An easy solution that should apply to most machines that use work coordinates is how I commonly approach this. I reserve two sub programs, one for a safety sub and another for a tool return sub. Examples as follows:(careful, codes currently for yasnac) M98P1 is forced at program start (tmp.) and contains defaults i.e.. SEE BELOW. (great for program restart, reset with tool anywhere and it first goes home) M98P2 is forced at tool change (tmp.) and contains cancels for canned cycles etc. but most importantly will have a G53 (temporary shift) for exactly what you speak of. This way you edit one file and get global tool clearance. % O0001(SAFETY SUB) G80 G91G28Z0 (Z home) G28Y0M9 (Y home if you want) G20G17G49G80G52G40G90G64 (defaults) G90G0 M59 M1 M99 %   % O0002(END TOOL SEQ SUB) G90G0G80M9 G0Z1.0 (INITIAL CLEARANCE) G49M5 G91G28Z0 (Z TO HOME) /G53 Y.1 X-15. (TABLE POSITION FROM HOME FOR TOOL CHANGE) G90G0 M99 %     -----Original Message----- From: Andy Beardmore [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 07, 2003 11:15 AM To: '[EMAIL PROTECTED]'; mfg-smartcam Subject: RE: [mfg-smartcam] Indexing Clearance This will cancel tool length offsets on some controls. You must be careful with this. -----Original Message----- From: Jeff Brower [mailto:[EMAIL PROTECTED]] Sent: 07 January 2003 15:17 To: mfg-smartcam Subject: RE: [mfg-smartcam] Indexing Clearance Our method of clearing an index is to rapid X and Z to home positions before the index. This will clear everything we've done so far, the machine moves so quickly that it's only a few seconds of time. -----Original Message----- From: DrFrye [mailto:[EMAIL PROTECTED]] Sent: Monday, January 06, 2003 4:09 PM To: mfg-smartcam Subject: [mfg-smartcam] Indexing Clearance How do you handle coding a clear point while indexing the pallet on a horizontal machine?  I suppose this would apply to a vertical with an indexer also.  Say I have the clear plane set to 1.0" which is my usuall setting.  When indexing, I may need 8 to 10 inches for clearance.  Do I modify the element's clear plane, hard code a clearance value in the .tmp file, create a clear point and just hit it before I change workplanes?  Is there something in the .smf file to handle this?  I have been just fixing the code in the text editor...I prefer edit free code.   thanks, Dale
