papaburs RAMBo v1.2 guide

[papabur]

I have been using the RAMPs v1.4 and Arduino Mega 2560 since I first got into 3d printing but I recently decided that there has to be something better out there..and I think I may have found it. After saving up 180$, I ordered a brand new RAMBo v1.2 board from ultimachine.com (Great company!). The kit includes: 3 mechanical endstops, 2 thermistor wire sets(i did not end up needing these), a 6-pin plug, Five 2-pin plugs, 1x4 housing/connectors(x6) and 1x2 housing/connectors(x1).
Heres a pic of the board:

First thing I did was mark all my wires, just to be safe and to make the install a bit quicker. Once I had the RAMBo board powered and plugged into my computer, it was time for the drivers, which are located here: https://github.com/ultimachine/RAMBo...no_1.x.x/rambo

It will most likely try to find them for you and when windows fails, select to find them yourself then direct it to the rambo/drivers folder.

You will also need the most current version of Marlin:

So now that your computer is picking up the rambo board and you have downloaded the correct firmware, time to make a few adjustments to the firmware before we upload it...
First change is the motherboard, change this to 301. Then you need to change your thermal settings to look like this:

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1
(Make sure to plug the heated bed thermistor into the T2 pins(http://makergear.wikidot.com/m2-electronics), unlike RAMPs which uses T1 pins)
