Firmware 1.16 calibration guide:

  1. Record current 1.15 settings, especially if you have any custom settings.
  2. Upgrade firmware to 1.16, refer settings to 1.15 IF you use any custom setting. However, keep X/Y size at 900.
  3. Check center using cross pattern. At the same time, make sure x/y galvo are set correctly, (pushed all the way in)
  4. Run calibration scan circle, ONLY match the outside 120x120mm circle. Ignore inner circle
  5. Print a cube on the outside to check how much the size is off
  6. Use x/y size to correct the difference.


  • 1.16
    • Compensate X/Y - This firmware helps correct X/Y distortions from galvo system.
      • This adjust X/Y for distortions. Since Galvo/laser setup only has distortion on Y-axis, adjustment to Y-axis is only needed.
      • Default value for Compensate X is 100
      • Default value for Compensate Y is 200
      • To get the best adjustment results, we recommend user to go through advanced calibration
  • 1.15
    • X / Y Size range increase from 400 to 1000.
      • So if you have a custom setting for either X Size or Y Size, multiply it by 2.5, and you will get the corresponding value in Firmware 1.15. For example, 360 in 1.14 is now 900. (see below for recommended settings) Each unit in X/Y Size represents 0.02mm change in print size.
    • Laser does not fire when user adjust the power value in the setting
    • User can now immediately cancel a print, and it will be followed by a peel action before raising the build plate to reduce peel force
  • 1.14
    • Calibration
    • Accuracy improvements
