Changing extuder output axis

Just converterd my cnc to a 3d printer and have the extruder setup on axis B how do i change the gcode output in slic3r so the extruder output is axis B thanks for any help.

This is a guess, but it sounds like that is a firmware thing.

The g-code is "standard." My understanding is the code says extrude, and the firmware that is specific to your machine will take all the extrude codes and sent them to your specific axis, or motor.

Hope that helps; or at least points you in a better direction.

Regards

I am using mach 3 to drive my cnc machine which is three axis with the x axis using two stepper motors driving it X and A.
So I have had to setup the extruder to axis B.

When I read the outputed gcode from slic3r in notepad it is controlling axis x,y,and z and is using axis E for the extruder axis.
I was hoping that there was a way to change setting in slic3r so it outputs the extruder gcode as axis B and not E.

Hope this makes sence new to 3d printing.

An example of what I am talking about, is there a way to change the E output to B in Slic3r , I could see if I can change the axis in mach 3 to E then that would solve the problem but dont know if this is possible.

The only thing I can think of is to write a python post-processing script. I've never done it myself, but it sounds fairly easy.

Or you could fork Slic3r, and make the modification yourself into the source code. It is very easy after you find out where to make the modification. You could ask Sound about it in IRC.

Export Config.ini to a known destination.
Enter editor with config.ini
Find this line: extrusion_axis = E and change to B.
Import this config.ini to Slic3R again.

I changed my CNC/3Dprinter this way to be A.
