I get it the rest of us are on double secret probation.

i guess in my case what i have drown that it will be mix of twos, since x axis(table) will move with + to the left (as usual cnc does) and others two as you said. Wondering can it cause any problems with configuration or smt else

I came back to this topic again, and I had a new idea. I want to make a semaphore thingy using RGB LEDs. I used 3 OUT FLOAT, which I connected to PWM LEDs. The hardware works fine, the colors change, but I'm stuck on how to write the function correctly. Here's what I came up with:
It seems to work, but only once at startup. How can I make this function run continuously?

We figured out the setting of the parameters, thank you. The program starts normally. Home search is normal.
But running any g-code program fails. Moreover, an attempt to move manually (with arrows on the keyboard) leads to the fact that only each motor moves separately - i.e. not two X X motors, but one X motor, which immediately leads to an accident.

#2025-11-20 для 2.9.4
#KINEMATICS = trivkins coordinates=XXYYZ
KINEMATICS=matrixkins

Where exactly and how exactly can we now indicate that we have 5 engines and an XXYYZ circuit?

ini-file:
[KINS]
    JOINTS = 5
   
    #2025-11-20 для 2.9.4
    #KINEMATICS = trivkins coordinates=XXYYZ
    KINEMATICS=matrixkins
   


[HAL]
    HALFILE = 4.hal
    HALCMD = setp matrixkinx.C_xy 0 # Skew Y axis towards X axis
    POSTGUI_HALFILE = postgui_call_list.hal
    
[TRAJ]
    COORDINATES =  XXYYZ
    LINEAR_UNITS = mm
    ANGULAR_UNITS = degree
    DEFAULT_LINEAR_VELOCITY = 25.00
    MAX_LINEAR_VELOCITY = 250.00


 

But another problem immediately appeared!

when you try to run a regular program, errors will appear
about the release of a program for A and B positive limits!
I don’t have A and B axles, but for 0-4 engines all the limits are set correctly
XXYYZ!

But how to correctly write the value of one of the parameters in the settings? If earlier I could provide in a hal file
setp relkins.adjX.Y0 0

now it's an attempt to indicate

setp matrixkinx.C_xy 0

leads to abortion program launch

Through HalShow, the command setp matrixkinx.C_xy 0 is executed normally.

Bravo, thank you!
The interface immediately changed - before home, a choice of individual motors is now available!
There was an error in the perception of the hal file configuration when I tried to write down the parameters
setp matrixkins.C_xy 0

Thank you, of course, I'm a hat and stupidly downloaded the html page. We have advanced

unknown,

Do you have a Debian Trixie version with RT-PREEMPT kernel for a RaspberryPi 3B+?
It is everywhere written that Trixie already is ' real-time', but I faced a lot of issues when trying to run LinuxCNC on Trixie. Especially on a RaspberryPi 3B+.
