M6 Routine Always Moves to Z0

Post by smayes »

I'm in the process of getting my new Acorn conversion setup and working the way I want it to and I'm having a hard time with the tool touch-off routine.

I downloaded the mfunc6JogToToolTouchOff-tt1.mac made by Scott Pratt and it worked fine, but I didn't want it going to the home position every time I want to re-zero Z, so I removed the G28 command before the tool change prompt. My problem is it still drops Z down to 0 as soon as I hit cycle start to run M6 and I can't figure out why. Any help is greatly appreciated because I'm ready to start testing/tuning this machine, but the tool change is a big fly in the ointment right now.

The mfunc6.mac that's currently in my cncm folder is attached.

Thanks

Sam

hi,
did you try to use the menus that are built into CNC12 first before trying a custom macro..that one is pretty old as well..
there is better newer stuff here...

Hi Sam,
What post processor are you using? What CAD/CAM software are you using? I have a custom macro I created from various M6''s posted on the forum that is specific to my machine and workflow and my Vectric PP was causing a similar issue. It wasn't dropping to zero but to the tool height clearance set in my CAD/CAM software. I didn't want Z to drop until it was over the area where it was to begin cutting for fear of hitting anything I used to hold down material. I had to edit both my PP's to get it to stop this move. More than likely it's not your M6 but your post processor causing the Z move and you'll have to edit your own PP in your CAD/CAM software to stop this move.
