Got a video printing with it yet though?
@Tim_Rastall , I could probably whip up a post-processing script in Python? Matter if it includes borders? Should be as simple as doing a T0, T1, T2 and then offsetting the gcode by the nozzle offset, right?
@Ben_Van_Den_Broeck
@Joshua_Rowley has been doing a lot of taking it apart and putting it back together, as well as software nonsense in a very piecemeal way at the moment. Nothing video worthy.
I am also completely stripped of time right now, as I am finishing up my job as a school teacher and need to make sure that I am leaving things in a way that my kids I am leaving behind won’t be disadvantaged. School in the day and E3D in the evening is gruelling, and I’m barely keeping my head above water on the basics like answering customer questions.
I have a really cool idea for what I want to print for our first video appearance, taking full advantage of being able to print multi-materials in a functional way. It’s just going to have to wait until after December 13th when I break up from school.
I’m fairly sure @Tim_Rastall or @Richard_Horne will beat me to the punch!
Can u post de dims of it so we can design mounts for our machines?
@Bob_Rosania
We’re doing a single tweak to change the threads on the water cooling system away from M8 threads which don’t seal easily, towards 1/8th" BSP which is a pipe thread and also compatible with computer cooling systems.
This may have some small implications for the placement of the mounting holes.
In the mean time I rustled this up:
Which should give you an idea of how things are set up - but it would be prudent to design mounts in a parametric way as small tweaks are likely.
@Sanjay_Mortimer What controller are you using for 4 print heads? It just dawned on me that my RAMBo supports only 2.
Derp. XD
I should have 2 nozzles running this week and 3 the week after. HIPS supports with 2 nozzles and multimateral infill with 3+nozzles. Will post a video as soon. As it’s doing multinozzle stuff. With 1 nozzle it prints just the same as a vanilla E3D HE 
@Nathan_Ryan We are using RAMPS (2x Extruder) and RUMBA (3x Extruder)
It looks like both can be expanded to take extra extruders via the AUX ports, and we are going to be breadboarding solutions for doing that.
I expect a fairly simple add-on PCB that just plugs into the aux port with a neat ribbon cable will be the final solution. Should be a fairly simple and cheap board too.
Another option is just to buy another RAMPS shield, (Only $25!) and slave it to your current board. Added bonuses here are that the RAMPS board is proven, contains the FETs, thermistor balancing resistors, and driver sockets you need. It also means you have a RAMPS board on hand, which is no bad thing.
@ThantiK . It would need to exclude perimeters as they should all be ABS. For the time being I can just Brute force some gcode with excel macros (or whatever) if I use kiss as it annotates all the infill moves.
Long run, slicers should be able to do this as the opportunities that Kraken presents for material composites are very exciting,
