We now need to tell Fusion 360 how to be kinder to it. We know our project machine, built mostly out of salvaged parts, is not a CNC powerhouse. Some examples include:įun fact: some other members of the GRBL CNC family include OpenBuilds, Shapeoko, BobsCNC and X-Carve – all starting just as the LongMill has from an Arduino Uno.In parallel with investigating points of weakness within the physical structure, we’re also learning how to make Autodesk Fusion 360 CAM friendlier to hobbyist grade CNC mills. If you’re interested, there have also been instances of LM community members putting their own post-processors to download.


A ‘post-processor’ is simply a set of rules that can be followed to add tweaks to the main g-code and ensure it’ll work for particular machines. For the LongMill and many other hobby CNCs, this dialect is known as “GRBL”. Doing so, how will you know that the g-code file is going to be properly suited to your particular CNC? Though many CNCs are able to interpret what’s broadly known as ‘g-code’, the reality is that different manufacturers have their own quirks that their machines expect to see you can think of this as g-code being the primary language while different CNCs speak with dialects or accents. When making gcode for any CNC machine, there will come a time where you’ll click the final button to “Generate Gcode”.
