FAQ and Solution

Setup and calibration problems

Q: Temperature settings for several common filaments.
A: PLA: nozzle temperature: 200-220 ° C hot bed temperature: 50 ° C

ABS:Nozzle temperature: 230-235 ℃ hot bed temperature: 80-95 ℃

Q: What is the relationship between layer thickness, print speed and nozzle temperature?
A: The purpose of the interaction is to spare enough time to heat and cool of the filaments. Generally, if the layer

thickness increases, please lower the printing speed, the normal printing temperature (if the printing speed exceeds 60

° C, the temperature rises 5 ° C, exceeds 9 °C, increases 10 ° C ); If the layer thickness the contrary layer is reduced,

please increase the printing speed and reduce the printing temperature.

Q: How to set the best parameters when printing a model with sealed top and bottom?

A: Increase the printing thickness of the top or bottom in the basic parameters.

Q: How to set the parameters when printing a model with a single layer thickness?
A:Usually keep the layer thickness of the model more than 1mm

Note:

1. The layer thickness in the software can not be set more than 0.8 times the diameter of the nozzle (for example ,the
layer thickness should not exceed 0.32mm when the nozzle is directly 0.4mm).

Q: Is the warped edge on the model related to the joint problem?
A: : 1 hot bed leveling is not correct; please readjust the hot bed level.

2.If the filament is not attached the hot bed, please use 3M adhesive tape or high-

temperature adhesive tape to make it attach to the hot bed.

Q: Nozzle heating failed
A: 1.The heating tube is loosely connected, please check the black top wire and the heating tube under the heating block, insert the

heating tube and tighten the black top wire.

2 . Heating:

1) Open the case, find the connector of the heating tube, replace the connector, and then heat the nozzle again. If the heating failed

nozzle can work normally, which means that the heating tube is broken and needs to be changed;

2) With the replacement of heating pipe, the faulty nozzle still can not run, please replace the heating pipe, and try to change the

connection with the temperature controller, and reheat the hot nozzle. If the fault nozzle turns to be normal which shows that the
temperature controller is broken and need to be replaced.

3）If the solutions above is useless, it should be the problem of the power tube on the mainboard, please replace it.

Q: Maximum temperature / minimum temperature

A: 1. Nozzle temperature is too high.

Please reduce the nozzle preset temperature

2. The temperature controller is damaged..
Please replace the thermostat.

3. LCD line is loose / LCD line is damaged.

Q: The print head is stuck / can not move
A: 1 . Bearing is lack of lubricating oil.

Please clean the bearings and lubricate oil evenly.

2. Rack deformation caused by external forces during transportation.

3. The Y axis motor line is loose.
Please check the motor cable, reconnect.

4. Please check the fixed belt and screw in X axis and Y axis.
If you find the belt loose, tighten the belt, tighten the screws.

Q: Limit switch is inactive when zeroing or moving

A: Limit switch, the cable is loose or the switch is disconnected.

If the cable connecting the limit switch and the main board is loose, Please check whether the main board's terminal cable is correct. If
so, you need to pull out the terminal cable and reinsert it, if not, it means the limit switch is broken and needs to be replaced.

Q:Filament generate intermittent noise on the E-axis motor
A:1 . Feeding device is too tight, Please loosen the clamp screws

2. When the nozzle is clogged, the filament can not be fed smoothly. Use a drill or a needle to clean the nozzle

Extruder problem

Q:Blocking of the nozzel
A:A: 1. If there are impurities in the filaments, they will be melted in the nozzle, please use a needle to clean the nozzle; Or take down the

nozzle and use needle and drill to clean the inside of the nozzle.

2. If the nozzle is overheated, it will make the filament carbonized , please Use a needle to clean the nozzle; Or take down the nozzle and
use needle and drill to clean the inside of the nozzle

3. If the shape of nozzle hole is generated by external forces which resulting in deformation. Please change the nozzle.

Hardware problem

Q: Even if the screws on the hot bed have been screwed up to the top, the hot bed sheet is still too far away from the nozzle (the distance

between the hot bed and the nozzle is too far to adjust).

A: Adjust the printer's Z-axis limit switch, move the limit switch up a little.

Q:Z axis motion abnormalities.

A: 1 . The top of the Z-axis screw is loose, please check the Z-axis connection shaft and tighten the screw.

2. The connection of the z-axis motor is loose, Please check whether the main board is loose and plug the motor line again.

3. . The Z-axis screw needs lubricating oil, please use the lubricating oil to make the motor slide smoothly.

Printing problems

Q:The first layer has a printing problem.

Q: The directly heated cathode does not stick in the hot bed

- A1:The distance between the nozzle and the hot bed is too far.

- A2:The hot bed has not been leveled.
.-A3:The height of the first layer is too small, reommendation≥0.2

Q:Spin too less from the nozzel (only traces on the hot bed).

A: The distance between the nozzle and the hot bed is too close, which may result in the nozzle not spinning out.

Q: The nozzle does not print when printing.

A: The filament dose not enter the end of the nozzle, please wait for the filament input.

Q:Edge warped, use ABS material to print the material damage

A:Please keep hot bed heating and leveling hot bed, reduce the printing speed of the first layer, and avoid direct air blowing.

Q:The surface of the model is loose and with flaw

A: Layer thickness is too thick,print speed is too fast,
temperature of the hotbed is too low, wrongly choosing of the nozzel, stuck of the the filament, all of the problems
talked above will cause the situation.

Q:There is a leak on the side of the model

A: The temperature is too high or the material is carbonized or liquefied (if the temperature is too high, the PLA will is liquefy and the ABS will be carbonized.)
If the problem still could not be solved, please turn to after sales service.

Q: The surface of the model is not smooth

A: Turn off and pumpback .

Q:The model is easy to fall off

A: no adhesive tape or the tape loses stickiness; or the bottom of the model is too small;
It can be used to stick a hot bed with a heat gun; add support

Q:It is difficult to remove the support structure

A:In the slice software, rotate model direction correctly; do not set the support density too much

Q:Failed to print the mini-model.

A: Please do not set the model too small and the nozzle diameter is 0.4mm.
