Power left to add LED to R3D

Hi gang,

I was wondering if there is any power left on the power supply to attach some LEDs, if it would be ok if I attach some LED to the power source, withour the risk to blow the whole thing

just a thought

Yes there is. If I ever get a chance I will show you mine. I bought some self adhesive led strips off of ebay. I put two 1 foot strip at the top of the housing and worked really well

 

Nice

But do yo know how many watts could I take from the power source to the LED's????
Just curious, I got a few LED strips and I was thinking about lighting up the whole printer hehehe

cheers

I know, but if the printer is using all power from the power source then you risk burning everything.
I was hoping the eople form Robo 3D would let us know so I can plan how much light would I be able to add.

But thank you anyway, your mod is neat.

cheers

-PC, have you attached LED's yet? I have put a few around in my ROBO with no problems.

I have replaced my warped Birch bed with a sheet of Polycarbonate and drilled 8 3mm holes in the side. Using 3mm red LED's I have wired them up in 2 sets of 4 LED's in series with 220ohm Resistors. I have also put 4 sets of 3 Ultra bright white LED's in the case in various places. I'm powering them off the PSU's 8Amp outlet. Total power draw for these LED's are about 330mA. There is ample supply to run these.

 

I can say that adding LEDs to the print head is going to be one of my first modifications to be sure. Having to grab a flash light to check the status of the print constantly is getting REALLY old REALLY fast!!! LOL

 

How did you wire in the dimmer?

Did you wire the LED's (and resistor) up to one of the 5v and ground pins on the microcontroller or tap into the power line for the print head so when the heads powered so are the LEDs?

 

Gotcha. That makes sense then...

My mod of adding LED lighting will have to wait... my printer died this afternoon. First the heated bed, and then the thermistor in the print head. {sigh} I didn't even have it 18 hours before it broke.

 

Was the first thing I did... no joy. Hit the RAMPS forums looking for ideas, that's where I saw the idea to swap the thermistor and heated bed connections to test that... the failure moved from the temp on the print head to the temp on the bed... that's why I suspected the thermistor in the print head died. As for the heated bed failure, multimeter shows no power to it. I disconnected the wires and checked for continuity and got good results there... so it looks like the RAMPS board is having problems and perhaps killed the thermistor in the process... but that's just totally guessing. {shrug} I'm no EE, but I know my way around arduino somewhat having build a few products with them already. I'm gonna try and see if the analog pin on the ultra works (the RAMPS site specs which pins those are) to see if the ultra is working to see if I can narrow down to it being one or the other...

 

I was a software tester for 20+ years and worked in embedded systems for a bit of that... while I'm no EE, I've been around them FAR too long to not have caught the desire to build circuits. When I discovered Arduino, it opened the world to me I'd always wanted to play in, but never had the time or ability to execute on. Every now and again them Italians get something right!!!

 

hey gang,
I really would like to hear from the R3D team about how many amps there still left on the PS, I would live to illuminate no only the extruder but the whole case.
