Hi. There's a bug on how S3D slices and add the Tool Change Script.

A Tool Change should occur while changing the nozzle/color in the mid of the print.

I really don't know why the code should be executed BEFORE the start of the print, just after the Starting Script. That's a really bad behavior.

The software should give us the ability to choose if execute this piece of code during the startup or not, because it's NOT A STARTING SCRIPT.

The same for the layer change script. First Layer should not be considered as a layer change.

.... You know this?

Layer Change G-Code:
I personally haven't had to use this, but I'm sure that there are some excellent reasons/ideas to use for this. If you'd like for a G-Code script to be inserted in-between each layer, than you can simply place it in this tab. One interesting use of this, is for the FlashForge Dreamer, to have the lights blink in between each layer, however that can be a bit too much at times! The placeholders that are available for this tab are below:

[previous_Z_position]
[current_Z_position]

Tool Change G-Code:

This tab will insert G-Code on tool change commands. These commands can help do a ton of things for multiple extruder prints, especially if using the IF command functionality. For instance, if you wanted to change the temperature of your extruders (T0, and T1) for each tool change switch:

G28 X0 Y0; homes X-Y axis
{IF NEWTOOL=0}M104 S165 T1; set T1, inactive extruder to 165 C
{IF NEWTOOL=0}M109 S220 T0; Set T0, new active extruder to 220 and wait for it to reach temperature before proceeding.
{IF NEWTOOL=1}M109 S220 T1; set T1, Heat T1 to 220
{IF NEWTOOL=1}M104 S165 T0; Cool T0 to 165

If you were using one process (printed part with one extruder, support with the other), you would only need this script in your one process. However, if using multiple processes, you would need to copy+paste this into each process.

{IF OLDTOOL=0}G1 E-10 F1800 - this will only include the line that follows the {IF} brackets if the old tool (the one that was active prior to the tool change) is tool 0. You could use scripts like this to have different tool change retract distances for different tools
{IF NEWTOOL=0}G1 E10 F1800 - similar to the above command, however it checks the new tool (the one that will be active after the tool change)
[old_tool]
[new_tool]
[current_Z_position]
