We have recently acquired an Omio CNC router and wanted to use it with Autodesk Inventor/HSM Ultimate plug-in or Autodesk Fusion 360. I am new to CNC router, so bare with me for my ignorance in this area. I have created our team logo as our first CNC engraving project using Fusion 360. When trying to generate G code, Fusion 360 was asking me to pick a machine from its list. And of course, Omio is not on the list. I have played with an old Shapeoko CNC router (from Sparkfun) before so I pick Carbide 3D from the list (Shapeoko is basically a Carbide 3D machine). My rationale for picking Carbide 3D is that I used CarbideCreate software and created the same team logo project on it. I fed the resulted G code generated by CarbideCreate directly to the Omio CNC router and it executed the G code beautifully. So I know the G code for the Shapeoko is perfectly compatible with Omio. But when I finally using Fusion 360 to create the same logo, the resulted G code caused some issues with the Omio machine. When it executed the G code, the machine first executed the “HOME” command (G28). When the machine was “homed”, all three limit switches (X/Y/Z) were engaged and the machine stopped. Then the machine proceeded to move to the “zeroed origin”. It moved in the Y axis less than an inch and the whole machine stopped with a non-stop beeping with the X and Z limit switches still engaged. From previous experimentation, the same non-stop beeping would happen if I manually control the gantry to move to the extreme left (X-axis) and engaged the X limit switch. I even commented out the G28 command (“HOME”). The machine doesn’t “HOME” any more, but when trying to move the zeroed origin, it stopped again and gave me the non-stop beep. Then I thought may be I shouldn’t pick the Carbide 3D as the machine in Fusion 360. But then what should I pick since Omio is not on the list. I found an entry “Othermill” on the list. Don’t know if it is actually a brand name or it meant “any other milling machine”. In any case, I picked that and regenerated the G code. The same thing would happen. The machine stopped with a non-stop beep after the HOMING operation.
Does anyone know what is causing this issue? If it helps and you have an Omio machine, I can send you the generated G code so you can try it and let me know what’s wrong with the code.
