So a few month ago I had to move my BigBox Titan Dual and ever since have had issues with having a consistently level bed and just getting Z height to stay the same(which it won't do). In my hunting around for a solution found that the IR sensor is only suppose to flash 2 times at startup...mine flashes 4 times. Can someone give me some instruction on how to calibrate this sensor or how to test if it is even good, because I'm really questioning its viability right now. But I'm open to the fact it could just be miss configured. Thanks!
