Re: [CAD_CAM_EDM_DRO] Re: Gecko Faults

16 oz to the pound. 16 x 16 is 256 oz-in. Should be ample torque for that size mill with some reduction. Servos like lots of RPM.

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
