Intro
This is a quick update in the Start a Movement Design Challenge to demonstrate the assembled thread tapping system with both stepper motors running.
The 6-32 tap that is in the chuck requires the lead screw to provide 1 inch of forward travel, for every 32 rotations of the tap bit.

Discussion
The hardware for the thread tapping machine is now complete and working very well. The Analog Devices Trinamic stepper motor control system provides micro stepping control which allows the linear actuator to be precisely synchronized to the rotary actuator so that any tap can be accommodated. I am still at a loss as to how to get the system to use more than 30 mA, but the planetary gearbox provides so much torque multiplication, not much current is needed.
