LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

What you were trying to boot a RPi5 with a amd64 image ?

Of course I provided the RPi5 checksum, why wouldn't I, this is a thread for the RPi5. The checksum will only work when used against a file, not a mounted file system, the checksum is for the compressed image file.

Am I missing something here ?

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Thank you for your help, please notice my linux knowledge is limited so my answers may sound stupid :-). Anyways
cat /proc/device-tree/compatible | tr '\0' '\n'
returned:
raspberrypi, 5-model-b
brcm, bcm2712

The checksum did not match, but the link you provided is for rpi-5-debian-bookworm - I used the linuxcnc_2.9.4-amd64.hybrid.iso

Anyways, I mounted Linuxcnc image under Ubuntu and all the checksums there matched when i used
sha256sum -c sha256sum.txt

2.93 Axis (for now will explore other GUI's when I have everything sorted out)

This is a great strategy!
I think in the machine menu, there is a homing menu for each axis but I don't have a sim handy to check.

For those interested in Tilted Work Plane implementation on 5axis machines with work side rotation see:
forum.linuxcnc.org/show-your-stuff/55248...utating-table-rotary

Note that this covers also non-nutating kinematics (just set the nutation angle to 90°) and covers BC as well as AC table configurations (adjust 'table-angle' between 0..90°)

Here is an example from a recent config I did.
HOME_OFFSET = 8
HOME_SEARCH_VEL = 10
HOME_LATCH_VEL =  10
HOME_FINAL_VEL =  5
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 1

Back to your points, 3 & 4 happen very quickly as it only backs up far enough to clear the switch so it is probably working fine
If you are going the wrong way at the end, invert the sign of FINAL_VEL
HOME_OFFSET defines the final position, in this case 8mm from the switch to give a safe margin. Sometimes I will use 0.5mm or similar if travel is limited.

Played around the designer a bit and managed to make a vertical screenset based on this topic. Perhaps it will be useful for someone. And I got closer to the idea of having a universal version of the screenset that can fit all my machines, current and future.

None of the Linuxcnc images and ISOs install a root user so sudo is required
Sometimes I do: sudo su
which gives you a root access (you will see the prompt change) untill you type: exit

Hi Olli
Thank you once again for your prompt response to my issue.
I have done a very quick test and at the moment I am over the moon, all the outputs work as they should.
I am using your template for N4D3E16, with exactly your settings.
When I use LinuxCNC it works perfectly, but if I use the test-gui in riocore the outputs work, but i get the following errors in the terminal window.

I will test for a little while longer to see if I can figure out if I have configured something incorrectly.

To use the inputs originally I used the following settings. I cant remember why I broke them into lots of 4, I'm thinking that if I put a "values" as 16 it wouldn't work

"inputs1_4": {

},

Okay, left to my own devices, late at night with little to no research this is the best i could do. 

I realized that i believe i can see it back off in the correct direction then for some reason just starts going into the positive direction (which is wrong)

This homing process started from -0.5"

7i96s Replacement Needed

Category: General LinuxCNC Questions

Hi,

I was working on my CNC mill with EDM attachment tonight when a short seems to have taken out my 7i96s.  The machine was never really grounded properly and a drill was laid across from the hot side of the EDM to the rest of the machine.  When this happened everything turned off and now the board is kind of ticking on briefly then immediately back off.  About once a second. The steppes are kind of stepping once when this happens. 

I assume that I need a new board.  Of course mesa is out of the 7i96s right now.  Idk how long they will be out.  Does anyone have any suggestions? Is there another board that is a good alternative to the 7i96s? Is there a reseller of these boards? Does anyone have one they would like to sell or get rid of?
