I mentioned the Kraken block was small, here are a couple of pictures of it next to an LM8UU. Obviously it’ll get a little taller once the nozzles are placed on it, which I’m working on. Just got some 8mm grub screws put in place, grabbing a water pump and doing a leak test while designing a carriage for it. Roy from Panucatt said he had some Azteeg “Pro” models coming in, which has electronics support for 4 stepper drivers. Release the plastic indeed.
How to control 4 extruders?
Hardware wise you could use 4 of these:

To bad there is no marlin firmware support, yet.
@Jean-Louis_Bourdon , http://e3d-online.com has preorders open for the Kraken.
@Jos_Scheepers that 50€ price tag is a joke, right?
@Thomas_Sanladerer
you can have 1 for free if you can get support for a 4th extruder in marlin 
Alright, alright, I’m finally off the fence and ordered one.
Is the Azteeg “Pro” what you are planning on using?
@Wayne_Friedt yep, Roy said they are still supposed to come in before christmas; I’m hoping that’s true. If that’s the case, I should be set. I have the rest of the hardware available to me @ DeltaMaker to experiment with.
