Machine: K40 with digital power readout
Board: C3D LB
Problem/ Question: After I received the K40, I installed the C3D laser board promptly and connected to my Mac. I got so excited I didn’t install the mA meter like I should have. After lasering a bunch of stuff, I came to my senses and decided to install the mA Meter into the HV return line to the LPS.
Installation went great. Until I turned the machine on…
The power display board had partially stopped working. None of the buttons or the display functioned, with the exception of the laser fire button, which still functioned admirably. The C3D operation still functioned great with the exception of the laser. Which did not work…fully. The laser does come on and stays on at about 4mA, barely noticeable burn. Stays on. Until I power cycle the machine. But it never does go up to operating power.
The test (text) button still fires the laser, and the test fire button on the display board does fire the laser. It also, however, maxes out the mA meter for while the laser is firing. The adjustment buttons no longer function on the power display.
I removed the meter and tried again with the same issues.
I ran the test in Laser not firing - new laserboard and got the same result with no continuity while running the test in both situations.
The red light does come on when it should be firing.
Any assistance as we quickly approach Christmas would be very helpful, thanks in advance!!!
