Uneven line during first layer calibration

Hello all, 

I currently have an issue with one of my minis with was running fine for years that I don't know how to solve:

I notice some gap in thin wall (2 perimeters) on one side of the print, so I did the first layer calibration to see if everything was ok and I noticed that line going from right to left were larger than line from left to right. 
I then did a calibration cube to check the layer width and on the 20x20 vase cube I have .50mm on the left and .35 on the right side.

The PTFE heartbreak tube is new same as the nozzle, I do maintenance regularly as it prints almost every day. 

Does anyone have an idea from where this issue can come ? 

Thanks

!

So after searching on internet everything around this issue, I found the problem it came from the Extruder-Hotend PTFE tube which was all worn out I guess from the filament sliding inside and the left-right movement. I try with another one and everything looks good now.

Problem solved !

RE: Uneven line during first layer calibration

@Mryck - are you referring to the longer tube that goes from the extrude to the hot-end or the short tube inside the hotend?
