You might try M84. This is either "G01 possible with spindle stopped" or "4th axis mirror image." depending on which manual you look at.

If it's mirror image, M80 cancels all mirror image.

This causes to start machining before the spindle has reached it's programmed speed.

3708#0
the spindle speed arrival signal (SAR) is:
0 not cheked
1 cheked

3715#0
This parameter specifies an axis for which confirmation of the spindle
speed reached signal (SAR) is unnecessary when a move command is
executed for the axis. When a move command is issued only for an axis
for which 1 is set in this parameter, the spindle speed reached signal
(SAR) is not checked.
0 Confirmation of SAR is necessary.
1 Confirmation of SAR is unnecessary.

Very much so !
Thanks for reconfirming this viorel !
...but still no feed after the changes to those parameters.

The M84 works great !!!
Thank you dcouper !
M85 or 'Reset' cancels M84

Now if i would want to remove the necessety to enter M84 for a program that requires feed with spindle. Lets say, (without having researched that corner yet) the M84 triggers a relay to close a loop that allows G1 with M5 and i simply bridge the corresponding contacts, practically activating M84 when power to machine is turned on.
The relay i chose as example, it could also be a parameter.
... anybody has experiance in what could cause problems with 'normal' machining operations?

I have 4 machines on divers fanucs that run the same program without problem but not that Daewoo. Because she is the oldest and slackiest of the bunch the managment gave me freedom to do what i (and you!) see fit.
With the parameters savely backed up of course
