I had a badly worn (1938) manual Bridgeport that I converted to CNC by adding a ballscrew assembly. Everything had some amount of spring to it, but there was a lot of wear in the ways that made it possible for the table to rock in several different ways. I finally found a much newer R2E3 Bridgeport (BOSS8) machine that was built for CNC from the ground up. Also, the ways are in vastly better condition. Well, there is SURE a difference in accuracy of machining! The old machine was tolerable, the new one is excellent! I also made a MUCH more compact CNC retrofit in the existing servo cabinet on the right side, and completely removed the electrical cabinet on the back of the base.

I installed 6.1.75-rt23 on SD card and it works ok on Orange-Pi-5. I tried to put it on nvme and it didn't work. It freezes when booting. Please can you put a version that also works on nvme.  

Das funktioniert bei mir nicht ich kann die C-Achse nicht mit der Tastatur bewegen

Gracias por tu respuesta, pero llámame estúpido, pero no puedo descargar la última versión. La versión que se ha descargado es la 1.235.265.
He actualizado Debian 12 a bookworm y el kernel es 6.1.0.26-rt-amd64

The thing costs more than 4 k€. (probably more advanced than the Makerspace kickstarter for less than 10% of that)
I wonder what a 3rd hand machine would cost.

Maybe this link is useful.

 When I open the Linux cnc it start like that: 
 

When up jog up:
 
Same thing with homing : It go up fast click returns slow click and goes above the switch. 

Is there any other link except this   linuxcnc.org/docs/html/config/ini-homing.html   one where I can read about the homing routine. And other then this linuxcnc.org/docs/html/user/user-concept...chine-configurations for machine configuration. 

 

 

as a side question, what are you changing? can you share some pictures as it may be one of the things getting updated currently that will be available on the develop branch.

build a deb file to be installed. if installing from deb you would want to follow the instructions for that from the probe basic website once built. just substitue your probe basic deb file for the one listed in the installation instructions. qtpyvcp and hiyapaco would be installed from the guide as normal since you are only changing PB.

i have not tested this myself, but this is how one of the other users/devs builds his customized probe basic deb files.  this would be built by running in temrinal inside the dev/probe basic directory.

From 2.7 to 2.9.2, using Axis GUI.
I always use USA standard keyboard keymap, i never ever change that, i had to learn every key on the keyboard as using several PC's and laptops daily with changed keymap was a horror !
Edit:
Just tested on 2.10, also works moving A axis.

follow the wguide on the probe basic website, it is easier to keep updated and edit (as you have discovered trying to edit your post above..lol)

post the errors you are receiving, they help direct us to where the issue is. im not familiar with the config builder you used or how it formatted the hal file so its a bit difficult to do a quick compare. i alsways use pncconfig myself because of old habbit. but so long as everything is there as it should be i don't think that matters. post the error log in full, that will have the offending bits and pieces for the current issue. it may take a few times if there are more than one but eventually once they all get sorted it will load same as the sim does.

Preempt-dynamic is not preempt-rt though:
stackoverflow.com/questions/77564174/is-...-dynamic-set-on-full

Some things to consider:
-Z axis should have max_limit set to 0 or thereabouts
-Z axis should have min_limit set to -400 in your case
After fixing that, check that
-Z axis move in positive direction going up by looking at the DRO on screen?
-Z axis move in negative direction going down by looking at the DRO on screen?
Only after getting this correct, move to check homing.

Wenn du die Version mit dem Update möchtest, dann ja.

@tommylight, what version of lcnc does this work on for you? Does not seem to work for me in '9axis'-sim in either 2.9 nor master.
