Genmitsu GS-775MR CNC Motor

Experience a quick and easy upgrade for your Genmitsu Desktop CNC. The GS-775M motor fits all Genmitsu 3018 series CNC router machine: 3018/3018-PRO/3018-MX3/3018-PROVer. Easy Installation for a quick swap of the OEM Spindle. This motor with higher speed for you to do more engraving work efficiently.

Note
Wiring: Red lead connects to the positive pole, and black lead connects to the negative pole. If the wiring is reversed, the motor will rotate in the opposite direction.
Overload: Keep the motor is within the specified load range as far as possible. Don't block the motor or keep it run in a stall status for a long time. Otherwise, the motor will burn out.

Specifications

Rated Voltage: DC 24V

High Speed

The motor speed is 24V 20000 RPM, which is 10000 RPM higher than the original CNC spindle motor. You can do much more engraving and drilling work with this great motor.

Application

The motor is suitable for desktop drilling machines, desktop milling machines, CNC router machines, cotton candy machines, small lathes, precision machine battery vehicles, toy cars, etc.

Note: The offline controller of 3018-PRO can't work with this 20k spindle.

The way to get the new GS-775M spindle motor up to speed is to increment its runup using a sequence of GCODE commands. Those are shown here:

(Applies to new SainSmart Genmitsu GS-775M Spindle Motor)

(Spindle Speed 10000 RPM X 2; Set 10000 value for max spindle speed in Candle Settings)

(Ramp up spindle speed GCODE to prevent power supply overload)

M03 S1000

G4 P0.5

M03 S2000

G4 P0.5

M03 S5000

G4 P0.5

M03 S10000

(Spindle is now running at full speed)

This method is known to prevent overload of the power supply.

An alternative is to replace the stock power supply with one having greater current capacity (24V 8-10A), but that may burn out the controller with an abrupt 100% speed command.

However, a larger power supply should provide more cutting power from the GS-775M spindle, but the power-up sequence shown above is still recommended.
