Useful Tips While You Print
1. You can adjust the speed of your print in real me by turning the LCD screen knob. Slowing
the speed can be used to improve the print at a difficult area or if the print isn't cooling
enough.
2. You can adjust fan speed, hotend temperature and filament flow during a print. Note these
se ngs are not permanent and they will change when the printer reaches a new gcode
command or is turned off.
3. The cooling fan will not operate below 30% since the power is too low.
4. You can change filament during a print by just pausing a print. It can also be sent by your
host so ware or you can put it in your gcode file manually by pu ng M600 where you want
the change to happen.
When ac vated the print will pause, the extruder will raise/move out of the way and it will
retract the filament. Insert your new filament and press resume.
5. Always plug your printer and heated bed into a UPC power backup or surge protector.
6. When the nozzle is hot, carefully use needle nose pliers or the metal bristle brush to
remove any excess plas c which may have built up.
7. Do not use any lubricant on the lead screws, instead clean them off periodically with
acetone or rubbing alcohol. Lubricant will cause dust to accumulate and get s cky.

possibly damage the printer.
