Hey AutoWiz!
"I've already been picked on for its chunkiness. "
Yeah, well forget them. I love it for all it's chunkiness!
There's a real Rube Goldberg feel to it, and I think you did a great job. Fine tuning is always the end step, and Version 2 will be better.

You DO know you'll build a Version 2 don't you? You don't have a choice, it's in your genes to tinker, just like me. LOL

Keep us up on it as you go. Did you get a chance to single it up and test the extruders ?
I'll only be around sporadically, but you've got me watching with anticipation to see for Frankenstein can walk! (Said with the greatest love for your creation!)

Keep plugging, you'll get there.
