What tommylight said indeed. HDMI CEC control off, HDD led off.
And these kernel parameters worked good for me:
isolcpus=3 intel_pstate=disable processor.max_cstate=0 idle=poll cpufreq.default_governor=performance i915.enable_dc=0 ahci.mobile_lpm_policy=1 irqaffinity=0 nomodeset quiet

Bad memory can also be a cause. You can check the following command to see if there are interrupts of other devices on the isolated cpus: cat /proc/interrupts
Did you check the temperature?

Good morning,

thank you very much for your time. You are right, Knuth is a german machine but the build this machine in china, like many other.
Look waht i found last day:
 
I want to find oz what kind of encoder is build in the machine... it is also from china.

I am with you. I also think the wiring is okay and i want to safe as much as i can.
Only for the safty i think this is not a good solution. Here is what i found:
 
There is a relay called KA0 (CNC ON/OFF) with two bottons on the panel. This cut off the power form the windows XP computer.
On this computer is the whole cnc with a pci card.
So you can cut off the running pc and cnc-controller with this buttons.
The machine also have two safty switches... the goes to the relay KC0.. but the relais goes to an input off the cnc-controller.
It is not hard wired to something else.

 
I have also a main- relay that cut off the power form the servos. But this relay is switched by the cnc-controller... not hard.

In my opinion i think i would connect the main power for the servos to the safty switches... if there is something wrong, than i will shut it down.
NC ON/OFF i think it is okay to disconnect the eneble... but shut down the hole cnc? Is this okay.

What do you think is here a good behavior?

I hase one other question.
I will use the tpuchdisplay of this machine to, but this is vertically aligned.
I am right i have to chnage the GUI for that?

I also want to use a handcontrol from china.  Link
Can i also use the wired one with linuxCNC?

Have a nice day
Martin

I found a rx 560 localy, I will see if it works.

Still doesn't work without copying 'liblinuxcnchal.so.0' to 'root/lib':

Should be able to add a digital input check to your tool change routine that runs a sub routine that measures your tool then forks back to your regular program. You could use a physical switch or an interface button, then use o100 if to check that input and run your tool measure routine. Exact impametation would be intersting. Perhaps an easier way would be to breakout your drilling gcode in to separate file and run them manually then continue with all your preset tools

Yes the kinematic model has to be written in C (or as .comp and then converted using halcompile )

ok some info for anyone instrested

turns out the gs20 has a gs2 compatibility mode that turns it in to a gs2 drive

Hi all, I am following this method to install linuxcnc and ethercat from source and then I am not very clear about the process behind it, is there any way I can download and configure the connection using cia-402 or can I just configure the hal file to connect.
I hope to get help from all of you.
Sincerely appreciate it.

Ethercat build from source - full instructions - LinuxCNC

Hi everyone, does the kinematics have to be written in C language? Can I write my own kinematics in C++ or Python?

Work ok

No, it's not.  I'm not bashing the machine, just the fact that they're obscuring the fact that the software is LCNC.

However, two things are crippling the lathe:

Clearpath servo for the spindle with no separate encoder - there's no index output signal.  Which means you have to 'home' the C-axis and do all milling/indexing operations in one go because you can't re-home to the same position after taking it out of C-axis mode.

And the 1/2" diameter limitation is a killer.

That lathe, with a spindle encoder (or servo with index output) and 1" spindle would be pretty sweet.

And if they could beg/borrow/steal the pneumatic collet closer from the Sherline, they could have a REAL swiss that takes stock longer than a foot.

One closer on the spindle, one on the guide bushing frame, and you could feed barstock of (mostly) unlimited length without an expensive bar-feeder.

Oh, and there's this...

 

First, test withIf that is still bad, see if you can set the package power limit in BIOS to 0 for both sustained and burst mode,
Then try disabling WLAN it can cause huge latency spikes on some of those NUC's

Yes and yes.

I assume the machine configs define things like:

- number of axes
- stepper motor count per axis
- axis limit switches
- spindle functionality: fwd/rev, variable speed, output signal (0v - 10v, etc),
- estop functionality

…and so forth. Maybe they also define your motion control board and any daughter boards too?
