Placehold variables for Custom Gcode

I want to move the extruder up and away a certain distance above the finished print.

Adding a fixed value custom End G-code command like G0 Z100 will not work if the printed object is 150mm tall
I see in slic3r 098 that you can use placeholder variables but I can't find any info about this

Example:
I need to add 100mm to where ever the extruder is currently at when the print finishes

So if the extruder finished at Z125, I want the Z axis to move to Z125 + 100 = Z225

Any help is appreciated
thanks
Doug

You have a couple of options.

G92 Z0.
G1 Z125.

The first line resets z axis to zero.
The second line is your move.

G91 G1 Z125.

G91 switches to incimental mode. Then your move.

G92 Z0
G1 Z125

This method will work
Thanks for the info

Be aware - G92 sets the Z axis origin to its current location, so a G1 Z125 will raise you 125 above that - not 125 above the bed.

I have postfix code to lift 10 millimeters and use the G91 approach.

Thanks for the tip

I'll experiment with G91
