This patch for LinuxCNC should be sufficient, it will still look for the PREEMPT_RT in uname but removes the check for /sys/kernel/realtime
 

With this environment setting you don't need any patch by the way
LINUXCNC_FORCE_REALTIME=1  latency-histogram

Hello Sir. Could you please provide some help on this post? I am kind of facing a similar issue but i dont know how to change the data transfer mode of my parallel port to support 9 input pins. forum.linuxcnc.org/38-general-linuxcnc-q...with-9-inputs#320147

 

NOT ALL PARALLEL PORTS SUPPORT MODE X, YOU HAVE BEEN ADVISED TO READ THE DATA SHEET PERTAINING TO THE CHIP. THIS IS THE THIRD TIME I HAVE ADVISED YOU TO DO THIS. I think you will find that the pins concerned are not open collector pins.

Hi,

Here is the first test result of the triangle centroid path smooth algo.
The algo is not finished yet, as this is only the first iteration. The second
iteration smooth's even more.

G64 P5 => it indeed filters out the 5mm spikes in the gcode.

Scurve + cenroid smooth

For me it works under a fresh installation from VisualStudioCode with the extension PlatformIO and GIT under Windows, too.

Ther are in the folder c:\Users\Your-User\ the folders .vscode and .platformio and C:\Users\Your-User\AppData\Roaming\Code . I think if you delete all it's like a fresh installation.

I just wonder did the M190 file change between version 2.9.2 and 2.9.4 ?

I made a new configuration based on the current one and saved it under a different name. On the new one there was no error message.

So in the current configuration I replaced the file called M190 with the new one now everything works.

I have a GUI written with QT5. Than I upgrade it to QT6 because I would use new kernel 6.10 rt-14. Egalax multitouch panel work not so great. Or better:

• If try to run a standalone GUI in QT6 all work perfect with egalax touch or with mouse
• if try to run linuxcnc with Axis Gui all work perfect with egalax touch or with mouse
• if try to run linuxcnc with Gui written in Qt6 with mouse work perfect, with touch it not grab every time press event but every time touch grab x-y on screen ... so can not perform push and release event everitime is needed with egalax ... but I can with mouse whitout issue.
  
  I'm not expert in x11 input and on linux mint 22 (but check with debian is the same) not uderstand where check for solve these issue ..... seems sometime make interferences with QT6 input event system when run Linuxcnc application only .... if run a test standalone GUI written in QT6 (mine test calculator app for example) and at same moment classic Axis gui with ethercat linuxcnc, linuxcnc work great with mouse and with egalax too .... same for my calculator app.
  
  But if run my QT6 GUI for linuxcnc & linuxcnc and at same moment my calculator app, calculator app work great with mouse and with touch, but GUI QT6 linuxcnc work great only with mouse.
  
  These make me very crazy .... not understand how to check for solve these strange issue .... what can make interferences of Linuxcnc into QT6 about evedev input system or other input library used from system? AN why only with touch screen??
  
  Really appreciate any help.

my question now is how to get it to work with qtplasmac, i cant get it to work even though i copied all the necessary config lines in both hal and ini files from my par port configs
can anyone help me with this
Thanks in advance

The documentation is outdated, try clicking on the colored channel buttons on the bottom of the screen to toggle channels on/off. Eg the red button with '1' on it.

Thank you.
