You can use the signal "machine-is-enabled" to release the servo brake. But normally the brake is connected to the servo drive, when the drive is enabled it releases the brake.Over time i have picked up a few servo motors. All in hopes of repairing a mill I have. I have noticed some have brakes and some don't. Does the Linux CNC support a brake on the servo? Is it something needed?
Thanks,
Jeff

So the brakes only engage when the machine is "Parked" and or turned off? So if I am making a 4 inch cut on the X axis. The Y and Z are held by the motor holding position and not by engaging the brake?

This is the typical situation, so yes.
