Just reinstalled the OS (LMDE 6) and while my regular linuxcnc rip install works I still have to copy copying 'liblinuxcnchal.so.0' to 'root/lib' to get it to start from your repo.

A bit of a newbie question I'm afraid.I've just done a fresh install of the latest version and hoped to get the Gnome desktop, but have managed to end up with xcfe.I have searched for and tried all sorts of ways, each attempt has failed. Example screenshot attached.Maybe I have to install again?Some help would be much appreciated.

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
