MakerBot BotStep17 REV E

The BotStep17 plugs into the MightyBoard to control the stepper motors on your MakerBot Replicator 1, 2, and 2X desktop 3D printers.

These little boards can blow from time to time with smoke and a loud crack noise.

There are 4 on a single extruding Makerbot Replicator 1 or 2 (X-axis, Y-axis, Z-axis, E-axis [for the extruder]), and 5 on the Replicator 2X and Twin Replicator 1.

There may be no physical evidence of a blown bot step on the board. When blown they can fade a screen, cause lines through a screen, and affect motor movement.

Before testing or installing, take a picture of the motherboard to make sure you get the orientation correct when you reinstall. If you suspect one has blown it is easy to test:

  1. Remove them one by one and turn the machine back on. Do not replace them until the end as there could be more than one that is blown.
  2. When you get to the point that the machine starts up properly, begin replacing the bot steps one at a time to see which ones are blown.
  3. Replace any bad BotSteps with new ones

If it is affecting movement, but not the screen etc, try swapping the Z-axis with the one related to the bad movement. Usually the X-axis as it works the hardest. If the problem resolves in the X direction, for example, you know that bot step needed replacing.

FTDI to USB cable

The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this FTDI cable are configured to operate at 5V.

The FTDI cable is designed around an FT232RQ, which is housed in a USB A connector. The other side of the cable is terminated with a 0.1" pitch, 6-pin connector with the following pinout: RTS, RX, TX, 5V, CTS, GND (RTS is the green cable and GND is black).

This cable has the same pinout and functionality as our FTDI Basic Breakout board; you can use it to program your Arduino ProPro Mini and Lilypad. For use with those boards, align the black and green wires of the FTDI cable with the 'BLK' and 'GRN' labels on the PCB.

There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators, but requires a Mini-B cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.

Sparkfun FlexiForce Pressure Sensor - 25lbs (1" area)

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor's resistance. Pressing hard, the resistance changes from infinite to ~50k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.

The overall length is about 2.25". The sensor comes with a 0.1" spaced, reinforced, breadboard friendly connector.

This sensor ranges from 0 to 25lbs of pressure.

9DOF-Razor1MO-Sparkfun

The SparkFun 9DoF Razor IMU M0 combines a SAMD21 microprocessor with an MPU-9250 9DoF (9 Degrees of Freedom) sensor to create a tiny, reprogrammable, multipurpose IMU (Inertial Measurement Unit). It can be programmed to monitor and log motion, transmit Euler angles over a serial port or even act as a step-counting pedometer.

The 9DoF Razor’s MPU-9250 features three 3-axis sensors---an accelerometer, gyroscope and magnetometer---that give it the ability to sense linear acceleration, angular rotation velocity and magnetic field vectors. The onboard microprocessor, Atmel’s SAMD21, is an Arduino-compatible, 32-bit ARM Cortex-M0+ microcontroller also featured on the Arduino Zero and SAMD21 Mini Breakout boards.

Sparkfun elastolite inverter

The INV133 is a simple and easy to use electroluminescent inverter from ELastoLite® that will allow you to drive any EL panel or panels with an area greater than 8in2 (and less than 20in2). The INV133 charges at 3.7V with a 1100mAh current thanks to the mini USB rechargeable Li-Poly battery enclosed in the inverter. All you need to do to start using the INV133 is simply plug in any 4-pin 1mm spaced connector or one of the ELastoLite® over-molded connectors, press a button, and get glowing!

ELastoLite® is a waterproof electroluminescent lamp line that allows you to apply light to any article of clothing or project. Thanks to a 3-dimensional, elastomeric, membranous polymer thick film, this EL line can be applied to almost any surface with no loss to flexibility and movement.

EL Escudos Board

The SparkFun EL Escudo Dos is an Arduino shield for controlling up to eight strands of electroluminescent wire. EL wire is flexible plastic cord that glows brightly when high-voltage AC is applied to it. It's available in numerous colors (see the related products below), runs cool, and requires very little current, but can be difficult to work with because of the high-voltage requirements. The El Escudo Dos contains circuitry to safely switch high-voltage AC on and off, allowing you to create animated displays or whatever else your imagination can come up with.

In addition to this shield, you will need Arduino headers (see the related products below), an inverter (a component that generates the high-voltage AC needed by EL wire), and the EL wire itself. SparkFun carries two inverters, a 3V-input version that can drive a few feet of EL wire, and a 12V-input version capable of driving dozens of feet of EL wire. Choose the one appropriate to your power source and driving requirements. The shield's built-in regulator comes preset to 3.3V, but can be set to any voltage by changing two resistors, or bypassed with a solder jumper to send the Arduino's RAW voltage directly to the inverter (perfect for 12V setups!).

Sparkfun Micro OLED Breakout

The SparkFun Micro OLED Breakout Board breaks out a small monochrome, blue-on-black OLED. It’s "micro", but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next Arduino project, displaying diagnostic information without resorting to serial output, and teaching a little game theory while creating a fun, Arduino-based video game. Most important of all, though, is the Micro OLED is easy to control over either an SPI or I2C interface.

You may be asking yourself, "Why does this board look so familiar?" Yes, this is essentially a MicroView without the Arduino portion. We understand that sometimes you just need a breakout, an open door for you to explore the possibilities of a super small OLED screen. Speaking of, the screen on this breakout is only 64 pixels wide and 48 pixels tall, measuring 0.66" across.

In total, the Micro OLED Breakout provides access to 16 of the OLED’s pins. Fortunately, though, you’ll only need about half of them to make the display work. The top row of pins (GND-CS) breaks out everything you’d need to interface with the OLED over an SPI or I2C interface. The pins on the bottom (D7-vB) are mostly only used if you need to control the display over a parallel interface. This board operates at 3.3V with a current of 10mA (20mA max).

Sparkfun GPS shield+header+GPS module

This is the SparkFun GPS Shield Kit, a great launch pad for anyone looking to get into the world of GPS. This little kit includes our GPS Shield, an EM-506 GPS Receiver with interface cable, and a set of R3 headers to solder onto the shield. Adding GPS to your Arduino has never been easier. Multiple GPS receivers attach easily to the shield, and with the example sketch (check below), you will be able to locate your exact position within a few meters. Here's where we are. GPS also gives you amazingly accurate time!

A connector for the popular EM-506 GPS receiver is populated on the board, and footprints for EM-408 and EB-85A connectors are also made available (connectors are not included and can be found below in the related items). The regular GPS pins (RX, TX, PPS, etc.) are also broken out to a 10-pin 0.1" pitch header, and a small prototyping area is also provided.

The DLINE/UART switch switches the GPS module's input/output between Arduino's standard TX/RX pins or any digital pins on the Arduino (default setting uses pins 3 and 2 connected to TX and RX, respectively). The DLINE/UART switch must be set to DLINE in order to upload code through the Arduino IDE.

The shield also includes the footprint for a 12mm coin cell battery holder to provide battery backup to the optional EB-85A GPS module.An ON/OFF switch is included which controls power to the GPS module. Additionally, the Arduino reset switch is also brought out.
