PRINTING

1. Platform Leveling

For the first time to use this printer, you need to level the build platform. Please adjust the distance between the nozzle and the platform in (1) (2) (3) (4) points. The nozzle height above the build platform should be 0.1mm, which is the thickness of a sheet of A4 paper.

1. Click the button, Z-axis will move to the home position.
   please turn off the power. after turn off the power .then you can move the X-axis and Y axis by hand
2. Move the nozzle to point (1). Put a sheet of paper between the nozzle and the print platform. If the distance is too far, please turn the hand-twisted nut count­er-clockwise to make the print platform rise to the standard distance. If the distance between the nozzle and the platform is too close. please turn the hand-twisted nut clockwise to make the printing platform fall to the standard distance. (check the distance is right or not. That is, when drawing A4 sheet, the nozzle should be attached to the A4 sheet without scratching it).
   
3. Follow the same way to adjust another 3 points ee.
4. When the distance between the nozzle and the platform all is the right distance in (1) (2) (3) (4) four points, leveling is finished and succeeds.
   Please turn on the power again after platform leveling

FAQ

01: Why is the printing model not adhesive to the printing bed?
Al: 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?
Al: Check the filament feeder. If it’s an external gear feeder, then observe whether the gear rotates or not. If it’s a built-in stepper motor feeder, then observe if the motor is working with a little sound. Otherwise, check if the filament feeder is connected to it’s main board well.

A2: Check temperature. Printing nozzle temperature of PLA material ranges from 180-230 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 the nozzle is too close to the 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
Al, The model did not slice properly, need to re-slice or change the model position to generate a 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 become stiffer enough, the nozzle will be forced to move abnormally.
A4, the Power supply is not stable
Check if large power electrical equipment is working while the machine is printing. a dislocation happens when some equipment turns off such as an air conditioner, if so, you need to connect a voltage stabilizer to the printer power supply. Otherwise, observe if the nozzle is blocked at a certain position, if so, the power supply on X, Y.Z axles are not even, then need to adjust the X.Y, Z electric current on the mainboard.
AS, If the above solution can not solve the misplace problem, the dislocation mostly happens at the same height for various models, then need to change the motherboard.

• Why the printing accuracy is quite different from the real model

Al, There is a lot of filament piled up on the model surface
Al.l, Nozzle temperature is too high, filament melt too fast and caused overflowing.
A1.2, The filament flow is too large, there is a 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 beforehand and do not wipe too long to cause the appearance affected 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 the distance is too large.
A3.2. The nozzle will scratch the platform and no filament comes out of the nozzle if the 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.

FAQ

Q1: why the printing head can not move after pressing the printing button in initial printing?
A: Please remove the clips in the front left and right corner before using the machine. The clips are or transportation protection

Q2:How to feed the filament and how to judge filament feed successfully?
A: First, straighten the filament and gently push it into the feeding hole, at the same time, use the other hand to operate the screen to “in filament” choose it and confirm. Then wait about 1 minute(the machine is warming up), release the material when feeling the filament is caught by the machine. Then wait another 10 seconds to observe if there has “silk” coming from the machine. There is about 10cm filament come out. Till this time, filament feed successfully.If you operate based on the above steps, but no silks come out from the nozzle after waiting for more than 5 minutes, please re-power the machine and try again.

Q3: How to retract filament? How to solve when the filament can not be retracted

A: slide the back gear to ‘retract’ gear, normally this way will retract successfully, if failed pls try to feed first,  then retract again. Please Pay special attention that, gently pull up the material to help till the filament completely get out of the printer head.

Q4: What’s the reason that the model can not stick to the printing bed in the initial, printing or in the process of printing?
A: The gap between the bed and the nozzle is too far, you need to level the bed, use the method we mentioned above( 4.4 article)

Q5: What needs to pay attention to when adjusting the printing bed? Need to check a bed Before each print?
A: adjust the printing bed, need to use the screwdriver in the accessories box to rotate the bed screws when rotating clockwise the bed goes down when rotating counterclockwise the bed go up.
No need to always adjust the leveling with every printing.
How to leveling pls refer to above mentioned(4.4 article)

Q6:How to judge what’s the best distance between nozzle and printing bed? What is the difference when its too close and too far?
A: The standard distance between the nozzle and printing bed is the thickness of a piece of A4 paper, Insert a  piece of paper between the bed and the nozzle, with normal pull and with resistance as the standard; in the condition that does not scratch bed. The closer it is, the firmer the model will be.

• The right distance between nozzle and bed: the” silks” are flat, spread on the bed very smooth, and no burrs.
• The distance is too far: the “silks” are round, spread on the bed unevenly, with gaps and tilt. Filament
  comes down to the bed is by gravity force. The rounded strips’ adhesion effect is not good, they are easily moved. The printing effect is very unsatisfactory.
• The distance is too close: the “silks” are irregular protrusion(with burrs)on both sides, but thin in the middle. Or there are no silks coming down. Or the bed is scratched with a deep trace.

Q7:Why do there twist lots of filament nearby the nozzle in the process of printing? Does the model become a mess of silks?
A: there are several situations:

• When it happens in the initial printing, the distance between nozzle and bed is too far, the silks can not stick to the bed, so it would become messy filament. Please twist the 4-bed screws 90 degrees anti-clockwise. If still not ok, then please twist 90 degrees anti-clockwise again till normal printing.
• The bed is with oil, please use a dry towel to tidy the bed, do not use your hand to touch the bed directly.
  Q8:How can i move the printing head X, Y?
  A: Please unplug the power, then use your hand to move the printing head to where you want. Please do
  not try to move the head up and down, Z-axis can not be moved by hand.

Q9:How can i move the printing head up?
A: Only in the condition that the printer is power on but is not printing, press the printing bed for 3 seconds then release, it will go up 1 cm.

Q10:Does the printer need warming up before each printing?
A: There needs to warm-up when feed and retract operation, In normal printing, you only need to choose the model and wait about 1 minute, then the printer will start work.

Q11:Can the model continue printing if electricity is cut off?
A: If there is no electricity in the process of printing, the models can not continue printing.

Q12:Can pause printing in the process of printing?
A: Yes, press the printing button, it will pause. Then press again,it will continue printing.

Q13:How to stop printing?
A: Please press the printing button for 3 seconds then release, then it will stop printing(precaution:can not continue printing after a stop).

Q14:Filament will run out soon in the process of printing, What should do?
A: Please pause the printing, then slide the switch to retract gear, use your hand to pull up the filament.(precaution: please do this before all the filament goes into the feeding hole, or there will be no filament hand can pull up). Then put the new filament into the hole and use another hand to slide the switch to feed gear, wait about 10 seconds till the filament come down. Then slide switch to the middle gear and press the printing button shortly to resume printing. Please pay special attention that, after feeding 10 seconds, timely slide switch to the middle gear in avoid that the filament pimple appears in the model.

Q15:When print the first layer, there is no filament on the bed, why?
A: Please check if the distance between nozzle and bed is to close cause no space for the filament to come out.

Q16:Can the_machine print online?
A: Yes, it needs to use third-party slicing software CURA. Please refer to the above step of point 5.0 Online printing(For experts)
