The maximum print speed is 200 mm/s, and acceleration is 10,000 mm/s². The flow rate of 60 mm³/s is specified for PLA at a speed of 100 mm/s and a 0.6 mm nozzle. The page also specifies synchronous material feeder control and calibration of the distance between the two nozzles on the XYZ axes.

Temperature Modes and Platform

In the standard configuration, the nozzle heats up to 350 °C. An option for 450 °C is declared for the model. The maximum platform temperature is 120 °C. The working chamber and filament box heat up to 60 °C. The platform has a PEI surface and magnetic fixation. The system supports automatic PID tuning. Temperature stability is specified within ±2 °C.

3D Printing Process Control

The model is equipped with a 10.1-inch color touchscreen with a resolution of 1280 × 800 pixels. The flash memory has a capacity of 32 GB, and the memory is 2 GB. Movement is controlled by an STM32 ARM Cortex-M4 with a frequency of 168 MHz. The logic controller is an RK3576 Octa-Core with Arm Cortex-A72 2.2 GHz and Arm Cortex-A53 1.8 GHz.

The list of functions includes automatic leveling, filament end detection, power outage recovery, automatic shutdown, and synchronous feeder control. Calibration of the distance between nozzles, magnetic platform, PID temperature tuning, and cloud OTA updates are separately specified.

Tips for Working with IEMAI LF YM-NT-750

• Before starting, check the condition of the PEI surface and the correct placement of the platform on the magnetic base.
• Run automatic leveling and monitor the first layer before transitioning to the main part of the model.
• When working with two nozzles, check the calibration of the distance on the XYZ axes.
• Select the temperature according to the profile of the specific material and do not exceed the printer's configuration limit.
• Use 1.75 mm filament and do not heat the box above 60 °C.
• For a new material or profile, first print a test sample.
• Determine ventilation requirements based on the material's datasheet and manufacturer's instructions; the model page does not describe an air filtration system.
• After cooling, inspect the nozzle, guides, belt, linear module, and ball screw according to the manufacturer's regulations.
• Do not disable the filament sensor, automatic shutdown, temperature control, and other factory protective functions.
