I was wondering if you can help me with this? I set up my machine but the G-Code does not print the machine. What am I missing? I have generated G-Code but when I load it into the machine the printer does not do anything. Do I need to re-flash the printer firmware or something?
Second issue is once I get it to work will I be able to load start up G-Code?

Hi @Scott.bender ,
I don't see any need to flash the firmware by default.
We tested the post on a Lulzbot printer owned by an Autodesk employee.
But I can't find out which model, I will ask another colleague to be sure.
But let's take a look at a gcode, and define what it should do, and maybe we will figure out what is happening.
Fusion
G21
G90
G26
M82
G28 X0 Y0
G28 Z0
M117 Heating...
M400
;--------------------------------
;Selected Profile: PLA 2.85mm, 0.4mm Nozzle
;Selected Printer: Autodesk, Generic FFF Machine
;--------------------------------
M140 S60
M190 S60
M104 S220 T0
M109 S220 T0
G1 Z10 F6000
M204 S100
G29
M420 S1
M425 Z
M425 Z F0
M204 S500
G1
G1 X0 Y0
G92 E0
M117 Printing...
So what this code should do:
G21 Define the unit as millimeter
G90 Set the printer in absolute coodinate mode
G26 Validating the mesh !!! It may fail ?
M82 Absolute filament length
G28 X0 Y0 Move to XY home position
G28 Z0 Move to Z home position
M117 Heating... Should display a message on the printer LCD
M400 Wait till all moves are completed
;--------------------------------
;Selected Profile: PLA 2.85mm, 0.4mm Nozzle
;Selected Printer: Autodesk, Generic FFF Machine
;--------------------------------
M140 S60 Heating the bed to temperature (60° in this example)
M190 S60 Wait for the bed reaching 60°
M104 S220 T0 Heating the hot end to 220°C (in my example)
M109 S220 T0 Wait for the extruder reaching 220°
G1 Z10 F6000 Plunge in Z
M204 S100 Change probe acceleration
G29 Probe bed
M420 S1 Activate the mesh
M425 Z Set the backlash compensation
M425 Z F0 Turn it off
M204 S500 Set acceleration for depositing
G1
G1 X0 Y0 Move to position for priming
G92 E0 Reset filament counter
M117 Printing... Display a message on the printer LCD
If you can see the message Heating, it means the G26 does not caused issue.
If you can check the temperature and see them rising, that's good.
If it display the printing message the rest should no cause any issue.
Can you try again, and report the behavior on your printer, please?
(Does it display the messages, does it heat up ? ...)
We will then be able to guess what's going on.
Regards.

Maybe if this area in the Machine Config edit point there is a section to add Start and stop G-code?
Hello @Scott.bender
The Fusion 360 post processor, for additive fff, or subtractive, are some .cps files, written in JavaScript.
It can be edited using any text editor, but we recommend using VS Code, and the "Autodesk Fusion 360 Post Processor Utility".
It can be downloaded from the VSCode app store.
A manual describing the skeleton of the post, its functions, and variables can be found online:
https://cam.autodesk.com/posts/posts/guides/Post%20Processor%20Training%20Guide.pdf
The only other way to modify a post, is using the add-in available on the Fusion360 app store, called Additive FFF post Configurator:
https://apps.autodesk.com/FUSION/en/Detail/Index?id=7510560621924796173&appLang=en&os=Mac
Nothing can be done from the print settings.
Comparing the two headers :
The commands are not in the exact same order, but I don’t see any reason for the problem, because of the command order.
Three points can be causing the trouble.
We are outputting the M400 (end all moves command) sooner than your slicer.
But it's only flushing the move buffer before proceeding further.
Second point we are using M104 for setting the extruder temperature, then M109 to wait for this temperature to be reach.
M104 is not used in your header!
Third point, all our wait for temperature commands (M109 and M190) uses S prefix for the temperature. (Wait until heating)
Whereas your header is using R prefix (wait until heating and cooling)

Ok I think I got somewhere. It's not perfect but I think the lulzbot .cps posting for the TAZ Pro isn't inputing the start auto leveling sequence. I got it working by copy pasting the Cura code for start up into the Fusion post GCode via the Visual Studio Code program.
Thoughts?
Hello @Scott.bender
If you have copied, moved, renamed the post, also check the machine configuration file you are using.
Copy the regular machine config file for the lulzbot taz6, to a local or cloud personal folder, in the machine library.
Then edit and check, or fix if needed, the post link and settings.
We are using internally the printer model, to define if we output the bed levelling commands, or not.
It's done for the mini, mini2 and taz6 model only.
Regards.
