General SLA 3D printer troubleshooting

Clean the build plate with isopropyl alcohol : A clean build plate is essential for good adhesion of the PCB. Use isopropyl alcohol to remove any residual resin and dust.

Check that all wires are connected correctly : Loose or incorrectly connected wires can cause a variety of problems, from lack of heating to erratic movement.

Test the printer with a different USB : Sometimes problems can be caused by a faulty USB. Try using a different USB and see if the problem persists.

Re-level the printer : An improperly leveled build plate can lead to poor print quality. Be sure to level the printer properly before each print.

Check that there are no errors in the .stl file you are trying to print : Errors in the .stl file can lead to failed prints. For example, due to missing support or incorrect slicer profile. Therefore, check this again, possibly with this test print file.
