Is there an easy way to re-zero in the middle of a program?

[EricAZ]

Is there an easy way in CNC12 to reset the zero for the Z-axis when changing a tool? I tried cancelling the job, resetting zero for a new tool, and resuming but it did not behave as I expected. In this particular case I do not have enough holders to set everything up in the tool library ahead-of-time. I have looked through the manual and other posts but am not finding anything. Thanks

Easy solution is to post one file per tool.

There are numerous examples of mid file tool setting for manual change spindles in the Centroid tool change example files. Also a number of users have posted their tool change macros for MTC spindles

I would use a Mfunc6 macro, which gets called instead of your normal M6 tool change. Put a M00 code in that macro which stops and allows you to jog your axis and set Z zero again. So every time M6 gets called, you end up calling M00 to pause and allow jogging, and then you can set your new Z-zero. You are going to want to add code to stop spindle, coolant and do any other chores that need doing at tool change time.

Thanks for the responses. I used the "separate posts" idea to get me through the job I was running and will dig into macros more. I'm just getting started with CNC12 and still have a lot to learn. I'll definitely check out Swissi's ProbeApp.

Gary mentioned the "Centroid tool change example files". I'm guessing that he was referring to the examples in the back of the book "Introduction to Centroid Acorn CNC12 Macros". If there is another source please let me know. They would be great info as I learn more about macros.

As Nigelo mentioned above, the ProbeApp is perfect for what you want to do. Just add a M58 command into your tool change macro mfunc6.mac and the ProbeApp will come up at every tool change and will allow you to reset WCS and then let the job continue. If no WCS reset is necessary, you just exit the ProbeApp and the job will continue.

Check out this POST or the ProbeApp User Guide for more details on the ProbeApp.
