I just purchased a more powerful 2.5W laser from Banggood to replace the 0.5W laser that I purchased the Eleksmaker with. Just now realized that the new one came without the TTL/PWM controller. Do you think it's possible to take the controller from the 0.5W laser which works with EleksDraw and use it with the new Laser? Or should I return it and buy the one with the TTL/PWM controller? Thanks.
