Yes, cause 1:2 , 1:3 or whatever seems not to reflect reality , misleads the mind. The reality is that 16t is the smallest one and geared 1:3 means 48t for the second one which is in fact 75.25mm in diameter and at 100mm separated center from center they have only 6t in mesh. So imagine the inertia if from steel. Even from aluminum.
I assume you will be using servos. So the encoder count + ballscrew pitch will dictate your gearing, as it will determine resolution, max speed of the machine.
No, it will be a problem. Its not only the time, the faster it cures the more heat generates, the more it distorts. Whats the problem with the weather in UK? humidity is not a problem if its not raining directly on it. And where i live its much more humid.
