For some reason my BigBox dual hybrid has started air printing. I run mesh levelling and level over 9 points on the bed. When that's done it goes through the auto-home procedure and I save to memory. Yet when I print via OctoPrint it is like it's totally forgotten the MBL settings and it's running the IR probe settings. After having weirdness with the MBL I upgraded to RC8 in the hope it would magically resolve. All upgraded fine but now it's printing a good 30mm higher than the glass bed. Any ideas on what's happening here? I have run MBL at least 10 times. I always save to memory after the tedious 9 measurements with paper between the nozzle and glass. The bed itself is reasonably level. Restarted the box a few times. Yet still the same result. It's strange to me that at the end of the MBL it homes and does the Z home with the IR. Why is this so when I just levelled with the MBL? I get the X and Y, but the Z by IR seems like it's unnecessary? Could that be replacing my fresh MBL settings?
