-I bought my Chinese Laser Cutter from a German vendor in 2014 in order get a Laser Class 1 system. A Class 1 laser is safe under all conditions of normal use. No need for any eye protection which increases the WAF (wife acceptance factor).

 After some trials I faced the common issue with MoshiDraw and the corresponding controller (MS10105 V4.5). One of the severe drawbacks of V4.5 is the missing link between controller board and laser power control. The laser power has to be set manually for each job.
 The next versions of the controller (V4.6) solves this bottleneck but it's still a closed system. And the Chinese MoshiDraw software is ugly...

 The new control panel
 I added a LED showing the laser activity and a button to trigger the laser. The rest is supported by I2C-Panel. The front design file (SVG) is attached.

 Therefore I decided to build a level shifter unit. With an op-amp (TLC271) the level at the optocoupler is judged at approx. 3V (with few 0.1V hysteresis). A following schmitt-trigger
