Support Slash Trouble Shooting

The calibration for platform initial point is not in correct position

Follow z-axis calibration procedure and calibrate again.

Build platform surface is too smooth, printed model falls into the resin tank

Use provided sandpaper to roughen the surface of the build platform and clean up.

The suction force between the resin tank film and models is too strong

Replace with a new resin tank.
Or remove the resin tank, clean the LCD panel and the bottom of the resin tank film; wipe them with alcohol and then with a dry paper towel. (Note: touch ONLY the glass part of the screen, the area covered with black tape should not be touched).
Increase cool down time.

Insufficient adhesion between printed layers

Increase exposure time

The LCD cable is not inserted properly; damaged LCD cable

Follow the guidance to re-insert or install the LCD cable.

The screen is damaged

Follow the guidance to replace the LCD panel.

A row of lights are damaged on the LED light board

Return to the factory for repair.

Black spot or black bar appears on the screen

LCD panel may be over heated. Let it cool or follow the guidance to replace the LCD panel.

The tension of the resin tank film is not strong enough

Replace with a new resin tank.

Problems with supports structures

Follow the guidance to manually add the supports

The model bottom is not pressed to the XY plane tightly

Check the first layer slice for any error

Wrinkles on the resin tank film

Replace with a new resin tank and increase the cooling time properly for the next print

Solid resin residue on the bottom of the build platform causes damage to the resin tank film

Replace with a new resin tank and clean the residual resin on the screen

Resin bottle not inserted into the right place

Clean up the residual resin according to the guidance and replace with a new resin bottle, make sure the bottle is inserted all the way in

The top vent hole of the resin bottle has not been pierced

Pierce either top hole of the resin bottle with the provided awl

Light-blocking tape is damaged

Replace with new tape, cut and cover any exposed area

Shaky Z axis

Adjust the tightness of the lead screw nut and the build platform holder according to the guide

There is leak from the liquid cooling system

Replace with new LCD cooling module or return to the factory for repair.

The bottom of the build platform and the LCD panel are not parallel

Adjust the build platform parallelism according to the tutorial video

Z-axis limit switch is dysfunctional.

Check if the micro switch cable is broken; return to the factory for repair if it is well connected

The peristaltic pump nut fell off

Install the nut according to the guidance

The peristaltic pump tube fell off or blocked

Install or replace the tube according to the guidance

The buckle of the peristaltic pump fell off

Install the tube according to the guidance

There is poor contact in the circuit board cable or program error

Reinsert the cable and restart

The circuit board has broken

Replace with a new circuit board according to the guidance

The fan cable has stuck or the bolt is over tightened

Remove the rear fan filter cover and check if there is any cable interference; adjust the tightness of the bolt accordingly

There are cured residues on Build Platform or in the Resin Tank

Inspect and clean the Build Platform and Resin Tank

High screen proportion of the print model (large section area)

Reduce motor speed in slice setting

Printer not on

plug it in an turn it on

If the printer is connected to a local WIFI, but not on the same WIFI as the computer, or the printer is not connected to the Internet

Connect the printer to the same LAN

Printer model selection does not match the printer

Change the printer type in the Desktop software

The first exposure is too short

Increase exposure time properly

The screen is working abnormally or damaged

Test the screen show logo function

Model data anomaly

Repair model

Improper printing setting

Optimize print parameters or contact UNIZ support

Support addition is unreasonable

Optimize support and parameters, or contact UNIZ support

Automatic pump material function is not on

Click 'on' in the printer control interface

Abnormal connection of liquid level sensor cable

Chect the cable

The Tank Film is damaged

Replace the resin tank film or resin tank

Old resin tank used (no seal)

Use new UDP Resin Tank with a seal

The resin bottle was not installed in the appropriate position

Reinstall the resin bottle to make sure it is in place

During the trial period of OL, RFID reads the exception

Upgrading the firmware version to 4.3 will remove the RFID limit for the trial period

Printer not connected

Configure printer networking

the film of the resin tank is crinkled

Tank Film overheated, change resin tank and increase the cooling time

Abnormal USB or WIFI connection

reconnect

the main program in the printer is not running

restart the printer

the cooling system leaks

Return to factory to fix

before printing, there is a cured resin residue on the bottom surface of the Build Platform, which leads to the breakage of the resin pool membrane

Replace the resin tank and clean the screen surface

The exposure of the first layer is too short

increase exposure time

The Build Platform roughness is not enough, the cured resin drop into resin tank

Polish the bottom surface of the Build Platform with the sandpaper attached to the printer and clean it

Insufficient adhesion between printed layers and following layers

increase the exposure time

Tank film and model adhesion too large

Replace the Resin Tank if there is any damage. Remove the Resin Tank and clean the surface of the LCD and the underside of the Resin Tank, wipe first with alcohol, then with a dry paper towel (note that you can only touch the glass portion of the screen and avoid pressing against the black tape).Increase cooling time appropriately

Choose zUDP resin in the material selection, and check UDP mode in the software's slice setting
