¶ 4. Use grease to fully lubricate the optical axis and slider to ensure that there is no obvious resistance when sliding the slider and the slider does not wobble
¶ 5. When assembling the machine make sure that there are no gaps between the three shafts and the upper and lower housings. If there are gaps, the machine can be disassembled and reassembled.
¶ 6. Login to the web site and open the printer.cfg file.
¶ 7. Find the location of the red line in the figure below to increase the number of points for leveling detection, change 7 to 9 (note that the number of detection points modified must be an odd number)
