Very Cool! Looks great!

It is something that I have been meaning to try. How did the layers bond? Easily? Is it ABS or PLA? Did you just guess at which layer to pause it or did you watch the print and pause it manually where you wanted to change over?

Nice.

I've had similar results using Up-Box with 2.17 using the "pause at height" feature then swapping colours. I use if for signs and the like whereby the base is one colour and the letters another.

I've only tried printing in ABS and bonding is fine. Only tried swapping as soon as it's paused, not letting it cool and then starting again.

Also had a play with pausing the print to insert nuts into pockets into the print then resuming to have proper captive metal threaded fittings. This works but is a bit of a pain. Inserting the nuts with the build plate in the machine is tricky, and if the plate is removed it bows to hell and is then really hard to replace in the UP-box. Alignment also hard as the perfboard seems to seat differently when hot vs/cold. Also the damn software won't let us prevent supports for the cap of the nuts being created (as it doesn't know a nut will be there). So they have to be picked out before inserting the nuts...

Overall worth the effort though.

By the by there is a nice kickstarter project that allows one filament to be withdrawn and a different on inserted by a pair of steppers, so dual colour printing with just one extruder, as a retro fit bolt on to existing printers.

Cheers,

Owen S.
