I'm assuming that you are referring to the custom tool change macro, mfunc6.mac, correct? It actually looks like the custom tool change macro was moving at a fixed feedrate of 100mm/min when the system is in metric mode or 100in/min when the system is in imperial mode. Please copy the attached file into the c:\cncm directory and see if that works for you. That will jog based on the value of parameter 14.

Hmm, something weird is going on. I loaded the macro you supplied. Same issue. As a test I divided param 14 by 10 so it became 15. Then it did the fast probe at 152 mm/min. Acceptable, I was able to run the macro fully and touch off but the Z axis setting wasn't anywhere close (at least 200mm off) I divided #71 by 10, closer but still way off. I then tried converting #71 to inches which got it really close but it was still roughly 5mm off. I think something is up with how the macro handles mm vs inches.

Installed a stationary tool height probe and switched to Clint's m6 macro. Works great. This saves a ton of time on tool changes within a job.

Thank you!

After using the Original Macro for a while I found there were times when I only needed the movable plate. I modified the Macro to include this functionality.

One weird thing that I have noticed: Whenever I power cycle the Acorn the M6 macro doesn't work properly (the Z-axis moves up instead of moving down looking for the touch plate) until I either activate the TT1 or touch the moveable touch plate to the bit.

Is this normal or is there something wonky with my setup??

Thanks!

Was the machine homed after the reboot?

Yes

Folks,

I've come across a curious issue. I am currently using the original tool touch off code "mfunc6JogToToolTouchOff-tt1.mac". It works great, and many thanks to the author. But this macro interprets parameter 71 differently than CNC12. For the macro, you enter the thickness of the probe as a positive number, and the macro subtracts this off the measurement to get to the part/reference. For CNC12, you have to enter the negative value for parameter 71 if you go through the part setup menu.

Is there some pilot error on my part here, or is there a misinterpretation of the two zeroing methods?

As I remember it, and I am not reviewing the code now, the action is to set the Current Z position as the value of parm 71. In my reasoning, the number would have to be positive as the touchoff device would be above the surface that you wish to reference the Z to.

Are you sure something else is not amiss?

I just performed the below option:

When I go into setup I do not get pop up dialog boxes that give me options lie in the videos. I just get the same original "set part position" screen and when I select "auto" the z axis drives Negitive towards the touch plate. Once it contacts the plate it backs off slowly and then moves back down to touch it again and only then does the relay click and the Z axis is set to the dimention I inputed. In my case it is .98.


Three questions: How come I am not seeing the Marco display? Why when I select "save" does it reset to 0.000? And Why does it not reflect a positive value since it is infact 1 inch above the work surface?

Thank you
