Hi John, Pretty much. I have been researching big time. Here is one site will question and answers are found Endurance lasers. We produce and sell powerful and efficient diode lasers (solid state). Useful attachment to any 3D printer or CNC machine. And I also found this site. Endurance lasers. We produce and sell powerful and efficient diode lasers (solid state). Useful attachment to any 3D printer or CNC machine. This site describes using a "controller" much like you described. I also found out the 5dcv for the TTL+ can also be 12dcv. The 12DCV 5A powers the fans and laser. The TTL+ can be connected to the PWM output and attach that to the TTL+ line for intensity control. It described has being the spindle. Hopefully, the power supply will be here soon and I can try it out. Thank you for your help and interest.
