Fusion 360 CAM Gcode for DuetWifi
-
Are there specific settings i need to set in Fusion 360/gcode processor for it to output compatible gcode for the DuetWifi (1.21R4)?
Should i be using a specific preset?
-
Anyone know?
-
To me it looks like you could use the Mach2Mill or Mach3Mill post. Maybe even the LinexCNC post?
I would try some of them to see what the program looks like when generated. The adjust the post processor to suite what you need.
I will be building a 5 axis CNC mill starting in the fall and plan on using a Duetwifi board to control it. But I won't be much help until then, Sorry.
I do use the Fanuc/ fanuc post for my big CNC mills at work but they all have Fanuc controls on them.

Ok I have outputted three sets of NC Gcode, using three post processors that are available from autodesk

0_1525010451420_GRBL test 1001.txtThey all seem quite different, not sure which i should try first. the reprap seems least likely to work based on the "N" series of GCode commands.
I dont see those listed in the Duet3D gcode list

Looking at GRBL Code
Here are some Commands that i dont see in the Duet3D Gcode listG94
G17
M9
M6 -
Looking at Reprap code
Here are some Commands that i dont see in the Duet3D Gcode list so farM9
M8These seem to be
M8: Flood Coolant On (CNC specific)
M9: Coolant Off (CNC specific) -
Does your CNC machine have a flood coolant facility?
-
no, this is something i need to disable in the CAM settings,
-
RepRapFirmware will warn you if you try to use unsupported GCodes, but other than that they do no harm.

Ok i tried to run the reprap Gcode
this is the error received
M32 "RepRap Test 1001.NC"
File RepRap Test 1001.NC selected for printing
Error: Bad command: %
Error: Bad command: [[language]]
Error: Bad command: [[language]]
Cancelled printing file RepRap Test 1001.NC, print time was 0h 0m
Error: G0/G1: outside machine limitsalso under machine control, it says X&Y is not homed
Can I tell it that current position is home? via a macro? -
You can tell it that the printer has been homed and where the tool head is using the G92 command.
-
no sorry, what i meant was.. can you run a command/macro to tell machine is has already been homed to bypass homing check.
-
@adamfilip yes use G92
So it when its in the home position, you have the head at X0,Y0,Z0 then use G92 X0 Y0 Z0
If you have it homed at a different point adjust G92 as required.
-
Just what maybe a stupid observation but the Filename you have is .NC could it be that that is throwing it of most files (If not all) that we print have the .gcode extension. Remember that F360 Cam module is meant for CNC Machines rather than printers.
Now I may well be way of the mark with the obstacles mind but I thought it worth mentioning David is prob the man to either discount or whatever on the observation.

The firmware doesn't care what the file extension is. DWC does care to some extent, for example when presenting you with a file upload dialogue.
The "%" character is mentioned in the NIST GCode standard:
"The RS274/NGC language has no indicator for the start of a program. The Interpreter, however,
deals with files. A single program may be in a single file, or a program may be spread across
several files. A file may demarcated with percents in the following way. The first non-blank line of
a file may contain nothing but a percent sign, “%”, possibly surrounded by white space, and later
in the file (normally at the end of the file) there may be a similar line. Demarcating a file with
percents is optional if the file has an M2 or M30 in it, but is required if not. An error will be
signalled if a file has a percent line at the beginning but not at the end. The useful contents of a file
demarcated by percents stop after the second percent line. Anything after that is ignored."I may change RRF to recognise these %-lines.
