Be careful with the voltage control, I let you specify it in uv but it's converted to something else and there are only so many steps, so you won't necessarily get the exact amount you ask for. There are no steps between 1375000 and 1387500 so if I don't limit the max to 1387500 I don't know what it's going to jump to... Therefore I set the max to 1387500 for now.
