PREEMPT-RT is close to getting merged with the mainline Linux kernel

Category: General LinuxCNC Questions

Noticed this article over at Phoronix:

www.phoronix.com/news/TIP.GIT-sched-rt-PREEMPT-RT

That is potentially very good news for LinuxCNC users.

I redid it again and it worked! It communicated... thank you very much for your help!

I concluded that I needed to install that package first... and then follow the step by step...

Now I'm going to look for how to configure this in Linux CNC since the communication exists now... is there a specific link for me to configure it? I believe I should be at the part where I configure the Linux CNC software now, right?

Yes it is.
The issue seems to be you have a new Linux/GLSL driver with an older version of VTK.

In your ini file, the P value for each axis/joint is set at 0, how did that happen?
The value should be 1000 for stepper systems with the servo period set at 1000000

Hey first of all thank you all for your awesome work!!
I have the same setup (I think) (www.aliexpress.com/item/1005006913304675...n.112.45bb1802PVhuo5)
And yes I can also hear the whining sound while the drives are active.
@Sandro would you be willing to share your whole config? I'm still very new to the whole config thing and the more files I have to compare to each other the faster I can learn.

Adding a progress bar

Category: Qtvcp

You can set it up similar to Qtdragon by adapting this code:
    STATUS.connect('progress', lambda w,p,t: self.updateProgress(p,t))

    def updateProgress(self, p,text):
        if p <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            self.w.progressBar.setValue(p)
            self.w.progressBar.setFormat('{}: {}%'.format(text, p))

    def percent_loaded_changed(self, fraction):
        if fraction <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            self.w.progressBar.setValue(fraction)
            txt = _translate("HandlerClass","LOADING")
            self.w.progressBar.setFormat('{}: {}%'.format(txt, fraction))

    def percent_done_changed(self, fraction):
        self.w.progressBar.setValue(fraction)
        if fraction <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            txt = _translate("HandlerClass","COMPLETE")
            self.w.progressBar.setFormat('{}: {}%'.format(txt, fraction))

In Designer, you must set signals from gcode_viewer and gcodegraphics to call percent_donw_changed and percent_loaded_changed.

Configuration for Lathe Tool on 7i95t boards

Category: AXIS

Hi
I was wondering if anyone can help configure 7i95t configs for VFD on my lathe machine (Current configs attached). The axis work fine but the machine is giving horrible threads as spindle RPMs and Z axis are not in sync. (Maybe due to some kind of software filter perhaps).
Also the encoder is a 1000 line ppr encoder. Therefore, the 4000 in encoder scale. 
If possible, kindly share the 7i95t configs with scale, filters etc. commands so that the bounce factor in RPM feedback for the spindle are removed. 

Have checked all the cables and they are fine!

RPi4 Mesa install: No 7C81 board found

Category: Installing LinuxCNC

I have connected pi 4(powered by PI OS) with Mesa7c81 using idc26 cable and followed the instructions given in the following video

BUT when i write the command sudo mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --fix-boot-block --wirte 7c81_5abobx3d.bit
I get the following error Unable to set bpw32 , falllback to bpw8
Unexpected cookie at 0100..0110:
00000000 00000000 00000000
No 7c81 board found
NOTE: i have already checked that spi communication is working using the ls /dev/spidev* command
Do you know how to correct this error? Your valuable suggestion will be highly appreciated.

I have a RPI 5 that will not install from the LinuxCNC 2.9.2 Raspberry Pi 5 OS based on Debian Bookworm i mage.
The RPI 5 is only the 2GB version. Would this be the problem?
THis RPI 5 works ok from the nomal Raspberry PI imager program

hi,
My machine has issue about following error keep rising during Gcode execution. Jogging 3 axis simultaneously at high speed ( 9m/min) for extensive time is ok. Reducing  the speed and accel to 3m/min  and lengthening timing pulse still doesn't fix the issue.
below are my hal and ini
