Pictures are missing. Also, I upgraded your account so you can post multiple pictures. Please post pictures of the laser power supply and of the control board.
If you haven’t yet read New to K40: Start Here it has information that’s useful even though you aren’t actually new to K40, including Where can I find K40 replacement parts? which we’d be happy to improve with more detailed information.
The good news is that it’s very unlikely that it’s important whether the new Laser Power Supply looks like the old Laser Power Supply.
