So you just need to have the polarity of the X axis (and maybe the spindle direction) switch when the rear tool is selected? Thinking aloud ... (from my http://www.wallacecompany.com/cnc_lathe/HNC/emc2/configs/hnc_io-3a.hal ) ... # create signals for tool loading loopback linkpp iocontrol.0.tool-prepare iocontrol.0.tool-prepared linkpp iocontrol.0.tool-change turret.0.position-change linkpp turret.0.position-changed iocontrol.0.tool-changed ... Instead of turret.0.position-change, you could have check-for-rear-tool.0.check and /.checked, .rear-tool. You would have to stick to a range of tool numbers that would be considered rear tools. Then in the spindle section, use check-for-rear-tool.0.check.rear-tool to change the sense of the spindle direction. ("newsig" is old, should update to use "net" properly) ... ### SPINDLE ### # connect spindle fwd/rev to I/O controller newsig SpindleFwd bit newsig SpindleRev bit newsig SpindleDACen bit (insert HAL component to switch spindle sense) net SpindleFwd motion.spindle-forward linksp SpindleFwd parport.0.pin-01-out linksp SpindleFwd or2.0.in0 linksp SpindleRev motion.spindle-reverse linksp SpindleRev parport.0.pin-02-out linksp SpindleRev or2.0.in1 ... I haven't thought much about this, but it might work.
