Here’s my first two color print from an E3D Cyclops driven by two BondTech QR extruders. Up until I got the QR extruders last week, I was unable to get a complete print (using modified, geared stepper ezStruders). These photos are a testament to three great pieces of kit: the E3D Online Cyclops hot end and the BondTech QR extruder and the Taz of course.
My Taz (KITTazz) was modified with an FSR under-bed sensor system for auto calibration. The 3 FSRs define the bed’s plane. I print on PEI exclusively. And I updated to Repetier firmware (the latest) since it supports a really nice multi-extrusion capability and the type of auto calibration that I wanted.
For this print I took a guess at slicing parameters. I couldn’t be happier with a first effort. This bronze colored PLA filament is very picky - it shows every extrusion flaw (something to do with its reflectivity I think). The part in hand looks fantastic.
This was sliced with KISSslicer 1.5 beta 2.20 on OS X for my Lulzpot Taz 4 printer with a Cyclops dual hot end (2 filaments in-1 nozzle out). 1.75mm PLA filament. Here’s the basics:
.4mm extrusion width (.4mm nozzle)
3 loops/perimeters printed inside to outside
33% straight infill
3mm prime and suck (retract)at 25mm/s
205°C temp / 55°C heated bed on PEI print surface
Printed at 40mm/s, first layer at 22mm/s
No extra retract for filament change since that can cause problems with the Cyclops as I discovered with trying Simplify3D (which by default did 12mm retract and caused the Cyclops to jam after 3 layers every time!).
