If you use Mesa CT to make your configuration files it provides a lot of information about the selected card.

Yeah for sure, i was gonna make a little setup guide as soon as i have it done correctly so i dont have to do all the research again in the future, might aswell post it all on here for everyone that has similar issues

The config the user posted was for a 6 axis machine. If that's what you need it should be good to go once you correct the couple of mistakes.

If I may ask, once you have the basic config working, could you attach the files to this thread. As I attempting to have a one stop thread with a heap of info.

Awesome, thanks, will take a look and see what i can fix, i dont think setting up a config for 6 axis will be a big problem once i actually get the gpio stuff working

Regarding GPIO drivers.

For the Rpi5 please use hal_gpio
For the RPi4 hal_pi_gpio or hal_gpio (this looks like the easier option to setup) , should be no need to mess with permissions

What is the servo thread rate?

How are the ping times?

This may be a starting point
forum.linuxcnc.org/9-installing-linuxcnc...i-5?start=350#320817

But continue reading, as the user did make a few mistakes in the hal file, but these were pointed out in the next post. May not be exactly want you want, being 6 aixs, but it's a starting point.

But yeah it's hal_gpio for the PI5

Got a strange one with a Pi5...   Network seems fine when I am just pinging my Mesa card (a 7i76e) but when I run Linux CNC, things kick on but then the network crashes and I get a bazillion (technical term) hm2/hm2_7i76e.0: error queuing read iter=xxxx) and everything turns back off.. 

Once it dies I can't even ping the Mesa card (10.10.10.10) until I unplug and plug back in the ethernet cord... Then its happy as a clam pinging.. but once I start up Linux CNC again same crash right as the UI inits.

You may want to start reading from here:
forum.linuxcnc.org/27-driver-boards/4223...read?start=20#207308

Unfortunately I don't have any ethernet hardware to test with (only SPI), I have a 7i92 but that's in the mill enclosure and is a PITA to access. From reports the 6.12 kernel on the most recent RPi images have better latency, but I can't say whether that would solve your issue.

Versa Probe with Qtdragon hang

Category: Basic Configuration

I'm on 2.9.3, to my knowledge, I have not seen any changes in the values on the probe screen when it fails. I "think" I have seen a command in the linux status window, indicating a retract command when it is halting. But will double check next time.
 
This is how it looks when it works at least

I do not know how you guys even got so far: i have a Raspberry Pi 5 Modell B, 4x 2,4 GHz, 4 GB DDR4 and created images of v. 2.9.4 to SD card & USB drive with 3 different burning software including balenaEtcher. When i boot the RPi5 the drives are not recognized (as bootable) at all. With an image of vanilla Ubuntu it works just fine.

 
According the the RPi docs there is no RPi5 Model B, hmm screwed up on this, should have read further down, it does identify as 5-model-b, which can be found out by the following code snippet.
cat /proc/device-tree/compatible | tr '\0' '\n'

First thing I would is check the integrity of the download.
linuxcnc.org/iso/rpi-5-debian-bookworm-6...7-0140.img.xz.sha256
I test all images prior to uploading on a RPi5 4GB bought around Nov\Dec 2023 with latest EEPROM and on a RPi400 with latest EEPROM.
What I would suggest is boot to Ubuntu, then with a USB drive that you have written the Linuxcnc image to attempt to mount it.[/quote]

I see, what do i need to do to get it configured for the RP1? Might be a very obvious answer but im a newbie and dont really yet know exactly what im doing.

Do i have to do anything other than redoing the hal file? This issue seems to be a bit deeper than just the hal file (or atleast thats what makes ĺ
sense to me)

How to get MPG input (hm2_7i96s.0.inm.00.enc0-count) to move axis

Category: HAL

its a bit involved, you can look here for the basic hal setup

linuxcnc.org/docs/html/examples/mpg.html

(that happens to use a software encoder counter but the basics are the same)

Note that there are jog enable,count and scale pins for both axis and joints
The joint pins are active before homing and the axis pins are active after homing.

You could also search the forum for "MPG" as there may be a MPG setup using similar
hardware as yours.
 

Well thanks for that.

I now have the MPG working for the X axis and it was super simple (the example above gave me what I needed, and I only needed 4 lines to get it working
File Attachment:


#MPG 
setp axis.x.jog-scale 0.001
setp axis.x.jog-enable true
net encoder-counts  <= hm2_7i96s.0.inm.00.enc1-count
net encoder-counts => axis.x.jog-counts
#MPG ENDS

I have switches to manually jog, so I will use those to move significant distances, and then use the MPG to home in on the desired position, should make for a user friendly experience.

I will likely upgrade to ball-screws to fix the backlash, however at least now when I change direction the backlash is automatically dealt with.

I 3D printed a belt cover and mounted the X-MPG where the old manual cross slide hand wheel was.

Thanks for all your help, a Mesa board and HAL make customization really easy.
