Calibration

[zungara 10]

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 ?

Thanks for your fast response.

To point 3: I think about a filament holder. I am not shure which kind of filament holder is the best one.

Also you should look at your fan, that it is properly cooling and print at approx 190°C at the regular speed.

@Sander:

Yes, the fan is on. Should i disable the fan?
