Connecting to a 3018-PRO
The first thing you should do is disconnect both sides of the electrical connection to the spindle motor. Then
remove the spindle motor from the motor mount. Do not operate the SainSmart 3018-PRO with both the laser
and the spindle motor connected!
Slide the laser head into the motor mount so that the corners are in the slots of the motor mount and the cooling
fan of the laser head pointing upwards. Position the laser head so that the lower edge of its heat sink is about
60mm above the work piece. At this distance, it is usually very easy to adjust the optimal focal point of the laser
at a later time. Tighten the clamping screw on the motor mount, do not over tighten, it just needs to be secure.
Plug both connection cables into the sockets of the laser control module as described before.
