OVERVIEW The print carriage enables the following modules to carry out their functions: • Printhead Assembly - to transverse across the screen in the Y direction (print stroke - automatically set from the board width parameter) • Paste Dispense Module - to supply paste at the required position of the print stroke • Screen Change Module - to perform a screen load or screen change NOTE Two types of the printhead assembly are available for fitment to the print carriage: a Squeegee b ProFlow Information on both types are detailed in the relevant module chapter of this manual 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 The print carriage only homes during initialisation, which can be from power-up or exiting diagnostics I/O Node Board 3, located inside the print carriage extrusion, has an onboard temperature and humidity sensor For information on I/O Node Board refer to the Machine Control Chapter For information on the print carriage solenoids refer to the Pneumatics Chapter and the relevant module chapter Chapter
