Introduction

Use Fusion360 to generate laser toolpaths for your BoXZY

Video Overview

  1. Fusion360 needs a modified post processor to successfully communicate with the Boxzy firmware Just about any laser post processor can be modified for Boxzy firmware, but the smoothie post processor already has the basic foundation and necessary elements This guide will show you how to download and install the modified smoothie post processor.

    • Just about any laser post processor can be modified for Boxzy firmware, but the smoothie post processor already has the basic foundation and necessary elements

    • This guide will show you how to download and install the modified smoothie post processor.

    • smoothie boxzy laser rev01.cps

    • If you are interested, the README.md file provides a basic overview of the revisions.

  3. The best way to find the folder location of the post processor files on your machine (and to test the modified code on your machine) is to make a simple sample burn. My sacrificial material is some thin cardboard 0.7mm thick

    • My sacrificial material is some thin cardboard 0.7mm thick

    • Open Fusion360

    • Start a sketch; draw a small square; and extrude it. I made my sample 40 x 40 x 0.7mm and located 10mm from home on both X and Y

  4. Switch to Manufacture  mode Under "Cutting" menu, create new 2D profile Tool:  Select a laser tool from sample library or your own laser tool that you set up previously
    • Switch to Manufacture mode

    • Under "Cutting" menu, create new 2D profile

    • Tool: Select a laser tool from sample library or your own laser tool that you set up previously

    • Geometry: Face of square

    • Top Height: Model top with 50.7mm offset (or the focal length of your laser)

    • Retract and clearance height can be set to top height

    • Compensation type: In Computer

    • Click OK to generate a toolpath

  5. At this point, you should have a valid toolpath To install the modified post processor on your computer, right click on the setup and click Post Process Once the Post Process window appears, copy the folder location of the Post Processor files as seen at the top of the window
    • At this point, you should have a valid toolpath

    • To install the modified post processor on your computer, right click on the setup and click Post Process

    • Once the Post Process window appears, copy the folder location of the Post Processor files as seen at the top of the window

    • Open that folder location in Windows Explorer and save the downloaded "smoothie boxzy laser rev01.cps" file into that folder location

    • When you next open the post processor, the modified smoothie processor should be an option.

    • If not, you may need to close the post processor and reopen. Or you may need to close the model and reopen. Or you may need to close F360 and reopen

  6. Your machine should now have the modified post processor installed. Post process with the modified "smoothie boxzy laser rev01.cps" processor to a .nc file. In the Boxzy interface, load the .nc file by pressing the "+" button like you normally would for a 3D model.

    • By default, smoothie inserts some G28 commands at the beginning and end of the program. If you do not want that, comment those out in Boxzy's gcode editor.

    • When you think you are ready, home all axes and burn it.
