3D Printing - 06 Troubleshooting
Caution the hot Heated Bed. Always wear heat-resistant gloves while using the Heated Auto Leveling
or Heated Manual Leveling mode.
(3) Reset the printing parameters on Luban:
a. Set the Heated Bed Adhesion Type as Brim. Brim can effectively improve the rst layer adhesion. Also, you
can increase the line count to improve adhesion.
b. Lower the Initial Layer Print Speed.
c. Increase the Initial Layer Height.
d. Increase the Initial Layer Line Width.
e. Set a proper Heated Bed temperature as required by each lament.
f. Set a proper orientation and angle for the model to maximize its contact area with the Print Sheet.
(4) Clean the Print Sheet to keep it free of dust, cured laments, tapes, or other foreign matters.
(5) Clean the nozzle bore to keep it free of blockage and foreign matters.
(6) Dry the damp lament or buy new laments.
(7) Raise the ambient temperature using an air conditioner, enclosure, or heater.
(8) If poor adhesion persists, coat the Heated Bed with masking tapes or solid glues before printing.
6.2 Warping
Possible Causes
(1) The rst layer does not stick to the Print Sheet.
(2) The lament you use has high shrinkage, and is prone to warping during printing.
(3) The ambient temperature is too low.
Solutions
(1) See 6.1 First Layer Does Not Stick.
(2) Should you use ABS, here is a video tutorial to walk you through how to 3D print with ABS lament. Alternative-
ly, you can change a lament with low shrinkage like PLA and PETG.
(3) Raise the ambient temperature around the 3D printer using an air conditioner, enclosure, or heater.
6.3 Toolhead Hits the Heated Bed
Possible Causes
(1) The Y axes are assembled incorrectly.
(2) The X axes are assembled incorrectly.
(3) The 3D Printing Module is assembled incorrectly.
(4) The Support Platform is assembled upside down.
(5) The probe sensor wiring is worn out.
(6) The probe sensor is malfunctioning.
Solutions
(1) Check if the Y axes are perfectly mounted onto the grooves of the Base Plate. If not, place the Y axes right into
the grooves.
