I have tried to read but not so clear for a bloody foreigner

If the scale is correct, are your maximum velocities reasonable?
Have you read the LInuxCNC ini file documentation?

The last ini file of yours I looked up had values much higher for max vel (250 for max_velocity, and 350 for stepgen_max_vel on the slowest axis and others were even higher)
You would need either slower max velocities or shorter step timings, or a combination of both.

To meet your ini file's stepgen max velocity value you had for X of 350 (800 for Y-Z), the sum of the step length and step space values would have to be less than about 700ns (300ns).

Guys, first of all I have been way out with my numbers (mixed up with previous router I had) so my apologies.
1. Drivers where not set correctly = now they are in quad and work OK, well a bit too fast.
Still having the error message so I will be tweaking my numbers.
Original speeds with the Siemens system and DC servos was
Fast transport X/Y 5000mm/min = 83mm/s and 2500mm/min = 41mm/s for Z
Will report when have error cleared out.

So now no error messages.
Q:
Where do I set max velocity = keyboard jogging + shift key >>>>>>> WAY TOO FAST

Jogging velocities are generated by the GUI, so:
[DISPLAY]DEFAULT_LINEAR_VELOCITY
linuxcnc.org/docs/2.7/html/config/ini-co...tml#_display_section
But, you are holding the shift-key, and I think that means "jog at full rapid rate"

I _think_ that DEFAULT_LINEAR_VELOCITY is what you get with an unshifted arrow and the jog-speed slider at 100%
(And, yes, I think that shifted-arrow will use the 85mm/sec.)
It should be a fairly easy test to check it against the DRO numbers.

As I get no positive results testing above i wonder how this must be done.
Have 2 swithes I need to get working on my front panel.
1. Coolant Flood
2. Oiler pump
1 already has net to output, but I need to do this manually also = How to do this.
2. input on 7i73 > output on 7i76e but I also need to have this to be run via G-code (just for test = coolant-mist)
Is above to be done with some OR ?

Question
I have a manual switch on my frontpanel and want to be able to run flood coolant manually.
Following in my hal file
# ---coolant signals---
net coolant-mist <= iocontrol.0.coolant-mist
net coolant-flood <= iocontrol.0.coolant-flood
# --- DIN-01 Coolant pump ---
net din-01 <= hm2_7i76e.0.7i73.0.1.input-20
# --- COOLANT-FLOOD ---
net coolant-flood hm2_7i76e.0.7i76.0.0.output-04
net din-01 hm2_7i76e.0.7i76.0.0.output-04
Is this the correct way to net functions wanted?

Thats becasue nothing is connected anywhere. I think you need
so now the input is connected to the iocontrol signal. YOu had just created signals before and done nothing with them.
Never used coolant so I am not sure if this is perfect. I'm not sure if iocontrol.0.coolant-mist is an input for a switch or an output for a LED indicator.
# ---coolant signals---
net coolant-mist <= hm2_7i76e.0.7i73.0.1.input-20
