The GlobalMAX can go through the motions of making a part
GlobalMAX can go through a "dry run" of a part, and go through all the motions of making the part without any water or abrasive. Right-click on the Start button to bring up a menu of choices.
Right-click on the Start button to bring up this menu
A dry run is useful to check that the machining head will not strike any fixturing, or run into the material when it makes the part. When working with uneven material, be sure to move the nozzle to the appropriate stand-off distance to see if the nozzle strikes the material.
The following options appear on this menu:
Start/Continue
This starts or continues making the part with full water pressure and abrasive. The GlobalMAX will operate in its normal mode.
Dry run at full (1/2, 1/4, 1/8) rapid traverse speed
This causes the machining nozzle to go through the motions of making the part, but with no water or abrasive. Choose how quickly it moves as a fraction of the rapid traverse speed.
Always pause the GlobalMAX before adjusting your fixturing. The machining head is heavy and can crush body parts against fixtures.
If machining is paused to adjust material or fixtures, right-click the button and choose the dry run speed again. Just click , and the GlobalMAX will begin operation using full water pressure and abrasive. The warning shown in the following figure will appear if is clicked after doing a dry run.
If you click after pausing during a dry run, you will see this warning:
Dry run in reverse at full speed
Use the option to "backup" along the tool path. This is useful when a fixture has been adjusted to check that part of the tool path will still clear the fixture.
Test nozzle
This brings up the Test Pump and Nozzle dialog, where you can test the pump and abrasive flow.
