Mach 4. Ess SmoothStepper. Router/Mill. New setup with an ATC I am going to use for manual tool change for now. Seems to be a good idea any reason why not? If I set my probe up in a holder and leave it there as #1 master tool. My very first op is almost always to probe the top and WCS with the remainder of my tools following. Is there any reason why I wouldnt?

The only issue I might see in the future is when I flip a part and set the WCS on the underneath the issue being my probe might not be long enough for the higher parts I manufacture. In this case I have used a long 8mm endmill to get my Z.

Anyways. If someone is keen to give me feedback would be appreciated.
