There are two methods to coplane the chase:
A B
●
A - Manual
●
B - Auto (Optional)
Manual coplanarity is fitted as standard on the machine, where accurate measurements are taken
by an engineer between the chase and the top of the conveyors. The chase is adjusted in the X
and Y by the engineer to achieve parallelism.
NOTE
Manual coplanarity is achievedby using a calibration kit available from your local CSG office. The
kit comes with full instructionson the procedure.
Auto coplanarity is an option on the machine, where accurate measurements are taken (by two
lasers) between the stencil and the top of the transport conveyors. The chase is automatically ad-
justed in the X and Y by two stepper motors to achieve parallelism.

Two laser sensors mounted on the print carriage are used to take accurate measurements allowing
the software to accurately parallel the stencil to the transport conveyors. With the stencil removed,
the laser sensors measure the distance to the top of the rear centre section of the conveyors. The
print carriage moves forward and measurements are taken to the top of the front centre section.
With the stencil fitted, the laser sensors measure the same four positions. The software uses this
information to calculate the error and level the stencil to the top of the conveyors and drives the co-
planarity motors to achieve this.
