I already purchased my hot end and got a 12V E3dV6. I choose the 12volt as the RAMPS board was 12v. I checked the build requirements and see 24V. Can I just go the 12V route? I only see the fans (from amazon) that would need to be changed. The SSR looks good.
the main difference is your motors will run much smoother at 24v but other then that you would be fine. The e3d change over is just as easy, a 24v heater and fan. Personally, 24v is worth the effort.
I did 12v I think it will be okay. Still waiting on smoothieboard (ordered last month) to see how it runs though.
I certainly prefer 24v now.
You can just get a 40W heater and a 3010 fan for 24V from ali/ebay, doesn’t cost a lot.
@Daniel_F , it’s not quite as simple as that. You missed the part where his RAMPS board has 12v rated caps. I’m betting they’re also surface-mount, which means replacing them is practically impossible as well.
If he’s got through-hole caps on his RAMPS board, he can replace them with higher rated caps and some small modification though.
Ups. You’re right @ThantiK , didn’t think about that. Depends on the board, some have caps with 16v some with 35v. I got one with 35V, but I had to ask for the voltage rating of the caps. You also need to remove a diode. Arduino needs seperste power.I Then replaced the fuses with automotive fuses. The quality of cheap ramps 1.4 ($7.5) is not the best but mine works for 6 months now.
And of coarse the PSU also needs to be 24V.
Also, check the thermal fuse if you haven’t already replaced it with a normal fuse. I understand cheap RAMPS are built with 16V fuses.
Oh when I read it, it didn’t sound like he had a board yet. That changes things I guess
