Printed on my primary M2 + Simplify3D. First time trying out changing colors mid-print and worked perfectly

I don't know what Starcraft is, but those came out great.

Nice job.

Very nice!

Neat! How did you do the filament switch?

Was pretty easy - in S3D, I just checked the "Stop printing at height" option to the layer right before the logo starts printing (was something like 2.40mm). Then after it ran through my normal ending gcode, I kept the fans/heaters on, changed filament, then UNchecked "Stop printing at height" and checked "Start printing at height" set to 2.40mm. The print then continued, but this time starting at the logo height on top of what I had already printed.

If you printed these one-by-one, there's an easier way: viewtopic.php?f=3&t=2729&p=16725

That's the technique I used for this:

Thanks for the heads up on that - my method was quite simple though and needed to be single-layer accurate. Guessing where to splice in the 2nd layer filament would have been way more trial & error. I can see your method being good for when you are running out of filament for sure though.

I wasn't sure whether ending the print using the S3D and restarting at the layer where you left off would work or not...glad to hear it does. Steve has written up a way to preset a pause into your G-code that works really well - lets you stop the print, switch out the filament, and then resume without having to shut everything down first:

G91 ; set relative positioning
G0 Z40 ; raise Z (drop bed)
G90 ; set absolute positioning
M84 S0 ; disable idle timeout
M25 ; Pause SD Print
G92 E0 ; zero extruder

Just drop that code in right at the layer that you want to pause on. It gives you the opportunity to manually purge the old filament out and prime the new one, so the layer change occurs exactly where you want it to - his write-up is here:

Thanks for that as well Jules! Yes, S3D is as easy as checking a single checkbox & indicating what layer height you want to stop at. Then when that is done, check the checkbox in your S3D process to start on the same layer height...and done. Super easy.

Cool! Gonna try that!
