hi I followed the tutorial with my RAMPS 1.4 and instead of blinking constantly it blinked 2 time and goes of, but the arduino beneath had still a green light on. Do you know if its also right? Thanks for help
Hi I think you may be able to help me as I got ultimaker original but missing the 19 v power supply with 4 pin din output so I want to make it myself but I need the 4 pin polarity diagram, do you have it? Thank you
So what thickness does the Silicone Wiring have? Was thinking about getting 2mm^2 for heatbed mainboard pwr etc. and then 0.5mm^2 from the buck to the pi
Thank you for your question, SAAHIB. Roughly, you need nine heater-bed of 310*310mm beneath a 1000*1000mm bed. Assuming that each heater-bed requires 15A*12V power, the total power needed is 1,620W. So you can use three of 50A*12V SMPS. Each SMPS can support three heater-beds. And each heater-bed needs an external 'Power Expansion Module.'
A creative question, Rama. If you have 2 separate adapters, for example, one is 5A-12V and another is 15A-12V, you can use them for one RAMPS board. However, for this 310mm *310mm heated bed, you should use a 'power expansion module' as I mentioned below. And the bigger adapter should be connected to the power expansion module. And another small 12V adapter is needed for the RAMPS power terminal for the heated bed.
So if I am using mk2b which is 214 × 214 . Bcoz I m making prusa i3 clone with ramps 1.4, So, which supply should I use.??? 15 a 12 v ?? Thanx for your much informative replies♡♡

After watching 100+ vedios based on a diy 3d printer I cannot identify why a smps has 3 negative markings and 3 positive markings😭😭. Your vedio is too helpful but can you answer the above question 🤔🤔
Thank you for your comment, Rama. As you comment, a typical SMPS has 3 negative and 3 positive output terminals. It means you can supply DC voltage to 3 electronic devices or components at the same time because one electronic device should be connected to one negative and one positive DC terminal. I hope this answer is helpful to you.
But as marked in ramps 1.4 , it needs a 5 amp and 12 volt output and a 11 amp and 11 volt output. And you used a 30apm smps .ok, So, 5 amp + 11 amp= 16 amp or 192 watt . So why here you used 300 watt ones. Thanx for reply 😍
@@ramarastogi922 Good question, Rama. For this 'Atomic U300' 3d printer, I use a 310mm * 310mm heated bed. And this heated bed consumes 180 watts (15A * 12V). This 15A exceeds the maximum current that the RAMPS board's heated bed terminal can handle. So you should use a 'power expansion module'. And the minimum power supply requirement is 240 watts or 20A(15A + 5A). That is why I use 360-watt SMPS. The extra 120 watts is headroom for safety. I hope this answer is helpful to you.

Thank you for your question, Timo.
I use a 16AWG, 1.291mm, cable for the main power. And I use a 20AWG, 0.812mm, cable for the heated.
Hello, can you upload a video of how to connect with 3pin rocker switch?? Thank you~~
HI, Ban Ak! Thank you for your question. I found out a useful video on RUclips,

Should I use 2 different power supply like 1 of 12 volt and 5 amps
And 2nd . 12 volt and 10 amps or 15 amps???

@@MakeTogether 20 amps for what ??
🤔🤔
For that 11 amps terminal??
Or for both🤔🤔.
Power supply is the last topic and also the most confusing ones🙁🙁

Hi, I made it with a ramp 1.6 , it has an electrical input, where is the second input?
Thank you for your question, Meysam.
Ramps 1.6 seems to have only one power input.
@@MakeTogether Yes, but in some maps the input is between 12 v and 36 v, can 36 v be connected to it?
@@Imeytham I have not used it yet. But according to their diagram, input and output voltage ranges are from 12 to 36 volt.
