Yes, you don’t want to power the laser with 26ga. In fact, I don’t think you want to power it with 22ga either. I’m using 18ga and it runs through the 4 pin xlr connector you see in the picture. I was originally going to use a regular 4 pin molex – like the power for hard drives and stuff in a computer. Anything that can take 18ga or larger should be fine. That same plug will be used to power the heater when I put an extruder on my MPCNC.
