Setting the X Beam for drawing
Clamp the upper X Beam above the material
To ensure the wheel units on the upper beam do not crease your drawing material, the upper beam will need to be raised to a fixed position around 10mm above your material.
How do I set the X beam height?
To set the X beam height, loosen the clamp on each end of the upper X beam.
Lift the X beam up so that the wheels are around 10mm from the material ensuring it is parallel. You may want to use a piece of material to set this more consistently.
To secure the beam, retighten the clamp handles.
