task period in nanoseconds. This value will be rounded to an integer multiple of servo_period_nsec. Except for machines with unusual kinematics (e.g., hexapods) there is no reason to make this value larger than servo_period_nsec.
• So it's a contradiction? It says traj_period is an integer multiple of servo_period, and then it says traj_period shouldn't be larger than servo_period.
• Core Components (linuxcnc.org)

This is the current actual pricing here, see if you can spot a glaring issue:

The prices of that supplier are exaggerated.
This is the site of a distributor in Italy  (www.melopero.com/shop/raspberry-pi/raspberry-pi-5-8gb/)

 

Ok so I have a bit of time off work again, changed my IP to 10.10.10.10 and able to flash my mesa 7i95T with mesact. I was having alot of trouble figuring out how to fill in most of the tabs, and my head is still spinning as to what is going wrong now.

I successfully created a ini and HAL (i think) and when I load up the UI gmoccapy I get hm2/hm2 7i95.0: error finishing read! iter=3324 <--- that number at the end was alot larger before I read about IRQ affinity here ---> forum.linuxcnc.org/38-general-linuxcnc-q...irq-affinity?start=0
The UI AXIS would get an error I can't remember, but does not do it after IRQ affinity steps, but gmoccapy still does sometimes. Does this mean my latency is too high? Even when it is working without an error code, i cannot get any motors to move. I am doing this off an old gaming laptop.

What information should I supply to ask for help better? I only reach out when I start thinking I might not be able to solve this

dont worry tommy, you can use ethernet also

Tommy I can actually believe that, but those prices look really high for both models. The RPi5 "broke" a lot of what works with the RPi4, especially if you want to play with gpios.
