Provides you with the ability to cultivate creative thinking. Read more 90% Pre-Assembly Lock 6 screws to complete the installation, to meet the needs of professional customers for quick assembly, but also friendly to beginners. Simple wiring design Use two CAT 7 Ethernet cables RJ45 to transmit data. Say goodbye to tedious wiring steps and farewell to messy cables. Reduce the safety hazards caused by exposed wiring harnesses. Control box skylight design Change the traditional bottom-placed motherboard structure, upgrade to a skylight structure. Easy to disassemble and replace parts, convenient for maintenance. (Note: When disassembling and replacing parts, please turn off the power operation) Read more Automatic leveling The automatic leveling feature saves you the hassle of manual leveling. Simple and easy to use, the intelligent leveling system can automatically compensate for the printing height at different points of the hotbed. Removable Build BLU-5 3D printer is equipped with PEI magnetic soft bed. Strong adhesion, easy mold pickup and reusable. Adaptive pulley Automatically adjust and fit the aluminum profile, no need to worry about the shaking of the pulley affecting the printing accuracy.

Err1: The hotbed exceeds the maximum temperature limit, please check whether the thermistor is short-circuited; Err2: The nozzle exceeds the maximum temperature limit, please check whether the thermistor is short-circuited; Err3: The hotbed exceeds the minimum temperature limit, please check whether the thermistor is disconnected; Err4: The nozzle exceeds the minimum temperature limit, please check whether the thermistor is disconnected; Err5: The print head fails to heat up. If the print head does not reach the set temperature difference within the set time, an error will be reported; please check the configuration file settings or check whether the power supply is sufficient; Err6: The hotbed fails to heat up. If the hotbed does not reach the corresponding temperature within the set time, an error will be reported; please check the configuration file settings or check whether the power supply is sufficient; Err7: Thermal runaway; when the temperature rises to the target temperature if the current temperature fluctuates greatly within the set time, an error will be reported; please check whether the thermistor is normal or whether the PID value is appropriate. Tips: During use, please pay attention to the key components of the 3D printer (such as hotbed and extrusion head). In this process, the heat will generate a high temperature to avoid scalding! The 3D printer has a high-voltage power interface such as 220VAC / 110 VAC. Please be careful. Avoid electric shock! The key components of the 3D printer (such as hotbed, extrusion head, etc.) have relatively high power. During this process, please ensure that the terminals are firmly connected to avoid sparks due to loose wiring, which may cause a fire. To ensure safety, please avoid unattended printer operation for a long time! The 3D printer is a kind of mechanical equipment. Please stay away from moving parts during the operation of the machine to avoid mechanical damage! Please lubricate and maintain the guide rail regularly.
