Fusion 360 Mill Post Processor for CNC12 with additional Features (New Community Version 1.0)

[spikee]

You could always throw in in a cnc simulator. But generally G-code is pretty simple. if you see junk it is generally something like what you expirienced.

A couple of questions regarding coolant options - I've recently begun using the mist command in addition to the flood command and have been choosing "Flood and mist" from the coolant dropdown in Fusion. HOWEVER it appears that no coolant commands are being written to the .nc file. When I was just using "Flood" an M8 command was being written. It appears there's a case statement for the coolant in the .cps file, but I'm not sure what the case conditional would be called for "Flood and mist"... Anyone have any ideas? I'm also not sure if that's the only snippet of code I'd need to add...

ALSO, because I've been using the flood and mist together I've had to activate them manually in CNC12, but sometimes it complains about the manual coolant activation and prompts me to change it back to auto before it will progress with the .nc file and therefore no flood or mist is possible...

Thanks in advance for any help!

I've posted a new version 5.2 of the PP at the bottom of the first post that includes some recent fixes:

• Rigid Tapping fix from Uwe (suntravel)

• Clamp M10/M11 fix. An M11 was added to the post even when the Property "Enable Clamp On/Off" was not selected

• Support to enable Flood and Mist Coolant at the same time (a M7 and M8 will be added to the G-Code)

cool, thanks, i changed this thread to a sticky post.

Just to confirm.... This newest post works with Rigid Tapping, but NOT rigid tapping with chip breaking?

I modified the post processor to add machine simulation. It basically involved copying some code from fusion and putting it inside. Other than that i have not modified the post code other than adding this.

Very cool

Thanks. That is very nice.

With respect to rigid "tapping with chip breaking", here is the error message you get (see attached). I am just starting to learn gcode so this is a bit above my pay grade.

Thanks... Richard

Sounds like a simular issue:

Perhaps the solution works

That is not working with Centroid.

I made a mod that makes Peck Tapping in fusion like the output from Intercon

Code: Select all

case "tapping-with-chip-breaking": // Uwe Peck Tapping
        
          if (!F) {
        
            F = tool.getTappingFeedrate();
        
          }
        
          writeBlock(
        
            gAbsIncModal.format(90), gCycleModal.format(84),gRetractModal.format(99),
        
            "X" + xyzFormat.format(x),
            "Y" + xyzFormat.format(y),
            "Z" + xyzFormat.format(cycle.stock - cycle.incrementalDepth),
            "R" + xyzFormat.format(cycle.retract),
            
            conditional((P > 0), "P" + secFormat.format(P)),
            pitchOutput.format(tool.getThreadPitch())      
        );

        for (var i=2;((cycle.stock - cycle.incrementalDepth * i)>(cycle.depth * -1));++i)
            if ((cycle.stock - cycle.incrementalDepth * i)>(cycle.depth * -1))
            {
              writeBlock( 
              "X" + xyzFormat.format(x),
              "Y" + xyzFormat.format(y),
              "Z" + xyzFormat.format(cycle.stock - cycle.incrementalDepth * i),   
               );
            }
          writeBlock(
            "X" + xyzFormat.format(x),
            "Y" + xyzFormat.format(y),
            "Z" + xyzFormat.format(cycle.depth * -1),
            gRetractModal.format(98)   
        );
      break;

It is using the Pecking Depth in fusion to increment till max depth is reached, starting each run at Feed Height.
