g31 will only run 2 times.  Is this a bug in the ess plugin??

inst = mc.mcGetInstance()

mc.mcCntlGcodeExecuteWait(inst,"G90G00 X-4.2 Y-.6") --position at beginning at pin setpoint

mc.mcCntlProbeFileOpen(inst, "C:\\mach4Hobby\\GcodeFiles\\KFCProbeValues.csv","%.4AXIS_ %.4AXIS_Y\n", true)

     mc.mcCntlGcodeExecuteWait(inst,"G31 Y-.65 F20.0")
     mc.mcCntlGcodeExecuteWait(inst,"G91G00 X-.1 Y.07")
     mc.mcCntlGcodeExecuteWait(inst,"G90")

     mc.mcCntlGcodeExecuteWait(inst,"G31 Y-.65 F20.0")
     mc.mcCntlGcodeExecuteWait(inst,"G91G00 X-.1 Y.07")
     mc.mcCntlGcodeExecuteWait(inst,"G90")

     mc.mcCntlGcodeExecuteWait(inst,"G31 Y-.65 F20.0")
     mc.mcCntlGcodeExecuteWait(inst,"G91G00 X-.1 Y.07")
     mc.mcCntlGcodeExecuteWait(inst,"G90")


mc.mcCntlProbeFileClose(inst) --close probe file

Working but not sure what I did different!
