FYI
This is the error message I got When I tried to do a laser cut Using the plasma Postprocessor 


Error: The CNC does not support the required tool/process. Only plasma cutting is supported.
Error at line : 281
Error in operation: 'circle'

Thanks for the info Chuck.

this might be old, but I'm stumbling through the learning curve- the mach 4 mill post processor doesnt support laser toolpaths, at least according to the error code I keep getting in Fusion. there doesnt appear to be a laser compatable mach 4 post processor in existence, should I be using the "laser compatable" mach 3 post you linked here ? with all the updates fusion has done since your post here, is that processor still valid?

Seth at liberty machine wrote the MACH3 laser post processor.

Since the M codes are different for laser on and off in MACH4,  those changes would need to be reflected in the post processor.

not sure what that means, sorry. you're saying I can take the mach 3 laser file you made and edit it? or are you saying there is a mach 4 laser post processer out there that I'm not seeing? autodesk's processor files only show mach 4 milling, and that post file has no text within it regarding lasers, and will not post the toolpath in fusion when I try and post it.

MACH 4 uses M 62P1 and M 63P1 for laser control. MACH3 uses M 10 P1 and M 11 P1.

Within the post processor these need to be changed by somebody that’s familiar with the post processor language.

But... that's why I'm here... I have no clue how to do this stuff. You're saying mach 4 does the laser on / off, but there is no post processor that can translate fusion's laser on / off toolpath commands to M62p1 and 63? so I'd have to either take the working mach 3 one and change the processor to spit out those codes, or find someone who can alter the mach 4 processor from scratch?

This seems like an AutoDesk failure. but I'm also confused cause I CANT be the only guy out there trying to get a diode laser working on a router style CNC using mach 4 and an ethernet smooth stepper... someone is getting this done. somehow.

Contact fusion 360 and see if they will do it.

As a temporary ‘workaround’ until you get a post processor sorted, it is no real problem to use Notepad ‘Find and Replace’ function to automatically change every M11P1 to M62P1 and then every M10P1 to M63P1 (or whatever P#) to convert a Mach3 laser Gcode to a Mach4 laser Gcode.
