This project that I am working on the Engraving Machine has been a challenge to make everything to work together
The information on the internet is hit and miss for the most part
It is a good thing that I know how and what it takes to hook up most micro controllers yes each model is a little bit different but for the most part they are the same
The BIGGEST problem has been the markings on these Arduino Nano Controller boards not all are the same some board are marked better than others
You see how I have to hook up the laser and Nano Controller the pin output are not standardize which makes it more difficult to get things hooked up
Here is one example of what I am talking about if you look at the Nano Controller board you will see the connector that I have with the cable that runs to the laser controller this output for the PWM output is 0 to 5 volts the connector right next to one that has the cable this one is marked PWM output is not 0 to 5 volts it is 0 to 12 volts
I have another board that has two different output connectors one is marked TTL output and the other one is marked PWM output connector I have not tested what voltages these differently marked outputs and what voltages they are
The above is just the issues that I have been having to resolve with the laser I have even more issues to resolve with the spindle motor controller this is even more complex than the laser in that the output frequency of the Arduino Nano is 490 MHz and the spindle motor controller needs 0 to 10 MHz
The problem trying to get it work correctly and have complete control of the range is turning out to be a challenge I ordered a adjustable PWM controller that has frequently that can be adjustable as well so let see if this makes a difference in it respond to changing the PWM output duty cycle lets see if it works correctly the way I want it to work
Then the Y X Z axis are also challenging as well in finding all the parts that will work correctly together
I almost have all the parts for it together and let put this engraving machine together let hope I do not have any other issues that set me back again
