I got it!

You just insert text vfeed:feed_value to specify vertical feed. Then select all, right-click and choose Properties. Set Pozition Z to desired drilling depth (must be negative).
Rename the layer depending on your drill diameter, as manual says. Select all and run REALIZE.

I attached the output for vfeed = 150 mm/min. I moved all dots closer to 0,0 position for your convenience. I see that you use mm dimensions, so do not forget to change G20 to G21 in the output file (I changed already in the file).

File Name: drill2.ngc
File Size:25 KB

upd: I tried to open the file un EMC2, it fails. Comment or delete the string

Ndrill Tdrill M6 G43; DRILL ?

and it will be fine

@PKM Thanks man! That was awsome! Your answer helped me a lot. Now i know how to use this Realize for AutoCAD.
I can import the files now in EMC2, but do you know what is about with the error from the screenshot bellow ? I tried it on your version of ngc and my version of ngc and i get the same error when i simulate ? Did i forgot to configure something in EMC2 ? I'm using 3Axis. I think i'm a tired.. and sorry for being a little wooden-headed

First and third errors - the tool tries to move out of your machine's workspace, thus joint limits exceeded. What is the actuator/table stroke of the machine? You probably need to rotate the workpiece (and dxf picture) 90 deg, usually X stroke is longer than Y.

If axis 0 is in the middle of table stroke, you might only need to move the workpiece and touch off.

The first on means your part is positioned so some of it falls outside the X limits of your machine.

Thank you, this was really helpfull.
PKM you should make a tutorial on how to use REALIZE because you can't find anything related to this software except the author's instructions which are a little vague on my opinion. I think this script is not so popular because it implies the use of AutoCAD which is very expensive for the average user.

Thank you once again for your help. +Karma

You're welcome.
It's Chris Radek who we should thank for writing and sharing the script.
