STEP1: Check the power line and other wires are connected well or not.

STEP2: Check whether the supply voltage suits the local standard.

STEP3:Check whether the screen or power supply is damaged and replace it in time.

STEP4: Check if the wires are damaged or broken.

STEP5: Check whether the power fuse is burnt out.

STEP1: Check the card reader if it is good.

STEP2: f the computer can’t read the SD card, please format it and try again.

STEP3: Check whether the SD card is inserted correctly.

STEP4: The filename has an illegal character. Please rename it.

STEP5: Please replace the damaged SD card and try again.

STEP1: Check whether the print head temperature reaches 200℃ above (PLA), led to filament cannot squeeze, waiting for the temperature rises to the set target. 
 
STEP2: Check whether the filaments are knotted, which leads to unsmooth feeding. 
 
STEP3: Check whether the filaments or pipes are not inserted in place, failing to feed.   

STEP4: Check whether the temperature of the print head is too high, which leads to the excessive softness of filaments and can’t be extruded usually.   

STEP5: Check whether the diameter of filaments is consistent with the diameter set in the slicing software so that the amount of extrusion filaments is not enough.  

STEP6: Check whether the consumables are blocked by dirt or nozzle blocked during extrusion.

STEP7: Replace with better quality filaments.

STEP1: Check if the hotbed has been leveled well.   

STEP2: Check the surface of the hotbed for dirt.   

STEP3: Check whether the distance between the nozzle and the platform is too high, resulting in insufficient adhesive force.  

STEP4: Check the hotbed for adequate temperature.   

STEP5: Check the first layer of the slicing software to see if it is printing too fast. 

Step 1: Try to heat the hotbed to 50-70 ℃ take it off by the shovel. 

STEP2: It is recommended to buy TRONXY magnetic stickers. 
 

STEP1: Check the heating rod and thermistor for poor contact or damage.   
 
STEP2: Check that the slicing software has set the target temperature.   

STEP3: Check whether the thermistor wire falls off.

STEP1: Check the tightness of the belt, whether the pulley is not locked.    

STEP2: Check the current-voltage.    

STEP3: Check X/Y/Z axis motion is smooth.   

STEP4: Print speed too fast.

STEP5: Environment temp too high.

STEP6: We need to flash the firmware.

STEP1: Check whether the motor line is in bad contact, loose or wrong connection.   

STEP2: Motor temperature is too high.  

STEP3: Check whether the motor is damaged.

STEP4: Flash the firmware.

STEP5: The printing load is too heavy.

STEP1: Nozzle feeding not smoothly; please clean the nozzle or replace the nozzle.
 
STEP2: Check that if the printing speed is too fast.

STEP3: The quality of filaments is insufficient. Please replace them with new filaments.

STEP1: Please check whether the nozzle is blocked.

STEP2: The nozzle feeding is not smooth; please clean the nozzle.

STEP3: Whether the software Settings are incorrect.

STEP4: Check whether the motor does not work.

STEP5: Check the motor working or not or feeding gear is not working.

STEP1: No screen/blue screen; please restart or check whether the cable is plugged in.

STEP2: Touch screen malfunction; check whether the screws are installed too tight.

STEP3: Garbled/splash screen, static, ground connection, or restart.

STEP1: The wiring is not responding. Please check the wiring installation.

STEP2: Automatic shutdown restart, maybe abnormal firmware or module of “resume print after power failure” damaged.

STEP3: Lack of heat dissipation, please lower the ambient temperature.

STEP4: No response due to motherboard hurt.

STEP 1: Check that the driver is not installed or adequately installed.

STEP2: It can’t select the serial port.

STEP 3: The software parameters do not match.
