Smoothieboard + Dual Extruders. :-)
Posted: Sat May 17, 2014 9:48 pm
So, I've been working with the smoothieboard guys to work out the kinks in the multi extruder code, and it looks like we've got it figured it out.
Go ahead and take a look at the config file to see how it's set up.
The soluton is extendable to X number of extruders, memory and pins permitting.
So it should work for your Kraken folks as well.
For now, make sure your slicer is set to use "5G - Absolute" coordinates.
this branch doesn't handle offsets correctly if your slicer is generating relative code, for now.

You can pull the source files from here:
https://github.com/logxen/Smoothie/tree/multitool
also attached the zipped up firmware file.
This firmware merges the latest edge branch with loxgen's multitool branch. I'm in the process of dialing in the offsets using a simple test file, and then I guess my first multi material print!
(I'm so tired of removing support material, I have high hopes that ABS + HIPS will solve that for me)
Here is the config file I'm using:
