Using your 775 Spindle Motor

One of the key attractions of this upgraded spindle is the ability to turn at 20,000 RPM. What you may find the first time you try to utilize the spindle at it's maximum speed is that it will not turn properly.

Please do not be alarmed. What is happening is that the current being drawn when the spindle tries to go from 0 to 20,000 RPM is more than the 5A power supply that came with your CNC can provide for that moment of peak power draw.

That being said, if you ease the spindle into the maximum RPM, everything works without issue. How we suggest you do this is by replacing your spindle speed command with a few extra lines of code which brings your spindle up to full speed over the course of a second. In order for this code below to work, make sure to set $30=10000 in your console. This sets the maximum spindle speed in your firmware.

So S10000 M3 is replaced with:

S4000

M3

G4 P.25

S6000

M3

G4 P.25

S8000

M3

G4 P.25

S10000

M3

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.
