Hi, also had a question about the pots. This is way ahead of itself but I saw this yesterday. The one for rpm can easily be a pot as it is not critical and I just sweep it the range I want. The bar width and length are a small range and should stay set at an exact number. You may remember I inquired about using an encoder in the past and now I see a 4131-103 digital pot. I wonder if it would be an easy way to do what I want or is there another way to input the numbers for those settings. To be honest I have just been writing to the code each time I need to change it!!
