• Slow down the print. This can be done by twisting the knob on the front of Altair counter-clockwise.
  • Raise the temperature of the hot end. This can be done in MatterControl by changing "Extruder Temperature". Moving it up in increments of 5 is a good place to start.
  • Ensure that you are using the proper temperature and/or heated bed if necessary for the material you're using. Adjust accordingly.
  • Adjust the extruder pressure. This can be done by twisting the screw on the extruder shown below. Twisting to the right will increase the pressure. Twisting to the left will decrease pressure.
