Wanting to add a DRO to my mill/drill (RF30 clone) and am considering
theSchumatech DIY DRO. My question is do you have to be concerned about
backlash when using a DRO or does the scale compensate for it. Seems as
though the DRO gives actual position and Backlash is no longer a problem?

Fo those of you who have built this DRO before, is this a project someone
with little electronics experience can do?

Thanks all



Maybe I didn't understand what you were asking about backlash, but I
still think that for side milling you should approach the reading you
want from a direction the mill will "push against" when you start
cutting. To do otherwise invites dimensional disaster, particularly if
you can't or don't lock the slide before starting the pass.
