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 use the "Tune" menu to adjust fan speed, hotend tempera-
ture and filament flow during a print. Note these se ngs are not
permanent and they will revert to standard se ngs when the
printer reaches a new gcode command or is turned off.
3. The cooling fan will not operate below 30% (or 76 from the LCD menu) since the power is
too low. You should not set your fan over 85% or it may cool the hotend.
4. You can change filament during a print. Go to
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 in the gcode.
When ac vated the print will pause, the extruder will raise/move out of the way and it will
retract the filament. A er 3 minutes, the extruder will turn off for safety. Insert your new
filament and push the knob to 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 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.
8. Check your print o en. If any part of the print fails, it may destroy the rest of the print and
possibly damage the printer.
9. We recommend using the cold acrylic bed whenever prin ng with PLA for improved adhe-
sion and enhanced cooling.
10. Do not use solvents to clean acrylic or BuildTak PEI print bed.
