Itty Bitty Double Extruder

[clough42]

Let's see a video of this thing printing! I'm looking forward to a dual extruder!

This is a live stream of a test print. It should be running for the next eight hours. Unless it fails utterly. After that, I'll come back and put in a better link and upload a time-lapse.

I'm printing this:

You can see the home/autolevel/priming sequence starting at 06:30. I'm using Roxy's enhanced G29 code.

Here's the startup sequence:

• Heat the bed
• Start heating the nozzles
• Home and probe for autolevel (G28/G29)
• Park at Z=0 with both nozzles off the glass
• Wait for both nozzles to reach temperature
• Prime the left nozzle wipe it onto the glass
• Prime the right, retract it slightly and wipe it onto the glass
• Print alternating loops (Slic3r)
• Print

Slic3r prints the outside ring with the left nozzle first; that's why I retract the right nozzle slightly. This keeps it from dribbling while the left nozzle prints loops. After that, Slic3r automatically handles the retracts.

Do you mind sharing all of that code. I'm using Roxy's Enhanced 29 too but I'd like to try the "parks" and "wipes", etc.
