Post-M6 - restore X,Y ?

Category: Advanced Configuration

I don't think moving back to the original position after an M6 is standard practice, all post should have safe move inserted after a tool change, this is not something dealt with on the machine side IMO
If your post expects the tool change to happen and the machine to not have moved and does not give you a way to implement safety moves to re-approach the work-piece after a tool change, this is just bad design of the CAM/Post the fix should be there IMO

current CPU frequency: 2.10 GHz (asserted by call to kernel)

All is good, move on to testing on a machine.

Keyboard Jogging Problems!!!.

Category: General LinuxCNC Questions

This also occurs with Qtplasmac. I can replicate it if I use the keyboard to jog and click to another tab while jogging. It loses focus/control even if I release the keyboard jog arrow and I have to go back to the main tab and tap a jog button again to get it to stop jogging.


I never realized this. I can replicate.

I will definitely be working on a fix for this. "Stay tuned."

Hello,

is there any gentelman which has running Xenomai or Cobalt kernel for his iron?

I need some inspiration or talk what, how, prons and cons ... experiences !

thanks

Tool changers are often more difficult than the test of the machine, if only because there are more variations.
What do the two motors do? What manner of toolchanger is it?

I would leave the kinematic as is and simply set the unused joint position to zero.

An der Dokumentation der 'devel' Version wird zur Zeit in grösserem Umfang gearbeitet.

Wenn du 2.9.8 verwendest solltest du sowieso die 'stable' Version der Doku verwenden: (beachte then Unterschied im Link)

Introducing halflow, an interactive graphical hal editor

Category: Configuration Tools

Signal wire colors default to color codes representing the signal type, but can be edited. If the rat's nest is a confusing mess of same-colored wires, double-click or right click a wire to edit its color. All wires connected to the same output are synced and will change to your edit.

You can also change the wire (hal signal) name, but the current version of halflow gives you no capability to load your edits back into your linuxcnc hal config.

Also not sure about the frequency on cpu 1. The governor looks right but current freq = 400Mhz. This doesn't seem good if I understand it right. (again very new to this)

$ sudo cpupower -c all frequency-info
[sudo] password for cnc:

CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0

available cpufreq governors: performance powersave
current policy: frequency should be within 400 MHz and 2.10 GHz.
The governor "performance" may decide which speed to use
within this range.

Question about an Intel NUC core-i3

Category: Computers and Hardware

I'm very new to this so please pardon the questions.  I recently acquired an INTEL NUC core-i3 with 8GB of ram. This is intended to drive a MESA 7i76e board on a plasma table.  

tldr; I'm primarily curious to know if the latency results I'm getting are going to work (if that's possible to advise).

I've downloaded the latest iso and  went through performance tuning.  I *think* I've done all the things.  It's sometimes hard to follow all the different threads on tuning.

1) Turned off things in BIOS (hyper threading, power management etc.). This left me with two CPUs
2) Grub configured (including isolcpus)
3) CPU governor set to performance
4) IRQ coalescing disabled (intel NIC)
5) CPU core isolated for LinuxCNC (cpu 1) (I am not sure how to confirm this is actually working as intended)
6) Ethernet IRQ pinned to isolated CPU (cpu 1)

The latency histogram as a result looks like this (6 glxgears & running YT videos):
 

~60 us of max latency.   Is this worth continuing to try to use or should I be looking at a better computer?  Any advice appreciated.

I have not hooked it up to the machine yet to try it.  Hope to be attempting that in coming weeks.  Thought I'd post this to see if I need a different computer first.
