11. Select Squeegees.
12. Select Calibrate Heights.
13. The following machine sequence is carried out:
a. The rails are checked for the presence of a board.
b. The rising table is driven to print height.
c. The board clamps are closed.
d. The print carriage drives the front squeegee over the front rail.
e. The front and rear squeegees are driven down by the stepper motor to
dwell height.
14. Select Calibrate Front Squeegee.
15. The front squeegee is driven down to the current reference height position.
16. Select Jog.
17. Open the front printhead cover.
18. Using a 0.1mm shim placed between the front rail and the front squeegee,
check that the shim moves with a small amount of friction.

CHAPTER 10 PROACTIV
OVERVIEW
Introduction ProActiv™ is an active squeegee module. The ProActiv mount assembly (which
is similar to the standard squeegee mount and shares common functionality and
construction), houses the active squeegees. The difference is apparent when
using ProActiv during a print stroke, the squeegee blade is activated, this
provides additional forces in the print direction; it modifies the rheology of the
solder paste increasing its fluidity.
