Re: Rotary encoder on Unimat PC CNC


Thanks for a great tip. The iPhone 4 cam, was able to see a IR on a remote, but was unable to detect the Emco Sensor. However, using a D-link webcam, I was able to verify that at least the light source is function able on the sensor.

I will try to measure the sensor next.

The light from the sensor is in the near InfraRed range (IR) and is not visable by the naked eye. You may be able to "see" it using a digital video camera. That is how I check IR remotes to see if they are functioning.

I am trying to get a Emco Unimat CNC working. However, the rotary encoder does not seem to work. As I understand it is an optical sensor, and I measured it and it gets 5 volt from the controller card. However there is no visible light from the unit/sensor when connected and powered.

Maybe a dumb question but should the light be clearly visible?

The sensor seems to be roughly the same as on the 5CNC, photos of the sensor is available here:
