How bout this idea??

I am doing some serious CNC cramming trying to learn as
much as I can for my conversion , which I will be using steppers ,
only because I have them now. I only thought of this after......

If I get good feedback about this I might sell wht I have .....

I came up with this idea , using regular DC motors , not servomotors

mounting linear encoders right to all the axis's

would eliminate the need for Servo motors , would eliminate
the need for Zero lash ball screws ,would eliminate the need
for expensive servo motors , wouldn't have to compensate for any
backlash because it would be reading actual table movement .

And the benefit of the ACME screws friction to help hold
the table in position .

And you could tie in for DRO use ,or tie into an existing DRO
for CNC use if you already have one.

Good idea??? Any body have input??? .
Already in service??

Or is this totally crazy
