Starting A Production Run

I have commented before about how the Sherline CNC mill is not powerful enough to do large scale production work, but it still amazes me that I can afford a tool like this! 

I did have an odd failure last night.  The Y axis was suddenly not going where it should.  The coupler that locks the stepper motor to leadscrew had disengaged.  This was easily fixed, but one more thing to check before starting the mill.
