How to adjust the lens of Mintion Beagle Camera?

This article is a step-by-step guideline that will help you adjust the lens of the Beagle camera quickly and correctly. The default lens focus distance is 20cm, and in this article, we will adjust the distance to 30cm in order to have a clearer video and better quality when we print with a large size model or have a longer distance in front of the model. The following steps are including printing the calibration chart and ruler, disassembling the camera and cables of IR-sensor & MIC, printing the holder and installation, adjusting the lens, and assembling back the camera.  

Print the Calibration Chart & Ruler

1. Download the lens calibration chart image and print with A4 paper if you have the inkjet printer. Please don't select the adaptive border when printing.   

2. Stick the calibration chart onto the straight wall and keep the whole paper flat, not in a wrinkle. 

3. Stick the ruler onto the desk and keep the ruler is with the right angle with the calibration chart. 

Disassemble the Case of Beagle Camera

  • 1. Use the screw driver to take off 4pcs of cross self-drilling screws on the back panel of the camera.

  • 2. Take off the IR-sensor and MIC slot cable.  (Please don't touch the camera lens, otherwise, you need to clean it with alcohol.) 

Print the Holder Bracket & Installation
