* NOTE: P/N 8780 includes the driver box. P/N 8781 does not include the driver box.
CAUTION—Protect your motors, cables, and driver board!
• Never connect or disconnect the optical encoder grounding cable or
the stepper motor cables with the Controller/Drive box power on.
• Do not unplug stepper motors using the rectangular white plug that
goes into the motor. Disconnect only at the cable plug.
• Do not pull on cable wires to disconnect plug—grip at connector.
• Turn handwheels slowly (1 rev/sec) with driver power OFF when
manually positioning. For longer travels use Jog Mode.
Assembling Your System
Mill or Lathe: Unpack and assemble your machine according
to the instructions included in the Sherline Assembly and
Instruction Guide packed with the your new machine.
Unpack the P/N 8760 driver box and the P/N 8781 Sherline/
MASSO controller box.
Set the driver box on your table first, then set the controller
box on top of the driver box.

Shown here is what comes with the Sherline/MASSO Controller for our mill package.
A lathe package will be similar except that it will have two limit switches instead
of three, and different mounting hardware.
After you have read all the instructions and watched all the how-to videos, please feel
free to send us any feedback so we can improve our MASSO controller documentation.
Email marketing@sherline.com with your suggestions.
FIGURE 2—Front view of the controller box and the driver box.
Connect the white X, Y, and Z stepper motor cables leading
from the back of the driver box to each of the stepper motor
connectors. The axis that the cables will control are laser
engraved on the driver box (see Figure 3). A fourth cable is
unused unless you have purchased an optional CNC rotary
table, which can be connected here as a 4th (A) axis.

  • Page 5 Now push the cable support into place. Once the cable support is in place, tighten the two 10-32 screws in order to clamp the cable support between the motor mount and the headstock. At this point just tighten the top screw all the way, and leave the bottom screw alone.
  • Page 6 When your monitor comes on, you will see the control page Make sure that the spade connector is straight up and down below. The yellow Home icon will be flashing. The red so it sits in the middle of the motor bracket. Also be sure that E-Stop icon will be flashing, and the password box will be on.
  • Page 7 Now enter the password [ SP ] into the password box. The [SP] must be ALL CAPS. FIGURE 29 At this point you would normally home out your machine. Instead of homing the machine, we are going to go to the Setup page so you can see the input signals from your encoder and your limit switches.
  • Page 8 headstocks. The parts and the procedures are the same Mounting the Optical Encoder for our 3C headstock with the exception of the encoder spacer block. For the standard headstock we use spacer P/N 87816 and mounting screws P/N 40720 (10-32 x 1-1/2" The power switch on the speed control must be in the SHCS).
  • Page 9 You may need to drill and tap the 10-32 holes on your headstock to mount the optical encoder. If this is the case, please go to the page 20 of this document for the Optical Encoder Mounting Template Instructions. FIGURE 40—Encoder Gap Gauge P/N 87813.

Now we are going to mount the encoder cover. FIGURE 42—With the gap gauge in place, apply pressure on First a special note: The primary reason for the cover is top of the encoder.
  • Page 11 If you turn the spindle pulley by hand starting with the index point under the encoder, the signals will come into the setup page. See the signal sequence below. FIGURE 50—Then Signal-B will change to Low. The inputs will follow this sequence from position 1 through position 4.
  • Page 12 Tighten the mounting screw snug. Then readjust the cover so there is still a gap between the cove and the pulley. FIGURE 53—Placement of encoder cover P/N 87812. FIGURE 55—Encoder cover mounting screw P/N 87811 5-40 x 3/8" Phillips, button-head machine screw. There must be a gap between the front edge of the cover and the tach/encoder sticker so it doesn’t rub on the sticker.
