Diode laser power supply

Post by code_dude03 » Wed Feb 03, 2021 8:38 pm

Hi this is my first post here
im building a diode based engraver using this 405nm 500mw laser

https://www.ebay.co.uk/itm/405nm-500mW- ... %7Ciid%3A1

The laser comes with a 12v 2a psu just want to check could i use a higher current psu that could do the motors aswell (2x nema 17 @1.7a so probably a 5a supply for all 3 parts)
i know most components only draw as much as they need but some similar lasers with same board on ebay state supply <2a
