Maybe my file was from Marlin 1.0.2 (https://github.com/MarlinFirmware/Marlin/issues/1259)

Download the Original Marlin Firmware
Version 1.0.0 for the Scoovo X9H 3D Printer

I needed to use Arduino 1.0.5 or an older version to update the firmware, as later versions could not load the add-in needed to load the RAMBo board. Without this the LCD could not be loaded.

Note: Ardunio version 1.6.7 nightly build worked. I still had to load the RAMBo board driver/plug via the preferences popup though.

UltiMachine RAMBo Rev. 1.3L

This is RAMBo v1.3L. The RAMBo board is an all in one 3D printer motherboard. It is a full remix of our RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB. That is where it got the name RAMBo – (R)epRap (A)rduino-(M)ega-compatible (M)other (Bo)ard.

Major Features – 5 x integrated 1/16th microstep motor drivers, 5 PWM Mosfet outputs, 4 thermistor inputs, digital trimpot (no tiny knobs to tweak), SMPS supports hostless printing on power supply voltages from 10-24V DC, 3 independent fuse protected power rails, LUFA USB, high quality connectors, did I say hacker friendly …

RAMBo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware control of the digital trimpots and the microstep setting pins.

Please choose above if you prefer to receive a RAMBo assembled circuit board only, or if you require the entire kit. The circuit board will arrive pre-assembled, with all electronic components securely soldered to the PCB, ready for use. In the kit, you will receive the endstop switches/wire harnesses of your choice, two thermistor wire harnesses, plug connectors, USB cable, & we throw in gold connectors/headers for use on the motors & possible extra fan.

RAMBo Kit Includes:

(1) Pre-Assembled RAMBo PCB
(2) Crimped/housed thermistor wire harness, 914.4mm (36″) *thermistor not included*
(1) 6-pin pluggable terminal block (black)
(5) 2-pin pluggable terminal block (black)
(1) 1×2 positive latch housing & matching gold connectors
(6) 1×4 positive latch housings & matching gold connectors for crimping motor cables
(1) USB Cable, 1.828m (6′)
(3) Choice of endstop switch (Mechanical, Optical)
(1) Matching endstop harness set (Mechanical, Optical), pre-crimped/housed, 609.6mm (24″)

Designed and assembled in USA by UltiMachine.

Firmware / Hardware Information –
Recommended Power supply 12V-28V DC, 16A+.

A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE and set board to “Arduino Mega 2560”. There is also a Arduino plugin folder on github that exposes additional pins in the Arduino IDE.

Linux and Mac use CDC interface and have hardware driver built in.
Windows hardware driver: RAMBo_USBdriver.zip

Version 1.1 and later use 1/16 microstep drivers. Previous versions were 1/8th.RAMBO V1.3 MANUAL – VIEW HERE

NOTE: If purchasing this board as a replacement for one received in another distributor’s printer kit, please “Add a note to your order” (“notes” located in shopping cart view) prior to checkout regarding your printer’s name/version/distributor details. The controller may require some adjustments for printer compatibility. Thank you!

Distance = 22 * 2.03 = 44.66 mm
Steps per mm = 3200 / 44.66 ≈ 71.65 steps/mm

Move 100 mm with 71.65 steps/mm:
Steps = 100 * 71.65 = 7165 steps

With 71.649127:
Steps = 100 * 71.649127 = 7164.9127 ≈ 7165 steps
No difference in steps, showing 2 decimal places are often sufficient.

X/Y: 71.65 (microstep resolution ~14 µm).
