First dual extrusion print from a Cyclops hot end and BondTech QR extruders

Post by mhackney » Mon Dec 07, 2015 3:17 pm

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:

.2mm layers
.4mm extrusion width (.4mm nozzle)
3 loops/perimeters printed inside to outside
.6mm skin
33% straight infill
3mm prime and suck (retract)at 25mm/s
5mm wipe
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!).

That looks great! Very clean transitions between extruders.

Yes, I'm *really* pleased and excited. I've been dabbling in dual and triple extrusion for a few years and this is by far the most promising result I've had.

I would love to see a video of this thing printing!

I'll shoot some video the next time but I'm NOT videoing the entire 5 hours of print!

I don't blame you on that one. Just would like to see the switch between colors and what not. Do you notice any oozing/stringing being you are using 1 nozzle along with 2 bowden?

If the part is sliced in KISS, no. If in S3D I have lots of problems. It is not handling the switch over very well and there don't appear to be parameters to adjust that. There are a couple of others who reported this too. It's a bummer as I'd like to use a different color for infills than shells to do things like this:

Here's the next thing I'm working on, a technique to print logos and inscriptions in 2 colors on my 3D printed fly reels using the E3D Cyclops 2 color switching hot end and BondTech QR extruders. This is a first attempt and is about 95% of the way there. Just a few refinements and it should be ready to go. This one is done in translucent smoke PLA in clear PLA. The logo is three .2mm thick layers.
