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). ![PXL_20231120_195823938~2](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/0/e/0ece337daaed0f83c1e0cd17a7e9a9e22453474f.jpeg) 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. ![PXL_20231120_213222744](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/5/1/5148d8cf7978b828896c42a04e9732581602fca6.jpeg) 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.
