|Original Rapide controller|
I had a Smoothieboard from a Kickstarter which I had intended to use for a CNC router project but I decided to repurpose it for upgrading the Rapide printer. The Smoothieware web site does have extensive information on making use of the Smoothieboard.
The printer has 5 stepper motors, of which two are used to drive the y-axis. I could have chosen to drive both from the same driver chip but I decided to drive each of the stepper motors from their own driver. To make the two stepper motors step together, a few links had to be soldered onto the Smoothieboard. In order to keep things as simple as possible, I decided to keep the order in which the stepper motors plug onto the controller board the same. I also soldered the same connectors to the Smoothieboard to avoid needing to recrimp new connectors onto the cables.

The HB-PWR cables was then connected to the PWR IN connector at the bottom centre of the board and JP28 was jumpered for the fan power. The heater bed HB-OUT was then connected to P2_7 connector and the head heater HE0 connected to P2_5.
The thermistor and endstops were plugged in as one would expect.

|Initial install of smoothieboard|
|Cables tidied a bit and heatsinks added|
The firmware install and upgrade is simply a case of putting the firmware.bin file in the root directory of a DOS formatted SDCARD. Instructions are available at: http://smoothieware.org/flashing-smoothie-firmware
A copy of my current config.txt is available here: config.txt
I do have my Smoothieboard plugged into my network so I have the ethernet enabled in my config.
