Asura by Peopoly

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. 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 STL file and measure the actual print value. The blocks on the print is designed to make it easier to measure. Each side starts 11, 21, 31, 41, 51, and 61

Record numbers for all 4 sides, X+, X-, Y+, Y- This will all makes sense in the next step

5. Open the calibration config file moai_calib-v2.acp in notepad or any text editor. You will see:

The Xval and Yval correspond to the measurements obtain in step 4.

To use your own data point. let's say your X+ 61 is measured at 62. This means the X+ side is supposed to be 61mm long but the actual print is 62mm long. To adjust for your print

- calculate the adjustment value. In this case, it is 61 + (62-61)/2 = 61.5

On the row Xval 61 60.6. Change it to Xval 61 61.5

Save the file to a new name. And select it when you use Asura to slice.
