1．Overview
1.1 Machine Overview
IEMAI's High-Performance 3D printer MAGIC-HT-M is a 3D printing device based on the
principle of fused filament deposition (FFF) technology, with a printing temperature of up to 450°C, a
hot bed temperature of 150 ° C, and a cavity temperature of 90 ° C. It supports most polymer 3D
printing materials on the market, including PEEK, PEKK, PPSU, ULTEM etc., creating excellent
temperature conditions to do great printing.. We have adopted a modular design, for example, both
the print head and the platform can be quickly disassembled, thus creating conditions for easy
maintenance.

2. Click the leveling button to use automatic leveling to
get the platform data. Wait for the printer to
automatically measure the platform 49 each test point.
3. Start printing and Z-axis compensation
After testing the printing platform, you can start printing.
If you find that the nozzle and platform spacing is not
ideal during the printing process, you can open and
change the data in the file of "Automatic leveling
compensation parameters" through Notepad, put the
changed file into the SD card, and use the 3D printer to
print this TXT file once, the compensation parameters are
changed.
