The print carriage enables the following modules to carry out their functions:
●
Printhead Assembly - to transverse across the stencil in the Y direction (print stroke - auto-
matically set from the board width parameter)
●
Screen Change Module - to perform a stencil load or stencil change
All positioning of the print carriage is referenced from the home position and calculated in the
machine software, taking into account:
●
Board Width
●
Front and Rear Print Limits
●
Front Rail Justification
●
Hop-Over Distance
●
Squeegee Pitch
The print carriage only homes during initialisation, which can be from power-up or exiting dia-
gnostics.
I/O Node Board 3, located inside the print carriage extrusion, has an onboard temperature and hu-
midity sensor. For information on I/O Node Board 3 refer to 9.4.4 "I/O Node 3 (Print Carriage I/
O)" [}123].
For information on the print carriage solenoids refer to the Pneumatics Chapter in Volume 2 of this
manual..
