2.2 Installation

5.1 Platform Leveling

The first time to use this printer, you need to level the platform. Please adjust the distance between the nozzle and the platform at points 1, 2, 3, 4. The distance should be just the thickness of a sheet of paper. (Please do this leveling with the help of adults.)

a) Click the [home-button] button, Z axis will go to home position. After Z axis comes to home position, please turn off the power. After turning off the power, then you can move the X axis and Y axis by hand.

b) Move the nozzle to point 1. Put a sheet of paper between the nozzle and the platform. If the distance is too far, turn the [adjustment-nut] counter-clockwise to make the printing platform rise to the standard distance. If the distance between the nozzle and the platform is too close, turn the [adjustment-nut] clockwise to make the printing platform fall to the standard distance. (Check the distance is right or not: when drawing A4 sheet, the nozzle should be attached to the A4 sheet without scratching it).

c) Do the same way to adjust another 3 points (2, 3, 4).

d) When the distance between the nozzle and the platform is right at all four points, leveling is finished and succeeded.

Please turn on the power again after platform leveling.

Illustrations A, B, C, D demonstrate correct and incorrect nozzle-to-platform distances: A (Good), B (Too far - the nozzle can't stick) [cross-mark], C (Too close) [cross-mark], D (Nozzle will be damaged) [triple-cross-mark].

5.2 Load Filament, Feed

(a) Insert filament into the print head tube until it can not go further, and gently press the filament to stop it runs back.

(b) Click the [feed-button] button. The button light turns on and flashes, the nozzle is heating. Please be patient and wait about 2 minutes. The machine begins to feed. When there is regular silk come out of the nozzle, feed succeed. Then you can press the [feed-button] button to finish feed.

Note: Make sure the distance between the nozzle and printing bed is 3cm at least. If no enough space, press the [z-up-button] button [hold-3s-release], Z axis will go up 1cm.

5.3 Print

Insert the TF card to the printer, Click the [play-button] button, and the button light will flash. Please be patient and wait about 2 minutes, printing starts (the Printer will choose the latest gcode file to print automatically).

5.4 Pause/Restore

During printing, Click the [pause-button] button, the button light stops flashing, then printing is paused. If need to continue print, Click the [play-button] button to restore, the button light flashes again, the printer goes back to print.

5.5 Stop Print

If you want to stop print during printing, press the [stop-button] button for 3 seconds then release, the machine will stop printing, then printing is cancelled.

5.6 Unload Filament, Retract

If users want to change filament or keep the machine stop working for quite a long time, then need to unload the filament. Click the [retract-button] button, the light inside will flash. Please be patient and wait about 2 minutes, the motor inside the head will work and draw out the filament, after that, take out the filament from the print head.

After print, remove the platform, and easy to take off the object.

High quality filament which is preferred to be used. Various of filament are available on the market, and quality is much different too. Poor quality filament may cause broken or nozzle jam, Please choose Easythreed high quality filament.

Safety Warning: Burning, keep your fingers away from the NOZZLE and BLACK INSULATOR when the printer is working as temperature in this area reaches over 200 Celsius degree. Always be sure to keep your hands away from moving parts when the printer is working.

Q1: Why is the printing model not adhesive to the printing bed?

A1: The nozzle is too far away from the bed, the proper distance between the nozzle and bed is the thickness of a piece of A4 paper.

Q2: Why the filament do not come out from the nozzle?

A1: Check the filament feeder. If it's an external gearfeeder, then to observe whether gear rotates or not. If it's a built-in stepper motor feeder, then to observe if the motor is working with a little sound. Otherwise, check if filament feeder is connected to its main board well.

A2: Check temperature. Printing nozzle temperature of PLA material ranges from 200-230°C.

A3: Check if the nozzle is blocked. Heat the nozzle to 230°C for PLA, push the filament gently. If there is still no filament come out, then need to disassemble the nozzle, clean or replace it.

A4: Check if nozzle is too close to platform. If so, the filament can not come out, so adjust the distance between nozzle and platform with a piece of A4 paper.

Q3: The problem of print model misplaced

A1: The model did not slice properly, need to re-slice or change the model position to generate new Gcode file.

A2: The model file problem. If the model is still misplaced after re-slicing, it's the original file problem.

A3: The nozzle is forced to stop printing Path: First, make sure you have not touched the nozzle when the machine is printing. Second, if there is filament residue on the top layer, the residue area will become larger gradually. When it accumulates to a certain amount and becomes stiffer enough, the nozzle will be forced to move abnormally.

A4: Power supply is not stable. Check if large power electrical equipment is working while the machine is printing. Dislocation happens when some equipment turns off such as air conditioner. If so, you need to connect a voltage stabilizer to the printer power supply.

A5: If the above solution cannot solve the misplace problem, the dislocation mostly happens at the same height for various models, then need to change the mother board.

Q4: Why the printing accuracy is quite different from the real model?

A1: There is a lot of filament piled up on the model surface.

A1.1: Nozzle temperature is too high, filament melts too fast and caused overflowing.

A1.2: The filament flow is too large. There is filament flow setting in slice software, change the default value 100% to be 80%.

A1.3: Filament diameter setting problem. It's in slice software. The default settings are different. There are both 1.75mm and 3mm filament on the market. For 1.75mm, the diameter should be 1.75. But for 3mm, the diameter should be 2.85 or 2.95.

A2: Poor surface after removing the support for FDM technology.

A2.1: The support density should be as lower as possible, 10% is proper, it's easy to remove.

A2.2: Trim the model with a grinding tool, rub gently with a towel and dip a little acetone. Make sure to wear gloves before hand, and do not wipe too long, to avoid the appearance being effected or dimension changed.

A3: The inappropriate distance between the platform and nozzle.

A3.1: The first layer is not formed, or the models are without edges or corners if distance is too large.

A3.2: The nozzle will scratch the platform and no filament come out of the nozzle if distance is too close. The proper distance is the thickness of an A4 paper.

A4: The inappropriate printing filament.

With the maturity of 3D printing, various of filaments are available on the market, but the compatibility for filament and printers are particularly important.
