Slow heating

Ok, so here recently I noticed that my soldering iron would not get hot enough for the solder to stick to the tip so I thought my iron was bad. I buy a new one a few days later and it works fine until about 8 PM and then it starts doing the same thing. I have been rebuilding my 3D printer and redoing a lot of the wiring to clean it up and was able to use my soldering iron all day again until around 8 PM. Now I have my printer all back together and was going to run some test parts and noticed that my hotend will not get over 150c. I checked the outlet and am getting 122v per my multimeter.

What would cause this? I don’t know a lot about electricity so this has me baffled.

I also checked the power to the smoothieboard and it is at 12.11v

Figured out the problem with the hot end. Some how I had uncommented the “temperature_control.hotend.max_pwm” line.

Now here is the really strange part. I decided to plug my soldering iron into my computers UPS and it works great. Plug it in to the wall, same socket that the UPS is plugged into and it will not get hot enough.
Could this be a bad power issue and the cause of all the issues I have had with the smoothieboard I have?
