You won't break anything. The motors will naturally get hot, but you should still be able to touch them. If not, then it's running on too many amps. You can hear the motor's skipping steps if the amps are too low.

You can increase each of the 3 knobs (potentiometers) to full. On your CNC software (Mach3?) you can set the acceleration and feed rate. This will increase or decrease the amps to compensate -- so it can be controlled by software. Again -- just monitor the heat.

If you are going to be running it for a few hours, it wouldn't be a bad thing to put a small fan to the enclosure. Just make sure things don't get too hot. :)

If you really want to get more torque from the driver board, I will suggest you change to a powersupply with higher voltage. I didn't publish that the driver can support up to 24V, the reason is that it is enough for driving our machine, and also it will generate much less heat during the operation. But definitely you can do it if you need it.

The chip on the driver will only support up to 1.5A/phase stepper motor, so keep that in mind. By adjusting the max output current, it will not blow the anything up, just don't let the motor overheated, as long as you can still touch the motor with hand, it is ok.

Any advise on how to measure the motor current with a multimeter?
