I just downloaded the OpenFL API to tweak some material parameters for nonstandard resins. It’s great! But I’m wondering what range of speed and power is available. That is, how fast and how high in power can I go? Presumably the laser can go up to 120mW, but if it does, could it damage the tank? Can I crank up the laser speed, and if so do I sacrifice precision? Thanks in advance! ---

In the Python OpenFL bindings, we [clamp laser power to 64 mW](https://github.com/Formlabs/OpenFL/blob/master/OpenFL/Printer.py#L58) as a safe bound. Increasing galvo scan speed will have an impact on print quality. In practice, we usually keep `xyfeedrate` below 2500 mm / sec; going higher will make the prints less accurate and (at very high speeds) may damage your galvos. ---
