Does anyone know what this means in the manual?

I've just updated the firmware of my mk2 to 3.10 and done a Calibrate X,Y,Z which is now reporting the following error:

“XYZ calibration compromised. Front calibration points not reachable.”

Section 6.5.3.1 of the manual ( http://www.prusa3d.com/downloads/manual/prusa3d_manual_mk2_en.pdf?5#_ga=1.95066516.941349357.1475273077 ) reports the following (page 19):

If the Calibrate XYZ gives “XYZ calibration compromised. Front calibration points not
​ reachable.” error, you don’t necessarily need to adjust the M10 nuts and position of the axis
in the frame, but you can adjust the belt holder position. New version of the Y-belt-holder
with a slot (shipped from August 8, 2016) allows to make a 1 mm adjustment to both the
front and the back. Loosen the Y belt holder screws, push the belt holder part towards the Y
motor and retighten the screws.

I don't like the thought of changing the M10 nuts but I will if I need to, because every time i've done that in the past i've had days of frustration and fiddling.

What does the bottom part actually mean about the belt holder? The belt holder only has two screw holes and they attach to the bed directly. How can it be adjusted by 1mm either way?

I've asked support via the webchat and they couldn't even explain it to me and told me to adjust the M10 nuts.

Stephen, apparently there are 2 variants of the Y belt holder part:

1) with only 2 M3 screw holes
2) the one the manual probably refers to, which has 2 slotted holes allowing for a slight position adjustment

If you have version 1 you're probably stuck with adjusting the M10 nuts...

Thanks. Weird, I didn't get my printer until the end of October and it does not have slots, only holes.
