Fusion 360 and Repetier Gcode

[Ken Snyder]

Has anyone used Fusion 360 to export CNC Mill Gcode for Repetier firmware?  What post processor did you use?  I've tried the MPCNC_Fusion360.cpc file, but the comments are the wrong style.

Thanks,

Ken

Ken,

If you are going to be at the meeting tonight I try to help you edit the post.

Hi Chris,

I can write a post processor but would really like to use one of the dozens that come with Fusion 360.  That way I'm not re-inventing the wheel or having to worry about distributing the processor to anyone wanting to use my big printer as a mill.  The gcode actually works, it's just that the generated comments are the wrong style.  Instead of "//" or "/* ... */" style comments, they need to be ";" semi-colon style.

Thanks,

Ken

It probably would not be to hard to modify the Repetier firmware to accept both.  I have not looked at that specific code, but it would probably take a OR statement where it reads the file.

That's a thought, but it might cause more problems with the 3D printing and laser etcher modes.  I'm still leaning towards fixing the MPCNC post processor but it isn't included in Fusion 360 either.  So I'd still need provide that too.  I was just hoping someone had already figured out which Fusion 360 milling gcode post processor out of the dozens already in there is the right one without having to try each one.  There's around 75 to choose from.  

The easiest thing might be to just modify or rewrite the MPCNC one and submit it to Autodesk to include with their distribution.  Does anyone know of a mill using the Repetier firmware?

You should try one of the linux emc posts because those are ";"  Not sure what differences will matter to you, since you are not using extrudes or heated bed when milling.  Tool call outs might not be recognized.

EMCs are on the list.  I'll try one and see if the tool commands are ok.  Repetier tries to execute the "//" and "/* ... */" comments instead of ignoring them.  I just commented them out with the ;'s and things worked fine.  

BTW Chris, I took your suggestion of getting a hanging grinder with a flex shaft.  It worked great.  I wired up a SSR to control the power and speed with the controller board via Gcode.  I printed a couple of mounts for live end, very similar to the aluminum hotend mounts you made for me.

I also created a 3D printed mount for a Dremel using the same carriage screws so people have options.  I haven't tried the heavier 500w spindle yet.
