Asura is a 3D printing preparation software designed to that simplifies the process of preparing for resin-based 3D printing. It has both features specific to Moai SLA printer as well as for general resin 3D printing.

Main features:

• Import / Export STL files
• Adding Support and base (Automatically / Manual Addition)
• Scale and Rotate Models
• Slice Model to GCode (to print on Moai)
• Distortion Adjustment (Moai only / Gcode only)
• Lightning Fast Processing Speed
• Save/Load Projects
• Undo
• Z-axis cross-section view.

Distortion Adjustment function:

Asura 2.1 updates the distortion adjustment to more data points to cover asymmetrical distortion and prepare for Moai 200.

Depending on your applications, you may not need to adjust if dimensional accuracy is not very important. If you do, here are two ways you can utilize Asura 2.1's calibration feature.

General Adjustment.

You can simply select the default adjustment profile moai_calib-v2 as seen here in the export menu:

User can either select none or the included default profile moai_calib1. *Adjustment is only effective when exporting to GCODE

For most users, this would be enough to reduce distortion at the edge to under less than 1%. To make the best use of the moai_calib-v2.acp. We recommend that your printer is set up this way:

• During laser scanning calibration, only match the other circle
• And do not make use of the firmware x/y size to adjust the print size. Keep X/Y Size at the default value of 900

Since there are build differences between each Moai, this is will minimize some of the deviations. You may not see improvement if your Moai has different calibration than the printer we used to create this general profile. In case you want even high accuracy, use the custom approach

Custom Calibration Profile

This is for those who want to minimize size variance by using custom calibration profiles.

1. Download Calibration Print STL here

2. Load the STL into Asura (or Cura). Make sure it is centered by pressing center. X+ (Positive X Value) is back of the printer and X- (Negative X Value) is the side closest to the door.

3. Make sure your printer's laser is centered and scanning calibrated using Advance Moai calibration guide.

4. Print the above STL file with calibration set to NONE during slicing and measure the actual print value. The blocks on the print are designed to make it easier to measure. Each side starts 11, 21, 31, 41, 51, and 61

Export the file to your computer and then load it on the SD card for the printer within the gcode folder

Put the SD card back in the printer, reboot and print the gcode file you just created.

Remove the build plate with the print attached. Clean the resin off, but leave the print attached to the build plate. Do not try to cure it at this point. This is unnecessary for the calibration procedure.

Measure the actual print as shown and record the values. The blocks on the print are designed to make it easy to measure. Each axis (X+, X-, Y+, Y-) has 11, 21, 31, 41, 51, and 61mm dimensions.

5.

Make a copy of one of the calibration configuration files from the Asura “calib” folder with the extension .acp. Rename it to “mycalibration.acp” and save it back into the Asura “calib” folder.

Open the file you created with notepad or another simple text editor that does not modify or add data. Do not use a word processor like Word etc. unless you know how to export it as a simple text file with no formatting.

The Xval and Yval correspond to the measurements obtained in step 8. The first number in each line is the target value and is never changed, the second number is the correction factor.

To use your own data points. Enter the values you measured in step 8 as the second number in each line.

For example: If you measured -61.25 when you measured the longest part of X-, then you would change the row “Xval -61 60.6” to “Xval -61 -61.25

Once you have changed all the second numbers in each line to what you measured from the test print, then save the calibration file.

Now, print another one of the asura-calib-print-Moai.stl using your new calibration. Follow the same steps as before except when you select the “Export” Icon. Select the Calibration “mycalibration”. This should apply your correction values to the gcode export and your next print should measure out very close to the targets.
