Re: [CAD_CAM_EDM_DRO] DRO question (DRO kit verses an off the shelf product)

If your scale for Z axis is on the compound and you leave your compound at 30
degrees as we used to for threading, the sin of 30 is .5 so that you will read as
diameter rather than radius if you advance the compound. You must remember to
compensate your X readout "0" each time you extend the compound.
