General Mach Discussion / Re: What is a "MODERATOR"?

The original idea was to have moderators from all time zones so we had 24 hour coverage.  As we have just about stopped the spammers that used to drive us all mad with there constant bombardment we probably don't need as many, but what the hell it costs nothing to have plenty.

No, Mach3 has to have a file loaded into memory, Mach3 has no limit on file size.

G31 z-10 f25. will move the z axis minus 10mm unless it senses the probe touch something. At the touch point it stops and you can take a reading and do what ever you want with the data by calling a M code.

When you are playing with macro language commands most g-code systems are different, # is not part of the standard, Mach3 follows the Fanuc standard.

The only way round it is search and replace.

The probe can be mounted anywhere on the machine, you will have to know where it is in relation to the spindle so you know how much to offset the x,y positions by.

You can write your own commands into the g-code to take measurements at known points to do this you can use the G31 command.

Have you set use radius for feed in toolpath config?

Have you set the radius of the part in the setting screen?

If you set your DRO to 222 and run this program the DRO counts down to zero, you have to use a small delay to give mach time to update the DRO's.

So do I take it you are setting a new zero point in mid program run?

Most probing routines take 2 or 3 hits per reading, first is a fast traverse to find the object, it then backs off say 1mm (.040") and then slow feeds to find position. For very fine detail it backs off again .25mm (.010") and then creeps to find the position. At this point the final reading is taken. The accuracy is then down to the trigger action of the probe.
