How to connect ramps1.4+arduino mega with Raspberry pi Hello can someone help me to connect a raspberry Pi on my printer? I have arduino mega+ramps 1.4 I like to use octoprint and I was wondering if this is possible! I also just bought this 3d scanner [www.achatzmediaserver.com] and I like to integrate into my printer! As I understand a separate power supply for Raspberry is needed though it would be interesting to see if this system is feasible and especially if I can make it as possible integrated into the machine! https://reprap.org/forum/read.php?219,559861,559861#msg-559861 Tue, 21 Jul 2026 12:52:39 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,559861,560771#msg-560771 Re: How to connect ramps1.4+arduino mega with Raspberry pi https://reprap.org/forum/read.php?219,559861,560771#msg-560771 This Video tells you exactly how to set up Octoprint.]]> gmckee RAMPS Electronics Sun, 20 Sep 2015 15:03:25 -0400 https://reprap.org/forum/read.php?219,559861,560601#msg-560601 Re: How to connect ramps1.4+arduino mega with Raspberry pi https://reprap.org/forum/read.php?219,559861,560601#msg-560601

You connect raspberry to arduino using an USB cable. Nothing Else.
You need a 5v power input for raspberry through it's mini USB port.
I need another power supply, or I can take the power from ramps??
You need a 5v wall-wart OR a step-Down to provide 5v to the Raspberry

The Rasberry can provide power to arduino through the USB plugs in the end of the Raspberry- Arduino only need like 0,2amps.

The Raspberry gets power through the mini-usb in the side-
The Rasberry connects to the Arduino through the "normal" USB-plugs (4 of them in Raspberyr Pi2) in the end of the Raspberry.

You do not want to power Raspberry in any way through the Ramps.

There is now 5V power on Ramps, it comes from arduino and is to weak for powering RasPI, too.
Wallwart 5V USB chargers are cheap, get one with the right USB-plug.
