Does the new Centroid EX control system come with a brake for the Z axis? I know from experience that Servos have much less frictional holding force when not powered, and may be OK with a 4 hp spindle, but with the 8hp spindle, I would imagine the Z will drop when powered down without the use of a brake for the Z axis motor.
Yes all EX controls require a brake. We send a simple retrofit kit when you order one.
Going forward all of our Z axes will have an electric brake regardless of whether or not you get steppers or servos
My 4HP CNC Depot stays in place… But, I can easily move it down if the servo is disabled. I’m using ClearPATH servo’s on everything.
Yeah our drag brake has JUST enough resistance to hold the 4hp… but just. That’s why we’re switching to the electric brake.
