Print List Tool List System List

Leveling

1. Remove the resin tank, lock the screw knob  ⑤  of the build plate, and then loosen the 4 fixing screws ( ①②③④ ) of the build plate until the build plate can move freely. (See Picture 1)

2. Place a leveling card between the build plate and the LCD screen, then click “Move Z axis to zero” (See Picture 2). After the printer stops moving, press the top of the build plate with one hand, and lock the 4 fixing screws ( ①②③④ ) with the other hand. (See Picture 3)

3. Pull the leveling card. If you find there is a slight resistance during this process, you can go directly to step 5. (Note: If there is no resistance when pulling out the leveling card, please click the Z-axis “down” button (in steps of 0.1mm) until there is a slight resistance to pull the leveling card. If there is too much resistance or the leveling card cannot move, please click the Z-axis “up” button (in steps of 0.1mm) until there is slight resistance to pull the leveling card.) (See Picture 4)

4. After completing the above operations, back to the previous menu, and click “Set Z=0”, then a confirmation pop-up window will appear in the interface, click “Confirm” to complete the setting.
   At this time, the current Z-axis position is reset to the new initial height of the first printing layer. (See Picture 5)

5. Click back to the “Manual” page, and click the Z-axis “up” button to raise the Z-axis by a certain distance. (about 100mm) (See Picture 6)

6. Take away the leveling card, and click the “Tool” – “Exposure” – “Text” buttons to test the LCD screen and LED light source. If the LCD can display “ELEGOO TECHNOLOGY www.elegoo.com“, then the 3D printer works perfectly. At this time, the leveling is completed, install the resin tank and ready for printing. (See Picture 7)

Test Printing

1. Model Printing
   Plug the USB air purifier into the USB port (See Picture 8), then slowly add resin to the resin tank (do not exceed the MAX line height).
   Cover the printer and then insert the U disk into the printer and select the pre-sliced test model for printing.

2. Model Processing
   After the printing is completed, wait until the resin on the build plate stops dripping, then loosen the screw knob of the build plate to remove it, and remove the model with a scraper. You can use ELEGOO’s cleaning and curing machine to post-process the model. (See Picture 9)

Software Installation and Setup

The printer can install and use Chitu Box and Voxeldance Tango slicing software in the USB flash drive, here we take Chitu Box as an example.

   Click “Parameter Settings” and select ELEGOO Mars 4 Ultra as your default printer. (See Picture 10) 3.2 Build Volume
   You don’t need to change the default parameters (See Picture 11), and X indicates the maximum print size in the X-axis direction, and so on.
   3.3 Resin Parameter (See Picture 12)
   Resin Density: 1.1g/ml
   Resin Cost: You can input the real price of the resin you purchased, and the slicing software can calculate the resin costs for each model you print. 3.4 Parameters (See Picture 12)
   Layer Height: The thickness of each printed layer, the recommended height is 0.05mm, but you can set it from 0.01-0.2mm. The higher thickness you set, the longer the exposure time will be required for each layer.
   Bottom Layer Count: The set number of initial printing layers. If the number of bottom layers is n, the exposure time of the first n layers is the exposure time of the bottom layer. The default setting is 2.
   Exposure Time: The exposure time for normal printing layers. The default exposure time is 2.5s, the thicker the print layer setting, the longer the time required.
   Bottom Exposure Time: The setting of bottom layer exposure time. Properly increasing the bottom layer exposure time can help to increase the bonding strength between the printed model and the printing platform, and the default setting is 32s.
   Transition Layers: The number of transition layers after the bottom layers for a tighter bonding between layers. Except for the exposure time, other parameters of the transition layer are the same as the normal layer.
   Transition Type: Set the transition type of exposure time when transitioning from bottom layers to normal layers, the default is linear transition.
   Wait After Cure:The time difference between the end of the exposure and the start of the build platform moving away from the exposure surface, the default setting is 0 seconds.
   The Quiescent Time After Lifting: The time difference between the build platform starts to standstill and starts to return after the build platform lift, the default setting is 0 seconds.
   The Quiescent Time After Retract: After the build platform moves to the printing surface, the time difference between the build platform starting to stationary and starting to exposure, the default setting is 0.5 seconds.
   Bottom Lifting Distance: During the bottom printing process, the distance that the build platform moves away from the printing surface each time, the default setting is 2+3mm.
   Lifting Distance: In the normal layer printing process, the distance that the build platform moves away from the printing surface each time, the default setting is 2+3mm.
   Bottom Retract Distance: During the bottom printing process, the retract distance of the build platform, please do not change if not necessary.
   Retract Distance: In the normal layer printing process, the retract distance of the build platform, please do not change if not necessary.
   Bottom Lift Speed: During the bottom printing process, the moving speed of the build platform away from the printing surface each time, the default setting is 75+230mm/min.
   Lifting Speed: In the normal layer printing process, the moving speed of the build platform away from the printing surface each time; the default setting is 75+230mm/min.
   Bottom Retract Speed: During the bottom printing process, the moving speed of the build platform is close to the printing surface; the default setting is 230+75mm/min.
   Retract Speed: In the normal layer printing, the moving speed of the build platform is close to the printing surface; the default setting is 230+75mm/min.
   Matching resin mode: The machineis preset with three slice parameter modes with different speeds for resin printing. According to the resin and printing speed requirements, choose appropriate printing modes. The “Standard Resin_Normal Speed” mode is selected by default.

Machine Maintenance

• Please do not use sharp or pointy tools to scrape the resin tank to avoid damaging the release liner film.
• Please clean up the resin tank before changing the resin to another color.
• Before and after printing, clean the build plate with paper towels or alcohol to ensure that there are no bumps or burrs on the build plate.
• Before each printing, daily check the exterior of the machine and all mechanical parts for any obvious damage, defects, or abnormalities.
• Try to keep the printing environment at 25-30 degrees Celsius when printing, and ventilate the printing room as much as possible to facilitate heat dissipation of the machine and resin odor volatilization.
• If the Z-axis keeps making friction noise, please add some lubricant to the lead screw. Please check and apply lubricant grease at least every 2-3 months, and increase the frequency of application as the printing frequency increases.
• If you don’t use the printer in the next 48 hours, please pour the remaining resin from the resin tank back into the resin bottle and seal it well. If there is any residue, please use a filter to filter it out.
• Check the condition of the release film before each printing, and observe whether the release film is loose, whether there are scratches or severe whitening on the surface, and if so, replace it in time. The release film is a vulnerable part, please replace it at least once every 1-2 months, and increase the replacement frequency as the printing frequency increases.
• Please be careful when removing the printing platform to prevent damaging the LCD screen.
• The service life of the screen is about 2000+ hours and will decrease with increasing printing frequency. Do a good job of daily screen cleaning, and unplug the machine in time after printing.
• If there is a screen exposure problem or service life has seriously affected the print quality, please replace the screen in time.
