Tips on some possible no error code issues:

 Noise while moving up and down

Check the 4 screws holding Z motor and make sure they are tight; (The 4 screws are right behind vat)

Apply engine oil on Z axis rod;

Z moved up over top CAP manually and as such can't move down

Power off and remove power cord.  Then use fingers to manually twist the z rod back into its top CAP till you see the rod comes out on top.  Then power on and hit home button.

Avoid manually move up too far.

The skipping sound while moving down in this situation is normal.  It is a protection mechanism.  No recalibration needed after this fix.

Can't power on printer

Remove back panel and check the power switch connectors. If loose, reseat them.

If above won't work, remove bottom panel and inspect further along the power cable to the green connector on mainboard.  Gently pull the two power wires to make sure they are secure in the green connector.  Reseat the green connector if loose.

If the power wires going to mainboard are loose, pull off the green connector and secure the wires (unscrewing the two screws on the green connector, insert wire further and tighten the two screws on the green connector).

Touchscreen works but no light on LCD

1. Open back panel

2. Run the light calibration test using touch screen

3. Check the bottom of light cup to see if any light comes out around.  

4. If light is not seen around bottom of light cup, open bottom panel and check the wires from mainboard to light drive.  This is the second green connector on mainboard.  Gently pull the wires to make sure no loose wire.  If loose, secure them same way as above.

LCD has black spot/area while it should show the layer of print

Replace LCD.  Wear goggle and glove while replacing LCD as it has thin tempered glass.

 

 

Typical Printing related issues:

 Layer shift to front/back Secure build plate
Layer does not stick to build plate

Many possibilities:

First of all, please filter the resin in vat and clean up vat to make sure no residues in vat.  Any residues can poke film and even damage LCD screen.

1.  Bottom exposure time is too low for your resin.  Ask in facebook group if anyone else used this resin on EPAX before.

2.  (This is rare) Build plate not leveled.  Before suspecting this, please remove vat, put a piece of paper on LCD and do an auto home to see if the paper is tight.  If not tight, you can manually go down further 0.1mm and set it as new zero position.  This will not harm your printer and will never push LCD screen, even if you lowered too much. 

Film is damaged

Most likely cause is residues in vat.  Please filter resin in vat and replace film according to video in support section of epax3d.com

Might also get damaged by scratching or mixing resin.  Probably get a silicon tool to mix resin or use the auto-mixing gcode developed by Sen Kun.  Ask support if you need to find it.

Overtime scratching or fine residues can leave marks on film.  Consider replacing film if it wears out.

Film damaged and resin leaked on LCD screen Replace film.  Use IPA to soak the hardened resin on LCD screen for at least 30 mins.  Then wipe off or shovel off.  Do not let IPA or resin going to the edge of LCD screen.  That will leak under LCD.
Film damaged and resin leaked into LCD along LCD screen edge Replace LCD.  Replace film.
