Product issues

● Check the power supply.

● Change the SD card.

● Check the power supply.

● Check the Slicing problem.Print a different type of simple model to test it. It can't be printed normally. If it can, then it may be a model problem.

● Check the connection cable between motherboard and motor

● Check the X/Y/Z axis voltage by the multimeter

● Re-tighten the screws

● Clean the fan.

● Change the fan.

● Check output voltage in the plug. If it is the current problem, just change another power supply.

● Check fuse.

● Re-tighten the connect cable  

Check the thermal bed and nozzle thermal to determine whether the heat is a problem, if it is, replace it.

Screen issues

● Check the connect cable and re-tighten it

● Check if the cable shielding tape is normal.

● Remove high frequency interference sources.

● Apply for a replacement display.

● Check the connect cable and re-tighten it

● Multiple machines adjust the screen to determine whether the motherboard or scree problem

● Demagnetizing the screen is magnetized and replace the cables.

● Check the shielding tape of the cable is damage or not.

● Is there high frequency interference nearby?

● Replace the motherboard

Wipe the screen with a damp cloth, taking care not to touch the power-on original.

Print issues

● Clean the build plate, FEP and resin.

● Level the build plate.

● Adjust the settings for your first layers.

Increase your layer cure time to 150 seconds.

Increase the number of “first layers” to about 6 layers.

Decrease your first layers height to about 20 – 40 microns.

Reduce the lift speed of the first layers.

Increase the lift distance to about 10mm.

● Roughen the surface of the bed/ build plate.     

Warning: Be careful not to overdo it by making it uneven!

● Change the FEP layer.

● Change your print settings.

● Change your FEP film.

● Change your 3D model.

● Change the resin.

● Change your cure settings.

● Ensure parts are well supported and constrained during the printing process

● Turn up the cure time for each layer and increase the dwell time before each lift.

● Try to orient parts to print tall rather than wide.

● Take a more gentle post-cure approach.  Use a diluted IPA (let’s say 70% IPA, 30% water) for a shorter time period and cure using a less aggressive light source, (maybe placed further away) or for a shorter time.

● Worth considering to constrain the part for post-cure if it becomes a problem.  That might help to hold it’s shape.

● Also consider different resin options.  Some resins have less shrinkage than others, which would also help.

● Design the print for success.

● Use a more appropriate resin.
