graduated vial.
Measuring in Y direction

Adjust the horizontal levels of the machine (X/Y direction) by rotating the leveling
bolt with a 46mm spanner.
Set a 46mm spanner on the lower
nut of the leveling bolt .
Note
One rotation of the leveling bolt raises/lowers the bolt by 2mm, 1/6 rotation (60 degrees, angle of
one hex side) by about 0.3mm and 90 degrees by 0.5mm.
To adjust the machine level, rather than rotating one leveling bolt at a time, rotating two bolts in
conjunction is easier and more efficient for adjusting X or Y direction levels respectively.
Check the bubble
position.
Horizontal levels (X and Y)
1 Machine is horizontal (OK).
2 Machine is somehow slanted but at an acceptable level.
