Do you by chance have a 1-2-3 block? You may need to bump the z pot up a little if you are losing steps raising the bit.
Try zeroing the bit to the top of some material and then use the jog controls in Easel set to .5" to jog twice up and then twice down. Slide the material back under the bit and see if you are still at zero. then do it with 1" jog.
When I change the depth of the cut to .48 instead of .50 it cuts fine… But I want to be able to cut the tabs in the wood. Do you think it could be a calibration issue
