I notice that some forum members here have taken to installing aftermarket scales like igauging linear DRO's on their Sherline milling machines, ostensibly because the opinion is that the Sherline DRO counts handwheel revs and the backlash in the screws is unaccounted for. However, in their marketing description of their DRO Sherline has the following to say;
"Backlash can be electronically eliminated by setting its measured value into the readout box for each axis. When handwheel rotation changes direction, the backlash value is electronically subtracted before the readout counts in the other direction."
If Sherline's DRO electronics can zero out the backlash then wouldn't it make sense to go with their DRO as opposed to going through the trouble to install aftermarket linear (magnetic) units? Or is there a cost or other advantage to doing this that I am not aware of?
