Cutting a scaled down prototype of my project design¶

I followed this Tutorial to learn How to arrange a multi part 3D model for milling. https://www.youtube.com/watch?app=desktop&v=jeQPJHHwVN4. First it didn’t work (For an apparent license issue That was solved with a restart an upgrade of my Fusion 360). I was also having difficulty finding to right post processor for our CNC.

So to do my first cut I have Used Onshape and Kiri Moto to generate a compatible NC program for our CNC

post processor from Fusion 360¶

I remembered I have used a post processor when I have Built a LowRider CNC from V1 engineering. I then went to their forum and Followed the instructions using flyfisher604 Post processor for Fusion 360.

This post processor support: * Marlin 2.0 * Repetier firmware 1.0.3 (not tested. Gcode is same as for Marlin) * GRBL 1.1 * RepRap firmware (Duet3d)

Installation:¶

The post processor consists of a single file, mpcnc.cps. It can be simply installed by selecting Manage->Post Library from theFusion 360menubar; alternatively the mpcnc.cps can be copied into a directory and selecting each time prior to a post operation. If there is an existing mpcnc.cps installed select it prior to installing and use the trash can icon to delete it The desired post processor can be selected during a post using the Setup button and selecting Use Personal Post Library Use the Job: CNC Firmware property to select between Marlin 2.x, Grbl 1.1 and RepRap firmware

Adding MPCNC post processor to Fusion 360¶

InFusion 360Manufacturing Mode; click on NC program in SETUP section (Step-01 in picture below)
Click on select post processor from library (Folder icon on Step-02 in picture bellow)
Next Click import in the library windows opened and click on import (Step-03)
Now In new File Explorer window will open prompting to select the post processor to import. Navigate to where you have extracted it and select it (Step-04); Now click Open (Step-05)
Make sur you clicked on the new post processor (Step-06) and click select (Step-07)
Since this post processor Code for different firmware I have to make sure while generating NcProgram or Gcode to select Grbl1.1 (Step-08).
