Figured it out. Thermistor was hooked up to wrong terminal, should be T2 like the RAMPS (which is the third port on the RAMBo board, I was plugging it in the last)

Also checked configuration.h and have motherboard = 301. I'm thinking the Marlin firmware is missing some code for the heated bed, I copied this over from a previous Marlin I had running with RAMPS 1.4 but still no success.
#ifdef PIDTEMPBED
case 304: // M304
{
if(code_seen('P')) bedKp = code_value();
if(code_seen('I')) bedKi = code_value()*PID_dT;
if(code_se

RAMPS Electronics
Hello, sorry to ask another question, but I am wondering if anyone has set up a heated bed with a RAMBo board yet. All the firmware works the same except my heated bed is not yet working properly, I am using Marlin firmware and wondering if pin assignments change at all between RAMPS 1.4 and RAMBo
Thanks again,
Joe

I just replaced my RAMPS 1.4 with a new RAMBo board to allow more inputs for thermistors and fans. However, nothing is detected when I attach the USB drive, regardless of if the 12V power supply is on or off. It is not a driver problem yet, just the fact that the board won't power up. I'm using a voltmeter to try to debug but wondering if I am just missing something simple.
Thanks for your he

RAMPS Electronics
I am trying to add a fan to my RAMPS 1.4 board but thus far have been unsuccessful in getting any readings from a multimeter off of the D09 port. I have been using the command M106 SXXX to send values to the port, but nothing is changing. I have already uncommented the pin for the fan (23), is there anything else I need to do to enable this port?
Thanks,
Joe

I was using Pronterface successfully on my computer, then decided to learn how to use Arduino to learn how to control individual step motors and temperatures. After successfully interfacing with Arduino, I went back to Pronterface and it could no longer connect to the printer.
Any ideas for why this might be? Is there some configuration I need to run before switching back to Pronterface.
