Fusion 360 Post Processor (v2.1) is Available

Release V2.1 of the Flyfisher604 F360 post processor is available.

Release History

----- Github tag: v2.1 -----

  • Enhancement: Custom gcode for coolant channels can be defined

----- Github tag: v2.0.1 -----

  • Bugfix: Undefined variable used for Z height during toolchange, garbage output

----- Github tag: v2 -----

  • Numerous bugfixes
  • Coolant channels reworked; allows for channels A and B to be enabled at the same time; allows a coolant type to be defined for a laser; coolant properties are unified to control either Marlin and Grbl firmware; warnings if tool’s requested coolant is not configured on a channel
  • SafeZ (G1 to G0 conversion) can reference the Heights defined in a tool operations
  • Enhanced comment levels
  • Firmware dialect selected as a property
  • Single file install via F360 standard Manage->Post Library install interface
  • Updated documentation

----- Github tag: v1 -----

  • G0 Rapid move at the beginning of each cut is restored - resolves tool drag when Z is not retracted before horizontal travel occurs (F360 Hobby issue)
  • Recovers G0 Rapids that occur above a safe height or that are vertical only (F360 Hobby issue)
  • Feedrates can be scaled to ensure mpcnc Z axis cut rate is not exceeded. Fusion 360 kinematics do not respect an axes feedrate if different from the machine’s generalized feedrate.


  • User must review all GCode produced to ensure it is appropriate for their needs.

Documentation for v2.1 may be found here .

Thanks heaps … I think I set this up right… I’ve used F360 in the past in DESIGN Mode but not manufacturing mode so hope this i s correct for setting up PP as per image attached.

Yes looks good. Make sure to review the docs and set the properties as needed.

Are you running a mpcnc off of the sd card option or a Octipi setup? Have any issues after using the processor through fusion? Im trying to narrow down my Sd card reading issue and seeing what others have come across with doing this.
When i added the processor to fusion it let me generate gcode. Saved the file with 1001.gcode, however when i try to run the file on the display its likes its not there or its not reading it.

Is this post processor suitable for a lowrider v3 as well?

Yes, it works fine with the Lowrider.
