A basic introduction to the functionality of RAMPS 1.4 and how to. Required hardware: RAMPS 1.4 board. Hello all- This is my first day trying to hook up a reprap with RAMPS 1.4 I purchased assembled. I am trying to connect it to my Macbook Pro, via USB. It seems to want to connect as a USB modem, and Repsnapper will not connect to it. What am I missing? Thanks in advance! Edit: More info. I do get two green LED's on the ramps when trying to connect to the usb modem in system preferences, before it fails to connect. I also get some LED's when I press connect to printer in repsnapper. Any help would be appreciated, including suggestions on alternatives to repsnapper, and any way I can get this connected to my mac! Edited 1 time(s). Last edit at 07:06PM by xkylewrightx. My guess is you need to set the baud rate within Repsnapper. /dev/tty.usbmodem1a21 (you may get different last four digits and letters) is the correct device to connect to a RAMPS board from a Macintosh. I used to use Repsnapper, but have found Pronterface (for the latest and the pre-compiled version with Slic3r built in is at []) to be much more user-friendly. If I remember right, RAMPS 1.4, at least from Ultimachine, come with Sprinter firmware preinstalled, and it defaults to 115200 bps. Make sure your console program, either Pronterface or Repsnapper, matches this, or else you will not get a connection to the printer. What version of Mac OSX and what version of Arduino are you using? ![]() Do not install an FTDI driver, it's not needed for the Macintosh. Does anything show up in that terminal window? If it is gibberish, you probably still have the baud rate wrong. Select that in the lower right corner of the terminal window, and then hit enter in the text box at the top, or try sending M115. When you get back readable text you will know you have the correct baud rate setting. Now you should be able to upload the firmware. I'm using the latest version of mac leopard (10.7.3?) and version 1.0 of arduino. I havent installed a FTDI driver either. In Arduino I have the correct board selected (Mega 2560) and the correct port (dev/tty.usbmodem411). After launching the Serial Monitor nothing is showing in it. I can change the baud rate, but nothing shows up in the output. Tried sending M115 and still nothing showed up in output I am not sure if my ramps needs firmware, or if I messed it up by trying to put firmware on it. I could not get sprinter to compile but marlin seemed to compile okay, then had a bunch of timed out errors when uploading. ![]() Maybe I am missing a step that should be obvious? Will look further tomorrow, thanks for the help so far. I don't know any way to disable the physical rest on the Arduino, it has always worked for me. You can always unplug and reconnect the USB cable, that too will reset it (the Arduino gets its power via US. It sounds like you are able to push code to it, and when you do an upload it will also reset the board and install new code, so an equally valid thing to do now is just push Marlin to it.
