I think I found the answer. it resets current head position each time after power as the new "home" position. So my conclusion is: it i put the head more or less in the rear left corner, and my print object is not full size (200x200mm) it should not give any problems. Is that assumption right?

However, pressing "Y Home" let the bed always clash badly at the far Y end, only exception is, if I move it beforehand to the left until it touches the microswitch. Though, even then, when moving 200 mm in one pass, it happens most times, that the bed clashes the other end for half a second, maybe half millimeter too short way.
Do I need to fix this and if, how?

then you have the Y microswitch not connected, or connected to the wrong terminals on the Duet, or the loom connected to the wrong tags on the microswitch. You should be using the two outer connections on the microswitch, not the centre one.

Thank you both, I will check that.
I have a new, more serious issue now.
The Y end stop at the motor side seems to be ignored by the board, this is new. This morning it was fine. If I click 2 or 3 times Y+100 for moving the bed towards the Y axis motor, then it does not stop at the micro switch anymore. The motor makes lot noise when it clashes with the micro switch and aims to move on.

It should be lit if the microswitch is connected correctly but not pressed. If the microswitch is disconnected, or if it is connected but you press the button on it (and you should hear it click), then the LED should go out.

Try moving the Y axis by had into the endstop. does the LED on the duet board goes out when you hear the click from the microswitch?

are you sure you connected to the correct terminals on the duet?

If that does work try the Command M119 while having the Y axis at the endstop. You should get the current sate of your endstops as seen from the firmware.

OK, here is another test to do:
Power off the Ormerod
Move the head to about the centre of the x axis, and the bed to about the centre of the Y axis
Turn the Z threaded rod until the head is at least 10mm above the bed
Power the Ormerod on
Check that the z probe reading is less the the threshold you have set in the G31 command in config.g
Check that the Y endstop LED is lit
Send this command:
G1 Y200 S1
The S1 is very important, it is what tells the firmware to check the endstop during the move. The bed should move towards the Y motor and stop when the microswitch is reached, at which point the red LED should go out. If it doesn't stop, check whether the LED is lit or not.
