Having no practical experience with a CNC yet this is only a guess, but could you return to zero before switching endmills? Or would you end up still having to estimate Z position.<br><br><div class="gmail_quote"><div><div>

<div>Problem is I wont know where zero is for the work in progress. It's easy to estimate zero at the start and it works okay for cutting. But to continue work, an estimate wont do. It has to match. </div>
