TURNING OFF WORK OFFSET?

Recommended Posts

We have an older lathe that does not have work offsets and does not like G54 to be output... Anyway to turn it off in the control def or post. Using an MPLMaster 2019? I tried changing the plane to 0 instead of -1 but apparently not that easy. Any help is appreciated, lathe is not my thing and as always Thanks for the help

In the "Generic Fanuc Lathe Posts" from CNC Software, this is tied in at the "Operation Level" to 'Miscellaneous Integer 1'.

MPLMaster, does away with the control at the "OP" level (smart of them, because nobody ever switches "on the fly" for output type).

In MPLMaster, look for the following variable:

home_type    : 2     #Work coordinate system: (home_type)
#       -1 = Reference return / Tool offset positioning.
#       0 = G50 with the X and Z home positions.
#       1 = X and Z home positions.
#       2 = WCS of G54, G55.... based on Mastercam settings.

Set it to either "-1", "0", or "1", depending on the type of Tool Change Reference Position Moves, you want to output...

Colin, Thank you sir. Our new lathe programmer was going nuts trying to figure out why all his offsets on this one machine wouldn't hold. Then when he figured out it was the g54 throwing it off he was like OK ill just manually edit the code. Ill set him up a Control def and post specific for this machine tomorrow he will be pumped.

Typically on a "no work offset" type machine, I use 'home_type = 1'. With that setting, you need to enter the Home Position for each Operation. This will output initial and final XZ values, using these positions for the safe tool change position.

Copy That Buddy!
