New PM-728V-T Mill

Servo , stepper brakes that I have encountered are either physical shaft brake mechanism's or Electrical braking using heat sinks . I am no expert on this subject matter . I suggest serching for servo brake. I believe DMM servos and several other's offer built in braking via controller/servo combination.
 
Think I'll cheap out on a brake option. Put a sign on the power off switch "Park the Head First" :)

I don't have a problem with the z axis falling. Although I do remove all bits and lock the head before putting it to bed. :)
 
mine might stay but it doesn't take much of a jar to get it to do a face plant if I forget to lock it.
 
Received email from PM that my CNC ballscrew conversion kit and 0-10V motor speed control module for the PM-728V-T have been shipped. Less than 30 pounds ship weight.

Shipping stalled for awhile, but it is finally moving. Should see it early next week.

Hopefully they have selected properly. It has a 5 year warranty if I remember correctly.
This may be another reason to consider a counterweight setup.
Here's a THK guide on ball screw selection.
