There are 3 digits on the digital counter. They correspond to 1/100ths of a millimeter. It is
appropriate however to ignore the right hand column and adjust in 10ths of a millimetre.
The left hand digit represents millimetres.
Because there is some backlash in the adjusting screw, it is important to always make the
final setting winding in a clockwise direction. Thus for example to close the gap on a join,
it is necessary to wind the digital counter past the desired target number by approximately
0.5mm so that the final adjustment clockwise takes up the backlash in the screw.
NOTE: It is recommended to make a record of the setting difference between a butt join
on a straight edge and each of the appropriate radii.
For example, if the setting for a straight edge is 100 (1.0mm) and the setting for a 650mm
radius join is 5.0mm, then this difference should be recorded. Thus if for any reason the
digital counter needs calibration, it is then a simple matter to re-calculate the settings for
each radius.
NOTE.
It is essential for reliable butt joins to align the panel in such a way that the C Axis
angle is /-5 degrees of one of either the X or Y axis when measuring for the
cut. (IE. the axis should be on one of 0, 90,180,270 etc at the time of the cut).
This is because the axis drive is used to control the speed the head is travelling
when measuring for the butt join. This can only be achieved if the C axis is parallel
to either the x or Y axes.
Some variation of the joints may occur if this process is not followed.
Thus for example, when performing butt joins on curved edges such as round
shapes or those where it is desired to have the butt join on a curve, the panel
should be set up so that when the rollers align against the panel at the beginning of
the cycle, they coincide with 0, 90,180,270 etc degrees of C axis rotation.
