G12 Common Problem FAQ
Table of Contents
Leveling Issue
1. Large error after auto leveling
- Check that the ground on which the machine is installed is level, we can adjust the four wheels at the bottom.
- Take out the glass, re-fix the heating plate at the bottom. Then reinstall the glass and check that the glass is level.
- The heights of the left and right sides of the Z-axis are inconsistent, need to adjust the Z-axis lead screws.
2. Nozzle does not print after leveling
- Check the ‘home’ function is normal, then recalibrate the gap between the origin and the nozzle through the Z-offset function.
- Check the printing file is normal, slice it again.
Extruder Issue
1. Pellets stuck
- Check the setting temperature of the extruder 1 and extruder 2 is corresponding to the pellets need. Extruder 1 is the lower end temperature, extruder 2 is the upper end temperature. Usually the lower end temperature is 5-10°C higher than the upper end.
- Open the feed transition board on the side to see the extrude screw is spinning. If not, that means the extrude screw and motor coupling are loose. If yes, that maybe the pellets in the extrude screw are stuck, need to clean the extrude screw.
2. Extruder motor shaking
- Check the extruder motor cable is loose or poor contact.
- Driver dial incorrect.
3. Extruder motor not working.
- If not working when printing, maybe the Creality print software version is old, needto update the software or use Simplify and Cura.
- Check the extruder motor cable on the mainboard is loose.
- If cable is good, need to change a new motor.
Printing Issue
1. Printed model warping
- Check the model contact area, if the area is small, we advise to add a base under the model or rotate the model in the software.
- The nozzle far from the platform, need to adjust the Z-offset.
- Some special materials like: PP&PC, they are prone to warping and have bad adhesion, need to smear special platform glue on the platform before printing.
- Some materials need a constant temperature environment, we advise you to close all the doors before printing.
2. The surface texture of the printed model is obvious
- Check the nozzle temperature is over high, need to increase the temperature.
- Check if there is overlapping between the layers, if yes, need to decrease the extrude flow.
- The printing speed is too fast. We can decrease the printing speed on the machine to 80-90.
3. Printed model layer shift
- Check is left-right layer shift or front-back layer shift first:1)If is left-right layer shift, need to check the X-axis timing belts and timing pulley are loose.2)If is front-back layer shift, need to check the Y-axis belts and reduction gears are fixed well.
- If models are layer shift at same height, check the Z-axis at that height is slippage or poor movement.
4. Printed model incomplete
- The supports number are not enough, need to add more supports.
- If the model wall thickness is less than 2mm, the printing effect will be bad, ensure the wall thickness is over 2mm.
- Maybe the nozzle temperature is too low, makes extrude not enough.
5. Printed model keeps tilting
- Check the model is tilted forwards to X-axis or Y-axis. If tilted forwards to X-axis, that means the X-axis SSD has problem. If tilted forwards to Y-axis, that means Y-axis SSD has problem.
6. Printed model size deviation
- Test the XYZ axis real size first. If which axis real size is smaller than design size, we need to increase that axis motor step value. If which axis real size is larger than design size, we need to decrease that axis motor step value.
Z-axis abnormal
1. Z-axis keep rising
- Zero first, check the z-axis is working normal.
- Check the CR-touch light color. If is red, that means CR-touch abnormal, need to reinstall the cable and reboot the machine. If is purple, that means normal. If no light, that means CR-touch broken, need to change a new one.
2. Z-axis shaking and does not rise
- Check the motor cable is loose.
- Check the driver cable is normal.
Pellets can't be sucked up
1. Pellets can’t be sucked up when feeding
- Check the air pump is working normal.
- Check the air pressure on the air pressure gauge is over 0.8Mpa.
- Check the hopper cover is install good, otherwise there will be air leakage.
2. Pellets not sucked enough when feeding
- Check if the air pressure of the air pump is not enough, need to change a more lager power air pump.
- Check if the air tube is air leaking.
U disk reading issue
1. Suspected U disk broken
- Change a new one to check is the U disk problem or the interface problem.
- Try to format the U disk and insert again.
2. No reaction after insert U disk or can’t find the files
- Format the U disk.
Mainboard\Display Screen\Power Issue (Professionals Only)
1. Mainboard have problem.
- Send it to our aftersales engineer to check.
2. Display screen blurred\black\white\ twinkle
- Check the display screen cable, remove high frequency interference sources.
3. Suspected power supply problem
- Check the voltage switch is dial to your area voltage range. (110V\220V)
- Check the cable is normal.
- Contact with us.
Components broken\Send wrong\Missing Send
- Contact with our aftersales engineer.
Pellets maintenance
- Dry pellets: If open the pellets package for a long time, we need to use a drying box to dry half an hour.
- Pellets recycle：After printing finish, If it is not printed for more than 3 days, it is recommended to recycle the pellets in the hopper in time.
