I think motors are not tuned right?

From the screen shot I it doesn't look like the motors are tuned at all.
But, it is possible that the values in the INI file are not actually being used in the HAL file. Itis entirely possible to put the PID values in the HAL file and not reference the INI file.

i tryed this is the only way it works

The forum doesn't accept .rar files. It does accept HAL and INI files.

I have aded the files to your original post.

It does seem surprising that your machine is working at all, looking at the PID tuning.

Also, the reason that the machine is not as fast as it should be is partly that the PID tuning isn't complete, and partly that the machine limits are set rather low.

If you read this document: www.linuxcnc.org/docs/html/config/ini_config.html it explains what the various parts of the INI file do.
You probably need to change the MAX_VELOCITY in the [TRAJ] section to 300 for X and Y and 250 for Z. You also need to change the values in [DISPLAY] to allow the sliders in Axis to go that high.
Also, it is no good changing [TRAJ] if you don't also change the [AXIS_*] sections too.

I don't know what the peak accelerations are meant to be on your machine, but typically they are about 10x the velocity numbers. But start a bit lower and experiment.

Remove the references to STEPGEN** in the [AXIS] sections. You don't have any stepgens.

Very importantly, change the F-Error numbers. At the moment your machine allows the system to be 1000mm out of position. 1mm is normally too much.
You have
Change that to
While you are PID tuning, and then to

When you are running the machine.

After you have made the INI file changes you can start to tune the PID for the motors.

There is some useful information here:
gnipsel.com/linuxcnc/tuning/index.html

If you are using the Axis GUI then there is a "Calibration" item in the "Machine" menu that allows you to easily change the PIF FF0 FF1 FF2 numbers etc without having to re-start the machine.

Can i take the belts from the motors out ? Or if i start ajusting whit the settings right i might accelerate tu much and runnaway ?

If you take the belts off then the motor will have the wrong load (no load) and the tuning you do will be very wrong too.

Now that the following-error is set to a sensible value there is no danger of runaway, once it gets more than FERROR from the set-point the machine will stop.
