A few months ago we received a Taz 5 with a few different extruders. I got the Dual Extruder v2 up and running fine with a single filament, but have decided to try my hand at my first dual extruded print. When I went to inspect the print heads, I noticed that Nozzle 1 (the one I had been printing with the most) was about 1-2mm lower than the other one. I figured what the hell, and tried a test print–knowing it wouldn’t work. As expected, the second nozzle was not low enough to adhere to anything.
What is the easiest I can get that nozzle back to where it needs to be? I tried heating up the print head and turning it with a wrench to no avail. Should I just try to lower the second nozzle to meet the first one?
Pictures attached. You can see the amount of space between the two when lowered to home.
I was skeptical I would be able to meet the clearance given the distance between the two, but the second nozzle is just barely close enough. Going to give it a calibration print and report back.
One problem is that nut in between the aluminum and printed brackets is just a hair too big. Would I be able to remove that entirely so I can lower the second nozzle even further?
Also, does the angle of the nozzles affect the print?
And we’re live! I had to fuss with the XY offsets quite a bit–realized I was entering the values wrong–but my first test print came out great! Looking forward to what I can achieve with this.
If I recall, the end of the screw was just below the top of the nut to get the nozzles level.
I created the attached thumbwheel to help with adjustment of the screw. Line up the interior hex and snap the thumbwheel on… might need pliers. The dual color provides a little more reference when adjusting.
