@deckingman Yes, not easy, anyone can do easy. S3D can send scripts for certain events:

• pre and post layer change
• pre and post tool change
• and others probably not relevant.

I'd like to avoid using those scripts in favor of creating a macro.
Would it be possible to create a macro riding over the firmware to translate "switch to Tool1" into:
-Park current tool;
-use steppers U/V <I'm guessing here>;
-change or adjust to z-Offset difference;
-change bed tilt <this assumes it will be near impossible to get both gantries on same plane> ;
-use tool1;
-wipe new current tool;
-go.
-->I'm sure I have semantics wrong, nevertheless..
Where's a good place to look for a reference on doing that?

-Thanks again.

@deckingman With Simplify3D, you can assign which tool is used for support. My IDEX printer can do that - main filament on tool0 with support in tool1.
Otherwise you'd be correct if I wanted two colors. Each color has it's own stl.
Unfortunately my IDEX, at one time a very nice printer, is showing it's technological age.

@dc42 Good-thanks, now the "in the weeds" question. Does each extruder/gantry need to be level and on the same plane as the other? Or can each have it's own z-offset and QGL/bed tilt?
I'm unaware of any DIY projects allowing manual adjustment of gantry level and/or nozzle height.

@deckingman Sure, I tried to keep it clear and missed that bit. The first part, single object each extruder printing seperate parts of the object.
Or:
Printing ABS on tool0 and HIPPS on tool1, filament and support.

I'm looking for ideas/direction on a dual gantry "CoreXY" firmware for a basic printer I'm cobbling up.

Simply put, this means two extruders on seperate gantries printing one object. I have an IDEX printer but it is slow and not very precise. The DIY tool changers I've seen seem slow and I expect not as accurate I'd like. The ERCF project will be excruciatingly slow. Hopefully I'm not asking for too much.

I have a design in mind, with parts on order. It'll be a mashup of other tried and true printers with a 2nd gantry and steppers thrown in.

If you can offer links, tips and/or advice that would be great.

I need some tips on where to look and what to look for, thanks.

Background: I've been using Klipper for my CoreXY printer and I think this dual gantry setup is not supported or planned. I may be wrong about that.
