FlashPrint Slicer software Otto is very well designed for 3D printing, the files that you had downloaded are property oriented and centered, so wont give you trouble if you follow this common parameters:. Recommended to use a FDM 3D printer with PLA material. No need supports or rafts at all. Resolution: 0.15mm. Fill density 20% For slicing and generating the g code for the machine free slicer software like or in our case FlashPrint that comes with the Finder 3D printer that we are using (If you are outsourcing the printing no need to worry about it) After printing you will need to clean a little bit the legs and feet areas that fix the motors.

This setup is ONLY needed for modules that don't come with the standard baud rate of 9600, how to know? Just try first the code and the APP, if the phone doesn't pair with Otto or respond to commands, then probably means your module is in a different baud rate so need to be configured The BT code has 115200 baud-rate so BT module must match that speed to be able to communicate with Arduino Nano via serial interface(UART).
For HC-05: 38400 or 115200 1. Upload the sketch HC05BTconfig.ino to your Nano first, then disconnect Nano from USB. Now connect BT to Arduino Nano as shown in diagram but do not connect VCC. TX - RX RX - TX VCC - 5V GND - GND 3.

Plug in the USB to Nano and then connect VCC so BT enters AT mode. LED on BT should start to blink slower, about once every 2 seconds. (If this doesn't work, try holding the button on BT module while connecting VCC). Open serial monitor in IDE, set baud-rate to 9600 and line ending to Both NL & CR. Type AT then press enter; (if everything is right, BT should respond with OK and then enter following commands: AT+NAME=Zowi 'setting the name' AT+PSWD=1234 'pairing password' AT+UART=115200,1,0 'baud rate' AT+POLAR=1,0 'enabling STATE pin to be used as reset for programming arduino over BT' Now go to the APP step If any problem check this instructable of how to Modify the HC-05 Bluetooth Module Defaults Using AT Commands For HC-06: 9600 or 115200 For HC-06 BT module things are a little simpler because module is always in AT command mode when not connected to anything.
But the downside is that HC-06 module cannot be used to upload sketches to Arduino because it doesn't have reset. For configuring the module 1. Upload this sketch HC06BTconfig.ino to your Nano 1.
Disconnect USB 2. Connect BT module to Arduino Nano like this: TX - RX RX - TX VCC - 5V GND - GND 3. Power on your Nano and after about 10-15 seconds everything should be finished and your BT should be configured (LED13 should start blinking).
If any problem check this instructable.
