Dual Extruder Calibration, X axis Issue

Greetings all. I have crept around here and there and also tried to find this issue already here on the boards, but to no avail.

When I try to calibrate my x/y axis, the x axis always prints the second layer calibration line to the completely to the left of the first layer calibration line (see below).

I have set my X setting all the way to the left, because “comb” is the closest to center. See the red arrow. The result is the calibration cube above, and my x axis is still .63 mm to the right of the rest of the cube. The red arrow points at this overhang on the cube.

I have the quick swap kit and I did have the problem both before and after I installed it. As far as I can tell, the kit is in the right position from the install guides.

Any ideas on what I can do to fix this?

Thanks,
Kap

Also forgot to mention that Z and Y work perfectly and have no issues calibrating.

There are mentions of one of the two extruders getting loose - if you wiggle yours a bit, do they feel solidly fixed, or is there play?

Oh, I had not noticed that. The left extruder, the one that is off wiggles a lot. Is there a fix for this? I already installed the fix kit, which really helped the clogging issues.

Honestly, I never checked if there is an official solution to that problem. My assumption would be that some screws got loose - tighten them and you should be done; but as I said, just an assumption, I may be completely wrong here.

Thank you for the reply! I submitted a ticket. There are indeed some screws that I will need to tighten. I got a pic of them, but I am not sure how to get to them for sure. I will start out by following the guide to intstall the repair kit.

The ended up sending me a new linear rail for the left nozzle in the DX. Replaced it and finally got a good print for the xy calibration. Printing a new Calibration Cube now to see if I finally got everything working right.

May share the guide in this thread? Thx!

Yes please do. Here is the link they sent me that shows how to replace the linear rail.
