Laser and CNC Mill Offset

CharlesMakeAll

Is there a Laser and CNC Mill Offset in Repetier Firmware such as used with the extruders?

Repetier

No, but speaking of this i never programmed a change of offsets either, so it is using the last set offset from extruder.

Thank you for your answer.

If I may clarify, this means that if I use only one extruder, extruder 0, then both the CNC mill and Laser will use the position of extruder 0.

If I then add a second extruder, extruder 1 with an offset, that the CNC mill and the Laser will now use this offset instead.

Repetier

Not exactly, only if you had T1 before it will use Extruder 1 offset, otherwise it will stick to extruder 0 offset.

Thank you again for your help.

Please let me understand If I have this right.

I am building a CNC Mill - 3 Extruder - Laser combination machine using the Rumba board.

The machine is set up like this: 
CNC mill, Extruder 0, Extruder 1, Extruder 2, Laser.

So
according to what you have stated, since all three extruders are
defined in firmware, both the CNC Mill and the Laser will take on the
offset of Extruder 2, the last extruder.

As I understand this, I will be required to
set an offset in the Cad software (pycam) from Extruder 2 so the CNC Mill
and the Laser will position correctly under Extruder 0.

Repetier

NO! They take the offset from the last selected extruder. So if it was T0 it takes offset of extruder 0, if it was T1 it will use that offset. So if ext 0 is 0,0 you will have no offset after T0.
