Issue with BLTouch?

  • Hey guys,
    I’m new to 3D printer and I’m not quite sure if I should be worried or not, but the other day I was trying to print a model and the BLTouch that I installed didn’t stop the nozzle from hitting the bed and the motor made this horrible noise. It took me like 10 seconds to realize what was going on and I ended up just shutting off the printer. Before, the printer would save my Z-offset value even when i turned off the printer and now it doesn’t. Also whenever I preheat the nozzle it makes a very aggressive fan noise for a couple of seconds and then stops. I’m worried I messed up something inside the nozzle assembly, any idea what should i do? Should I be worried?
    thanks! - George
