I HAVE 2 STRINGS OF WORKING G CODE AND WOULD LIKE TO RUN THEM ONE AFTER ANOTHER AS ONE JOB. EACH USES A DIFFERENT OFFSET, ONE G54 ONE G58. WHATS THE BEST WAY TO DO THIS. I'M USING CODE FROM MESHCAM ON MACH3, THANKS

What few lines of code will return the machine to the home limit switches, stop on those limit switch and set the machine zero to the new positions? And then continue on with additional lines of code, hands off? Thanks All Edward

I could tell it was beyond it's capabilities from day one. If I replaced It, I probably would use a profile copier with a pattern instead of cnc. The dreaded analog.

Its a large wood carving that gets 10/20 thou fladder sanded off after carving. Where I need some help is with the alignment, or parting lines between successive runs.  Even these are heavily sanded. What I hope to gain is just some reduced sanding. The machine is very sloppy by metalworking standards but fair for woodworking tolerances. If I could I'd re-home every 15 min. I have been making the same product in the same quantities for 8 years.

G28.1 ?

Thanks, The machine is fair to poor but cannot, at this time, be upgraded or replaced. I'm afraid I have to work with the equipment I have, rather than the equipment I wish I had. Edward

I have a 30 minute plus program and need to re-home my axis about mid point, hands off, using code. I miss enough steps so that the end of the cut is out of position with the beginning. If I slow down for accuracy the time doubles.  I need to make about 250 so the time is important.  3 D Carving, using Mach 3 & MeshCam.  Thanks for the help, Edward

I have sharp marks at home but try to turn off the machine at home each night and then reference all. Then I move to a dedicated G position that is fitted with fixtures to accept a metal block with an indicator attached to read the blocks. When there I can read and note the error, go to home, nudge as needed and hit reference.  When I go back to my dedicated G all are dead on. I keep checking this position threw out the day. If I crash I set to my home marks by eye (I only need to get close enough to prevent misreading the indicator by 1/10 inch.

Eventually I want to place the measure point mid axis (all three) to halve the error and use the home position offsets in the Mach3 limits menu to eliminate  the go home step and the note the error step. Then I could just go to my G position and hit reference. Note: UNTESTED

Worked Great, Spent the day working within .002 instead of .005+ (multiple large 2 sided 3d carvings with parting lines). I move to my measure location, noted the error with a dial indicator, moved to home, nudged the axis and hit ref all.

For now I'll just leave the home switches disabled and manual home at startup, then reference as above.  I thought my machine was sloppy or very temperature sensitive, but it was just flaky proximity sensors. How close can you get with a good 12mm barrel sensor? The drawback I see is not being to do a G28.1 within the G code to pick up lost steps (30,000 line code)  Thanks again Edward
