adapting a dremel to a duet

Guys i am thinking of trying a small router i have on my mendel rpp. The problem is that i dont know how to setup a gcode for that . from what i cant tell is that the gcode should be written upside down . Is there any easy way to do this ?

This sounds like more of a slicer problem then a printer board issue. Thinking about it you couldn't just reverse the g-code because you would still need to lift the drill bit up for moves.

Yes indeed it is a slicer problem. The title is way off. Sorry guys.
The bit up on every move reminds me the retraction and i wish it would be the only problem. Can the slic3r produse such a code? Or simplify3d ?

You don't do subtractive manufacturing with a slicer. That's for additive manufacturing with a 3d printer. Read about CAM software. It also produces a G-code file, but designed for cutting and removing material.
The best free tool out there at the moment is Autodesk Fusion 360.

and there is the duet ...! would it be able somehow to read-work such a code ?

Yes with some limitation. Duet does not support G2 and G3 (Controlled Arc Moves) which CAM software for CNC milling/routing use quite extensively.
There is a workaround for this, which is quite simple. Post-process the G-code file in "G-code ripper" which will convert the Arc Moves into small linear moves (G1).

Otherwise, I don't see any reason for this not to work, as long as you don't use other CNC specific commands like controlling coolant, spindle speed, tool change, etc.

Also the Christan's fork of RepRap Firmware (https://github.com/chrishamm/RepRapFirmware/) has a section instigated by me to control a Roland Modela CNC mill.

The Roland talks its own language as opposed to G Codes, so this takes G Codes and translates them into that language for transmission on a serial port from the Duet to the Roland at 9600 Baud (which is what it likes) using a piece of electronics something like this: [github.com].

But mechanically the Roland is just a three-axis CNC mill, so if you just take the translation and serial code out it may help form a basis of what you want.

(I use this for PCB milling on a pretty much daily basis.)
