【Removable Capacitive Touchscreen】The 4.3-inch removable magnetic capacitive touch screen can be operated by hand-held or fixed on the base, with a print model preview function to preview the model image during printing and observe the printing progress, support multi-language freely switch. There also comes with a drawer tool box on the machine base to store tools used by the printer such as Allen wrench and nozzle accessories.I slid everything inside a wooden box with plexi glass shoots. A Uno and a Adafruit motor shield run the motors. Using two 5mm x 8mm motor shaft couplings, I connected them to Nema 17 12V motors with motor mounts mounted on a board. The 420W high-power hotbed can quickly heat up to 100☌. I cut the knobs off of the 'D' shafts that go into the paddles. 【PEI Magnetic Platform】PEI magnetic platform with a special coating and spring steel sheet for strong adhesion and anti-warping, so you can easily remove or eject the print models by slightly bending the print steel sheet.

if you want to move 20 steps then you will move 20 1.8 36 degrees. if you want to move 20 degrees then you use 20 0.55555 11 steps. Incrementing specific rotation is what stepper motors do. This allows him to tap the volume up or dn button and the motor will increment accordingly. With an STM 32-bit silent motherboard, the X/Y/Z/E axes are all driven by high-precision stepper motors to effectively reduce the printing noise under 50 dB. if there are 200 steps in 360 degrees then there is 360 / 200 1.8 degrees per step. A stepper motor was the best choice in my opinion.Next, grab the push button, rotary encoder knob, LCD screen, and the 3D printed top.

【Stable & Quiet Printing】The Z-axis is designed with dual lead screws and dual-motor drive for more stable and precise movement of the print head, and the double tie rod structure enhances the stability of the Z-axis gantry. Arduino Nano A4988-stepper motor driver module NEMA 17 stepper motor 13/64-inch (5mm) ID timing pulley.

You can also use the hand-twist knobs under the build platform for auxiliary leveling to achieve a nice first layer.

【Auto Bed Leveling + Auxiliary Leveling】The non-contact high precision sensor automatically scans 63 points of the hotbed to compensate for any unevenness and inconsistencies of the printing platform.

【Massive Print Volume】With the largest ever build volume of 420x420x500 mm /16.53x16.53x19.68 inches, ELEGOO Neptune 3 Max gives you generous printing space to let your creativity run wild, whether for printing larger models, or printing in batches. / MotorKnob - slightly modified A stepper motor follows the turns of a potentiometer (or other sensor) on analog input 0.

Ideal for printing PLA, PETG, ABS, and flexible filaments such as TPU. The wire connections from the top left corner of the stepper shield to the Arduino are as follows: GND to GND STEP to Digital 2 DIR to Digital 3.

【Dual-Gear Direct Extruder】The dual-gear direct drive extruder with gears made of SUS303 stainless steel features adjustable extrusion force and a 3:1 reduction ratio, which ensures smoother filament feeding and stable & accurate printing, greatly reducing nozzle clogging and gear jumping problems.
