G-Code

The G-Code tab looks like the following:

G-Code Options
Most of the options on this screen should be set once during initial configuration and then left alone. 

5D Firmware
What is this?
Provides support for X, Y, Z, F (speed), and E (Extrusion distance) parameters in G-Code. 

How do I use it?
Keep this option on. 

Relative Extrusion Distances
What is this?
Affects the behaviour of the E-axis - whether the extrusion distance counter is cumulative or not. 

How do I use it?
Keep this option off. 

Allow Zeroing of Extrusion Distances
What is this?
Allows the E counter to be reset to 0.

How do I use it?
Keep this option on. 

Use Independent Extruder Axes
What is this?
Certain firmwares track the extrusion rates individually. 

How do I use it?
Keep this option off. 

Include M101/M102/M103 Commands
What is this?
Provides support for legacy G-Code commands, not used in modern 3D Printing firmwares. 

How do I use it?
Keep this option off. 

Firmware Supports "Sticky" Parameters
What is this?
Sticky parameters allow non-explicit setting of speed parameters

How do I use it?
Keep this option on. 

Apply Toolhead Offsets to G-Code Coordinates
What is this?
Enables use of the Toolhead Offsets feature. 

How do I use it?
Keep this option off. 

Global G-Code Offsets

Offset
What is this?
Provides a virtual co-ordinate offset to compensate for hardware changes.

How do I use it?
For the most part, you will only need to use the Z-axis offset - if your nozzle spacing is off by a small amount but you do not want to manually level the bed, you can apply a positive value here to increase the spacing between the nozzle and the bed, or vice-versa. 

Update Machine Definition
If you are running several different 3D printers, check this option to have Simplify3D automatically update the basic configuration via the process settings instead of manually inputting the changes every time. 

Machine Type
What is this?
Selects either Cartesian (XYZ rectangular) or Delta (circular) configurations for the 3D printer. 

How do I use it?
Should be set to Cartesian. 

Build Volume/Origin Offset
What is this?
Sets the build volume of your printer, updates the size of the virtual workspace accordingly. 

How do I use it?
X should be 454mm with -62.5mm offset, Y should be 454mm with 0 offset, Z should be 640mm with 0 offset. 

Homing Direction
What is this?
Which direction the axes move to go to the zero/home position. 

How do I use it?
All axes should be set to Min. 

Flip Build Table Axis
What is this?
Sets the positive/negative directions for the axes. 

How do I use it?
Y should have a flipped axis, default for X and Z.

Toolhead Offsets
What is this?
For multiple extruders, sets the offset distance between them, using Tool 0 as the (0,0) origin. 

How do I use it?
The AON-M handles tool changes at the firmware-level. Do not use this feature. 

Update Firmware Configuration

Firmware Type
What is this?
Sets the class of firmware and corresponding compatibility with G-Code. 

How do I use it?
Set to RepRap. 

Baud Rate
What is this?
Sets the serial USB bitrate. 

How do I use it?
Set to 250000.
