Page 3: Safety Precautions
Safety Precautions 1) The temperature of the nozzle parts can reach 250 °C during the operation of the machine. To ensure your safety, it is forbidden to touch the model and nozzle directly with your hand while the printer is printing or cooling. - Page 4 The front end of the consumable should be fixed on the tray to avoid consumables and affect the next print. To use this printer, it is recommended to use the supplies provided by the company. At present, the quality of consumables sold in the retail market is uneven, and printing is prone to breakage.

Page 21: Model Selection
(2) Model selection Open the software and choose the language you want According to the model of the machine purchased, select the corresponding model. Incorrect selection will cause the machine parameters to be incorrect and the printer will not work properly. If it is a machine of another brand, you can also choose other models for related settings or use it. -
Page 22: Software Usage Introduction
(3) Software usage introduction 3D printer supports gcode format files, so you need to import the STL format model into Changlang 3D slicing software for slicing operation. To print a fine model, you need to have a deep understanding of the slicing software that controls the print path. -
Page 23: Export Gcode Format For Printing
Nozzle aperture: 0.4mm. Retraction speed: the speed of retraction when printing the model. Retracted length: The length of the material withdrawn, generally 4.5 ~ 8mm. Initial layer thickness: Print the thickness of the first layer, which is the default. Initial layer line width: 100% will be thicker and denser, just default. Bottom Cut: The length of the bottom cut of the model. -
Page 24: Instructions For Printing Online
D. Instructions for printing online Changlang 3D printers support online printing operations, but because the computer sends instructions continuously for a long time, there are many different settings on the personal computer (some computers will set the energy-saving mode or the screen mode, etc.) and the computer will freeze if it runs. -
Page 25: Online Printing
Open the Changlang 3D slicing software. The first step is to turn on the model. The second step is to open the model settings. The third step is to select the serial port number displayed by each computer. Generally, the larger serial port is selected. Normally select "AUTO" for the special rate. -
Page 26: Professional Settings
(4) Professional settings If you want to print a more professional page online, you can set it by the following steps. Select file in the first step, select parameter settings in the second step, and change the print window settings in the third step to professional. Then start printing the page online and it will become a professional page, you can send G codes, you can control the movement of each axis. -

Page 29: Guide To Common Problems In Machine Use
F. Guide to common problems in machine Question 1: How to update the firmware? Sometimes individual DIY users want to add some special functions to their 3D printers, or there are unknown bugs in the original firmware, then the firmware needs to be updated, and each machine will be sent to the user after strict and detailed factory inspection and burn-in. -

Question 3: When the machine returns the filament, it can't be returned. What should I do when stuck in the pneumatic joint? 1. Before returning the material, please heat the nozzle first, and then withdraw the consumables as soon as possible. If you can't pump it, you can re-feed the material with the advanced material, and melt the extruded block formed at... -
Page 32: Question 5
Question 4: What should I do if I cannot resume printing after power shutdown? If the power is suddenly turned off when the part is first printed, the machine will not save the print data. Unless the height of the print exceeds 0.5mm, the power failure will be supported. - Page 33 Question 6: After the machine heats up, the filament is discharged normally. However, when the printing is performed for the first time, the curling occurs on the platform. After printing several layers, the filaments get 1. After the user gets the 3D printer, if the leveling is found to be curled on the first layer of silk, it feels like it is gently falling on the platform.

Do you have a question about the LK 5 PRO and is the answer not in the manual?
Questions and answers
Is the print head supposed to be loose ? when leveling can get corners good but when center check it seems tighter. I can wobble the print head on the track.
@Milton Green mine is just the opposite, tight on corners and loose in middle. fixn to buy a different machine. although the customer service is A+ exceptional the machine is not. I have to level table every print and sometimes is wont make it through the whole print before it gets out of level. and you can see it in the prints bad.
No, the print head on the LONGER LK5 PRO is not supposed to be loose. A loose print head can cause print quality issues and improper movement. It should be firmly secured to the gantry, with proper adjustment of the eccentric nuts to ensure stable movement without being too tight.

when printing the filament feeder has started making a clicking noise and it is not able to feed the filament through. Ive unloaded and re loaded it multiple times and during the load filament action the filament is coming out of the nozzle as it should but during the print it will not
The filament feeder on the LONGER LK 5 PRO may make a clicking noise and fail to feed filament due to one or more of the following reasons:
1. The filament may be tangled or wound, causing resistance and preventing smooth feeding.
2. The nozzle could be blocked, possibly due to impurities in the filament. This blockage can prevent filament from passing through, leading to a clicking sound from the feeder mechanism.
3. The gear in the feeding mechanism may be slipping because it cannot push the filament through the blocked or restricted nozzle.
To fix this, check for tangled filament, heat the nozzle, and use a 0.4mm needle to clear any blockage in the copper nozzle.

Screen is not turning on
The screen of the Longer LK 5 Pro is not turning on because there is no voltage present on any pins of the cable going to the LCD. The exact cause is unclear, but it could be due to a power supply issue, a damaged cable, or a problem with the mainboard.

I lost one of the tiny screws which secure the filament breakage detecter sensor. I rigid like to know what size those are so I can replace it.
where is the micro sd card slot I HAVe looked at the back on the one side and low and behold NO SLOT!
