The following tips are things I've seen greatly resolve charring issues: 


* Update firmware (how-to)

* Experiment with how you're packing your crucible

* Adjust rate and speed of your draw

  • The technique of hitting an on-demand vape is different from hitting a session vape, joint, bong or piece
  • A 10 second steady inhale will produce the intended results 

* Check for air bypass 

* Do not remove battery from device mid-session

* Manually Calibrate to have machine run cooler than default (how-to)
