Hello Forum! I have two very quick questions, and one medium length question. I have been trying to build a CO2 laser, and have had trouble getting the signal to activate the laser power supply. So I'm scrapping everything I have done and starting over. So I'm asking opinions on the following two questions: 1. Which controller is more suited for a CO2 laser, BlackBox or xPro V4? (I'll be using UGS and GRBL) 2. Which Meanwell Power Supply, 12V/29A or 24V? (I know it sounds like a dumb question, but I'm really not sure what power I need to run the LPS, motors, etc.) Also, any other advice on using these controllers and Power Supplies (other than the obvious... BE CAREFUL!!!) I want to buy this immediately so I can start on this build and need to get moving on it, so your quick response is MUCH appreciated!!!
