My apologies, I thought this was a comment on the other answer, but now see that it is more related to the question and is in fact an answer. +1 for remarking that what the OP intends is not what can be done (printing independently with the 2 nozzles as there is just one carriage).

<p>I'm playing with the QiDi Print software to compare the slicing results with mine (Dremel 3D45). One of the reasons I'm going to buy it (QiDi i-Fast) is the printing in parallel using the two nozzles:</p>

<li>load the objects (two instances of the same or even two different objects)</li>
<li>select the left one and press &quot;print with extruder 2&quot;</li>
<li>select the right one and press &quot;print with extruder 1&quot;</li>

# QiDi i-Fast print in parallel

(Asked by: username_0 on 2023-02-14)

I'm playing with the QiDi Print software to compare the slicing results with mine (Dremel 3D45). One of the reasons I'm going to buy it (QiDi i-Fast) is the printing in parallel using the two nozzles:

But I'm not able to set up the slicer correctly. As an example I set both extruders with the same PLA. I did the following steps:

1. load the objects (two instances of the same or even two different objects)
2. select the left one and press "print with extruder 2"
3. select the right one and press "print with extruder 1"
4. in the slicer parameters window, if I try to set the extruder for build plate adhesion it is set for *both* extruders:

Finally, how to set up the slicer in order to print two objects in parallel?

The question regarding the wall is covered in the advanced settings for Additions. In the screen capture above, you can see that it is turned on. Ostensibly, it's used to scrub off the previous filament oozing as it sits idle.

I don't have an i-fast and cannot identify the setting you require for duplication printing. Terminology is tricky; my IDEX printer slicer calls it duplication printing and mirror printing.

It's not an IDEX, meaning they're not independent extruders. It has two connected extruders in one printhead, it can't do IDEX things, it can print with two different filaments, one at time.
