Hyrel 3D E5 - Quad Extruder Printer

[Geoff]

Geoff,

Actually, every printer already comes with a camera built in under the yoke. The microscope is for closer inspections.

I'd be interested to hear how you do four materials at the same time with just the two heads. Our 1.75mm filament heads are $250 each when purchased individually.

Sorry, I meant two at the same time, I wasn't suggesting I can get 2 nozzles to print 4 items simultaneously. The camera built in is a plus.

I would like to know how you guys avoid 4 nozzles dragging across eachother prints, even with 2 heads it can be a challenge. Let's say you wanted to print a very large object in one colour on your machine, would I need to remove the 3 other heads? or what is the variance on each nozzle height?
