PRINT CARRIAGE MODULE
OVERVIEW
Chapter Issue 5, Aug 14 Technical Reference Manual 8.3
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 - 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 stencil load or stencil 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 3 refer to
the Machine Control Chapter
For information on the print carriage solenoids refer to the Pneumatics Chapter
and the relevant module chapter.
