So has anyone noticed a problem with the IR sensor when they use glue stick on their bed? Because I am definitely having a problem. If I put glue stick on the bed, even a thin coat, the IR sensor trips well before it should. So, every time I enter a G1 Z0 command (after homing), the bed raises like it should, but not as far as it should; adding over 1.5mm to my z-offset. This is annoying because I'm printing NylonX right now and it will not stick to hairspray; only glue stick. I have a new sensor on the way, but I just wanted to see if anyone else had this problem. BTW, I am using a glass bed on my R2.
