I have tried searching for information on the Abnormal Condition LED within the forum but can only find two posts, one of which is mine, and ther is nothing in the index of the Mach3 manual. I can see from using Screen4 that Abnormal Condition LED is triggered by OEM condition 166 but where in Mach3 is/are these codes embedded? I ask this as i am getting the Abnormal Condition LED after adding to the code of the Reference All Home button. I'm not changing that code just adding SendSerial("D44") to initiate the datum procedure of my ATC.
