Jog mode (X, Y & Z) and filament loading & unloading function help to check the condition of

  1. All stepper motors cable connecting stepper motor with a motherboard
  2. All limit switches and limit switch connecting cables with a mortarboard.
  3. Allegro chips
  4. Cartridge heater and thermocouple cable

1. Jog Mode:

Select setup => select Jog Mode => select X axis => up key (↑) to move right and down key (↓) to move left

Select setup => select Jog Mode => select Y axis => up key (↑) to move back and down key (↓) to move front

Limit switches are on the left, back and up when it touches limit switches it will stop moving. Other side rights, front and down do not have a limit switch.

2. Filament unloading function:

Select filament => select unload, it will start heating the extruder, after certain rise temperature, it will beep and start to rotate feed module stepper motor, now you can unload or pull out filament.

3. Filament loading function:
