Hi all,
I'm new to this CNC building and just now starting my own machine.
Is it a typo where you said they used 16 ft lbs servos? I thought
this figures out to 3072 oz-in and the ones you purchased were rated
at 360 oz-in or 22.5 lbs-in. There seems to a mix up in ft-lbs and in-
lbs. Then again I am new to this
