    OK so I am using an R1 And I have been trying to figure a way to calibrate the first layer I though at first I was too might but then I realized something when I tried to print an object with two bases.

    It seem the left side is binding the perimeters pretty well but the left side is way too spaced... Not sure how to fix this.

    The measurements I was getting were around 1.72-1.78.

    Inspired by your question I decided to use a different filament and I encountered a number of z-axis artifacts.

    Loose belt? Carriage issues?

    Looks more like a loose Y/X belt to me. If the belts that drive the X/Y are not tight then each layer of the print can have a bit of slop in that axis (making it uneven along those edges).

    Z axis would show up as thickness of each layer issues... those look pretty consistent.

    Yeah I am thinking X-axis is loose. Any tips on tightening it?

    Did it come with a clip on the x-belt?

    Yeah can it be adjusted? I thought it was a fixed tension.

    Do you have some zip ties you could use to replace the stock one?

    Yup, I clipped the zip ties by the base of the extruder assembly and pulled the belt tighter, then rezipped. Not sure how effective that was but it looks tighter.

    Print something :)
    You will quickly know I think, You can measure how tight the belt is by pushing on it and seeing how far it deflects. Sadly, it is not a hard and fast measurement, so it takes some practice to know when it is tight enough.

    remove the belt tensioner when you re-zip it. Then add the belt tensioner after it's as tight as you can get it.
