Before the 24ft bed Biesse came along I ran on a 442 Heian twin head, twin 63"x63" tables with a 2" seperation, I use a m40 to lock the tables in the program. Because the heads are fixed in the gantry and the tables move in y I have only 12.5" at the back of the machine where the stringer will not hit the beam uprights, if I ran the stringer in the front it would hit the saftey gates on either side of the table. I usually set the 0 of my program at my pinstops bottom lh side of the tables, so in this case I offset my part X-65" Y63 from my right hand table as I will machine every thing with head #1 (head seperation is 800mm) I make my tool paths in Mastercam, create the first program, save it take my second DXF and create the program. I cut and paste the programs together inserting an optional stop and releasing the vacumn so I can move the part, turn the vacumn back on, then restart the program to finish. If u r wondering, I have sub programs set up in the controller I made to put pins up/down, bring the machine back to home, turn vacumn on/off, they r the p#s. Here is an example of code, (I cut all the crap out) and a couple of DXF's
Hope this helps u out.
Cheers
