Control Board
The Odin One uses the SainSmart 2in1 Printer control board, this board can be purchased directly from SainSmart. This is a very capable board and combines the circuitry of the Arduino Mega 2560 R3 with that of the RAMPS 1.4. The 2in1 board solves several critical issues present in the RAMPS 1.4, in general the RAMPS is prone to heating issues and since it's produced by a wide range of manufacturers commonly contains substandard components.
SainSmart solved this issue by using high quality components while also consolidating the combo onto a single board. The board is large enough to disburse heat well while minimizing its overall footprint.
Key Improvements
- Natively supports full 1/32 Micro-stepping
- 12/24v Compatible
- Current to heat bed MOSFET reduced to solve failure issue found on RAMPS 1.4
- High quality fabrication and components
- High quality wire terminals
Board Configuration
The control board is well labeled so the connection of components can be done with relative ease. Always verify polarity when working with the controller to avoid damage (the extruder heater and thermistors are polarity neutral).
Installing Drivers
When installing DRV8825 stepper drivers be aware that the correct orientation has the potentiometer facing the main power in.
To correctly configure micro-stepping, you must place jumpers on the pins found in the "jumper banks" the correct jumper configuration is as follows:
| MS1 | MS2 | MS3 | Step |
|---|---|---|---|
| NO | NO | NO | Full Step |
| NO | YES | NO | 1/4 Step |
| YES | YES | NO | 1/8 Step |
| NO | NO | YES | 1/16 Step |
| YES | YES | YES | 1/32 Step |
Note: MS1 is the pin set closest to the metal cylindrical component
The Odin One's micro-step configuration for each axis is as follows:
| X | Y | Z | E |
|---|---|---|---|
| 1/32 | 1/32 | 1/32 | 1/16 |
Note:
The steps for the extruder were reduced when auto bed level was implemented, there was no noticeable benefit to running the additional micro-steps. With the additional z movements created during z correction tramming it made sense to reduce the micro-steps on the extruder.
Some Notes
Although this board is very capable and well built, the SainSmart customer service is notoriously poor. Keep this in mind while working with the board, and while dealing with SainSmart. This board can be purchased from Amazon with a 2 year replacement warranty if this is a concern.
