DRO - Tool Location

Is there a way to see what the tool location is, like a dro display?
If I need to move the spindle in order to change a bit (because there isn’t enough room even with the z as high as it will go), I’d like to be able to move it back to the correct location.

Are you referring to a bit change for material that has not been moved on the machine?
Work zero is maintained until it is told to change it.
If using Easel, just use Easel to jog the machine to a location that will accommodate the bit change. Then select carve and it will ask if you want to use the last XY position. just select yes then set your Z height for the new bit and you are good.
