G-Code, CAD, and CAM discussions / WORK OFFSETS
« on: March 30, 2019, 06:44:11 PM »
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

G-Code, CAD, and CAM discussions / Homing on the fly

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

General Mach Discussion / Manual Referencing
« on: February 10, 2016, 07:23:48 PM »
When my machine is cold in the morning I have to reset most the home limit switch positions and then latter in the day put them back when it warms up.  I have XYZ fixtures to position a dial indicator to see this error.

My question is...  I can't find the command or a procedure to set the axis to home/zero manually using the error amount I know from the indicator.  I can put the axis where they should be but I can't make it reset (call it home or machine zero) to this position??

Or......  I have X when set with the limit switch, it is .006 off, can I make the machine reference .006 from this position, Thanks

General Mach Discussion / Home Macro

If you think you have your motors tuned for the max speed and are losing none or few steps, why would you not speed them up for long runs and "re-home" 1 or more times (while running) with code or macros?  Seems too easy, whats the downside?  Any tested macros available? Thanks Edward
