Changing extruders at a given layer

[chuck-yanke 10]

I have been playing with HueForge. You change filament at given layers to create colored prints. Is there a way to start with extruder #1 and at a given height switch to extruder #2. I know both will be have to be AA. I could manually insert a filament change in the G-code for extruder#1. I was trying to automate it. the switch.  I do not want to have to create multiple stls and merge them.

I'm not fortunate enough to have a multi-extruder printer so I'm sorry I can't be more help. But I do know that if nothing else, you could manually edit the gcode to do it.

-Add a support blocker block

-Go to "Per model settings"

-Set it to "Modify settings for Overlaps"

-In the drop-down menu below it, set it to "Cutting Mesh"

-In the bottom left corner, while having your "support blocker" block still selected, select your second extruder

-Scale the "support blocker" to your required size, and set it to your required X/Y/Z

 

That should print everything in the area you marked with your 2nd extruder.

 

I call it a "support blocker" because it loses that functionality if you set it like this in the per-model settings.

When I'm doing that, I call it a modifier mesh.

That does make a lot more sense, I just kept the name the same since Cura still lists it as an "Eraser" object if you don't rename it manually
