A quick Print to use for calibration or figure out ratios between expected and output.
It SHOULD be exactly 1CM. On my printer, it came out at 9.88x10.00x10.11

A second cube is 2CM.

X and Y axis are on the side of the cube that corresponds to the axis being printed. (ie X on side to side, Y on back to front)

I also included FreeCad designs I used to make it.

To calibrate your x and y axis do the following:
(distance expected / distance printed) * current steps value = NEW steps per mm value.
get the steps per mm value with the command
M503
which returned
echo:Steps per unit:
echo: M92 X100.00 Y100.00 Z400.00 E280.00
...

So my case, 10/9.88 * 100.00 = 101.214574899
So To set the new value
M92 X101.214574899
