Power Supply Smoked
Posted: December 29th, 2018, 8:06 am
The other day while I was playing with the Raspberry Pi OctoPrint plugin OctoLapse.
I had turned on the UPS battery backup with the switch on the 3DP12 in the on position. Before I realized it.
The 3D Printers S-480-24 Power Supply started sparking and popping like a 4th of July fireworks display.
I quickly turned off everything and slowly started to diagnose exactly what had just exploded in the fiery display of sparks and smoke.
After diagnosing that only the 3D Printer had succumbed to the explosive electrical shower of sparks, smoke an fire.
It is now time to start the diagnostic and repair of my dead 3D Printer. I Quickly Unplugged the 3DP12 from it heat chamber home.
Took in into the work bench and quickly removed the original S-480-24 Power Supply. Writing down every wire color and location on the supply.
Then installing the backup Supply for my 3DP11 24volt upgrade into the 3DP12 3D Printer, connected all the wires according to my notes.
Now before turning on power to the 3D Printer a few tests, disconnecting the controller power lead I will test the Led's dimming controller circuit.
This is simply a LM317 variable 12v power supply circuit I designed for the 24 Volt supply to dim the 3D Printer frames led.
This is working as designed. Now unplug and reconnect the Controller supply power wire.
The raspberry pi seems to have survived, and is allowing me to send and receive data stored on the devices SDcard.
Connecting the 3DP12's Controller to a USB power source to see if the controller had been damaged by the S-480-24's little display of fire and smoke.
Luckily no damage had occurred to any of its components, and the Power input terminals do not have a shorted circuit.
Connecting the controller to my home made 0~30 volt 10 amp supply will adjust the voltage up slowly to see if the current spikes.
20.0 volts .08 amps this is good an means no shorts. All test to the controller says it was ready to be powered on.
So with all hand ready for the worst power switch to the on postilion and the printer is back to life.
Now for a small simple print which turned out fine and we at running again.
