RAMPS 1.4 with Mega ADK Hi I'm trying to build my first reprap printer and I'm planning to use a RAMPS electronic. In order to keep the door open to the ability of controlling my printer with an android device, I would like to change the Mega2560 with a MegaADK. I can find some clues about this topic, but no details: - On RAMPS page I read about a change QuoteServo1 connector moved to pin 11 to free 7 for ADK - I read over Ultimachine about a complete upgrade to Mega ADK, but no details. Do someone use a RAMPS with a MegaADK board? Where can I find proper firmware/hacks? Will other RAMPS optional SDramps or LCD/SD) be compatible with ADK board? Thanks in advance. https://reprap.org/forum/read.php?219,286799,286799#msg-286799 Tue, 16 Jun 2026 20:42:28 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,286799,287666#msg-287666 Re: RAMPS 1.4 with Mega ADK https://reprap.org/forum/read.php?219,286799,287666#msg-287666 Rebecca got my point of view: with a usb-host capable ramps, I can use every cheap android device. In my mind (not sure at all, need to verify), the adk firmware do things to connect to the device, then the normal printer firmware start without modification or added load.
I hope to be able to replace the LCD/SD extension for ramps with an android touch screen device and print a file stored here, without a PC or a SD (thanks to WiFi and a file server).]]> paciotti RAMPS Electronics Wed, 01 Jan 2014 17:44:31 -0500 https://reprap.org/forum/read.php?219,286799,287643#msg-287643 Re: RAMPS 1.4 with Mega ADK https://reprap.org/forum/read.php?219,286799,287643#msg-287643 uncle_bob RAMPS Electronics Wed, 01 Jan 2014 16:25:58 -0500 https://reprap.org/forum/read.php?219,286799,287028#msg-287028 Re: RAMPS 1.4 with Mega ADK https://reprap.org/forum/read.php?219,286799,287028#msg-287028 which end takes the role of USB host, and as the Mega ADK uses a separate USB chip over SPI to do this, it probably doesn't cause significant CPU load; however, the firmware would need to be changed to read from this interface instead of the normal USB interface.

As an easier alternative, the Android OS does also support normal USB, but not all Android hardware does, and battery life could be a problem.]]> rebecca.palmer RAMPS Electronics Tue, 31 Dec 2013 05:00:38 -0500 https://reprap.org/forum/read.php?219,286799,286860#msg-286860 Re: RAMPS 1.4 with Mega ADK https://reprap.org/forum/read.php?219,286799,286860#msg-286860

Next layer to the onion is the Mega CPU it's self. We aren't causing them to go up in smoke from over work, but we push pretty hard. Dropping something else in on top of the firmware would have to be done with care. A lot depends on which printer you are running and how fast you want to run it.]]> uncle_bob RAMPS Electronics Mon, 30 Dec 2013 17:00:02 -0500 https://reprap.org/forum/read.php?219,286799,286799#msg-286799 RAMPS 1.4 with Mega ADK https://reprap.org/forum/read.php?219,286799,286799#msg-286799 I'm trying to build my first reprap printer and I'm planning to use a RAMPS electronic.
