CONNECTION
Do not connect a LGX®PRO stepper motor to a printer’s cable without checking the wires and pins of the connection cable.
Not all printers are ready for a direct connection with the LGX®PRO. Some use stepper drivers with no protection and this may damage them.
Before connecting a LGX®PRO Pro to any 3D printer check if the
connector pins are wired as shown below:
After start of service, if the LGX®PRO is turning in the wrong direction,
swap the top (or bottom) pair of wires to make a correction:

ADDITIONAL MOUNTING POINTS
Use the supplied studs to replace the 4 screws of the stepper motor
and use them as additional mounting points.
Be aware the stepper motor threads are made of Aluminum, and they
are delicate.
Don’t use too much Torque to tighten the studs. Preferably use nger
force only.
You can nd these studs on the accessories bag in your LGX®PRO
package.
They have an M3 thread with 4 mm depth.
