When the extruder is homed, it will stay on the nozzle wiper, which can effectively prevent the extruder in standby state from overflowing when printing. The nozzle wiper may deviate from the standard position after long-term use or under external force, thus affecting the printing effect. Therefore, its position needs to be checked regularly.
Turn on the printer, tap Control > Move on the touchscreen, and then tap Home button .
After the left and right extruders have returned to their original positions, observe whether the nozzle end has completely entered the wiping pad and is pressed into the wiping pad for about 1 mm - 2 mm.
If yes, the nozzle wiper is already in the standard position; If not, pull the nozzle wiper by hand until it returns to the standard position.
