General Mach Discussion / Offset for multiple heads
« on: September 11, 2010, 01:16:34 AM »
Hi. I have searched this forum and couldn't find an answer to this question. So, I thought I would start a new topic. I have two CNC plasma tables with a plasma head and a marking punch. The marking punch on one table is 6 inches in the x direction, and 1 inch in the y direction away from the plasma torch tip. On the other table, the punch is 4 inches in the x and 2 inches in the y direction away from the torch tip. I use SheetCAM to generate the G-code for these two machines. Since I would like the Gcode to be used on both machines, I don't want to use the SheetCAM post processor to offset the tool for me (I would have to create twice as many Gcode files). What I would like to be able to do is have Mach3 offset somehow when each tool is selected. In other words, I would zero out each axis before I start a cut, and when the punch tool is selected by the Gcode, Mach3 would offset the coordinates so that the punch would be striking in the correct location. Does anyone know what the best method to do this would be?
Thanks,
Frank
