Inventables Electronics Batch 1
ShapeOko kits purchased through Inventables come with a full set of electronics, which includes the following:
- Arduino Uno
- Power Supply
- Stepper Motors
- Emergency Stop
- Terminal Strip
- Cables and Connectors
The Arduino is the heart of the electronics. It contains an AVR Processor, a USB connector, and I/O pins. The Arduino comes with grbl already installed on board. grbl reads g-code that is sent over USB and translates it into movements for the stepper motors on the ShapeOKO. The particular version of grbl on the Arduino also comes pre-configured for the ShapeOKO, and should not require any tweaking to operate.
The GRBLShield plugs into the stop of the Arduino, and is what takes the signals grbl generates and drives the steppers. As shipped from Inventables, the shield has had the micro-stepping changed on the Z-axis driver to enable faster travel speeds.
The power supply provides 24 volts at 4.5 amps. Be careful with it. The connector that ships with the power supply comes with plugs on both ends. It needs to be modified ion order to plug into the GRBLShield.
