My first print with my new Dual extrusion KIT work. But the result is not as good i expected.

1. the not aktive hot end loses less material. so i get a shadow print

2. sometimes one hot end scratch over printed structures

I think i have an calibration problem. I tryed to make it like described, but i am not shure because i had some problems to adjust the printhead. The long screws with the black spacer are strong to move.

3. What is a good idea to handle the second filament? I use mostly 2 KG PLA

try putting up the amount of retraction on the expert settings in cura..

you do have to spend some time to calibrate, so the two tips of the hotend are evenly touching the bed with little to no change in height..

i designed little finger screws on m3 nuts to help me with this and they seem to work great to get a perfect setup :-)

what do you mean in this ?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
