Fixed setting up a new install on a desktop pc, the same configuration shows the ATC tab as it should.. now I need to figure out how to configure the ATC according to my setup :

1) I have a servo motor with 17 bit abs encoder with an unknown gear reduction due to this retrofitted ATC. Setup with an INPUT SCALE: 157.48 it takes from 0 to 255 units to make a full turn

2) How to implement it in Probe basic is there a documentation?

thanks for your time

Somehow now that I decided to ask fot it I guess I finally succesfully installed it. using the autoinstall option, during the installation it asks if you want to force UEFI, at that point if you answer NO the auto-partitioner create just two partitions instead of three.

Then it finally asks you where you want to install the GRUB bootloader. where /dev/sda is the location to set

But if you just want to compare two numbers to see if they differ by less than a certain amount:

O100 IF [ ABS[#100 - #101] LT 0.01]
  <do stuff>
O100 ENDIF

Thank you.
I saw that documents, but  I'm not realized it can be done so simple way...

Apologies, the X, Y datum shift was me confusing the Home position and the Touch-off X0 Y0 for the job.

But coordinate rotations are a mystery.
I set G54 thru G59.2 sequentially to increments of 45 degrees with G10 L2 codes prior to the sub-routine, then the main.
The G59.2 setting was 315 degrees.

When the code ran, it cut at 315 degrees, even with a specific G54 (set to 0 degrees).

Problem disappeared when I relocated the G10 L2 P1 R0 code to the bottom of the list.
It appears the last rotational setting persists, even in the presence of a specific G54.

But, I still believe it must be me.
I am now going to re-read everything to do with G10 L2 rotations.
There must be something I am missing.

Edit:
Of course it was me !
Code errors that you become blind to.

All now good.

Hi, I want to report my issues with this installation specific to the hardware in the title.. I'm learning on the go, not a computer guy so I can say some bull***.
Assuming this pc is legacy only I successfully installed LCNC (title) on reboot I'm getting error no operative system found. So I made my research and seems in my situation I need to install GRUB directly on the main partition ./root ? I somehow successfully installed it via the installer, but cannot replicate what I did previously for a new install, luckly I was taking some pictures of the previous screens that I guess installed GRUB manually. 

In the source i see you how you handle expressions.

I shoukd use a lib like: mu parser to handle expressions. 
This also handles and updates gcode variables for you. 

It wont run (nested) while loops. This while loop algo you can design yourself.

in future i love to see gcode dialect parsing,
given a json config file.

Then hopely the interpreter is also able to read fanuc and kuka robot language and produce the motion outputs for it. An extended version off straight_feed xyz...
would look like straigt_feed j1 j2 ....

Mu parser example

Pcw had no luck on Mesa. The install script
destroyed his home directory back then.
This was done by a rm -rf command 
wich can do nasty things so we dont use that any more for cleaning up environment.

I only tested it on Ethercat with el2124 driven steppers and delta servo. 


 

Parameters still seem to be a problem to me.

Doing a polar pattern based on the test file posted earlier.
8 coordinate systems at 45 degree steps.

Shutdown overnight, now polar pattern off by 45 degrees rotation, and X,Y datum shifted.
The problem is most likely something silly by me, but the questions are still valid.

I used G10 L2 P1 X0 Y0 Z0 R0 to ensure G54 was where I started the polar pattern.
I this unnecessary and may complicate things ?

Should coordinate offsets be cleared before shutting down ?
How can I avoid parameters biting me in the future?
Should something be included in the shutdown.hal ?

John.

Möchte mich kurz für diesen Thread bedanken, hat mir bei der Einrichtung meines FU geholfen, nachdem ich mit Modbus kein Glück hatte (vermutlich Interferenzen).

In meinem Fall musste ich für das analoge Signal GND verwenden und für FWD/REV den XGND. Dann lief die Spindel

Any updates on Jetson nano projects?

I would love to use on mine horizontal boring mill. Does it supports Mesa based setup ?

Just keep in mind that all your traffic goes through them, so they know what your watching...

No that's disabled. They just do the DNS

You can monetise YT if you have 1000 followers and 4000 hours/365 days so I am on a mission to get to 4000 watch hours.

I think it is 3000 watch hours and 500 subscribers? 

 

Andy, that level lets you do some things but you need 4000 watch hours to get monetized for watch page ads. Scroll further down and you'll see.

And yes, YouTube runs ads in your vids regardless of your channel size...

My N100 system has rt8168 ethernet ports, and by default Debian installs the open source r8169 driver. It is better to install the official Realtek driver (r8168 in my case); more stable and lower network latency.

To rodw: can you show us a Latency Histogram screenshot of your tuned system? 

Just use your N100, follow my tweaks to get the best out of it

At this stage, I have only installed Trixie on my desktop. Yes, its a 20 core i7 but such hardware is totally wasted running linuxcnc. It's not relevant.

At this stage I don't think building the kernel will help much with Trixie because its running 6.12, which is the first kernel PREEMPT_RT entered the main line kernel code. In fact, its only one version behind the pointy end. Other than that, nothing much has changed from Bookworm.

I modified the homing.c to get it.
