Hi All,
I've got two rulers for my lathe from aliexpress. Like this:![[Image: 201707291448365329.jpg]](http://www.shahemeasuring.com/UpLoadImage/BigImages/201707291448365329.jpg)
This are new ones with 0.01 mm accuracy.
Then I've got TouchDro Adapter Board with Micro-B Connector and tried to connect it with scales. System did not work and I tried to explore scale connector pinout. Usually USB pinout is 1- VCC, 2 and 3 - signal, 4 - GND. Scale pinout is differ and id 1-GND, 2-3,2V and 3 and 4 - signal. I've cut USB cable and connected wires accordingly pinouts above. Now I have this:
Any ideas?
Thanks
