This is a set of 37 sensors ready to be connected up to a microcontroller, e.g. Arduino or RaspberryPi. A great package for Arduino experiments or as a basis for a larger project

This full upgrade kit includes every parts you need to upgrade CR-10 Standard into CR-10S.

• New main board support 2 new functions: resume printing after power off and filament detection.
• Dual Z-axis makes the 3D printer works more stably.
• Filament sensor will automatically stop the printer when filament runs out to avoid wasting of filaments and time.
• All these parts are from original manufacturer. Quality is guaranteed.

PLA, or Polylactic Acid, is a commonly used thermoplastic material that does not require the use of a heated print bed. Because of the lower melting temperatures and lack of warping, PLA filaments retain their color vibrancy and are a common choice for displays or small household prints.

• Does not require heated print bed. Can printe directly.
• Less warping, more flexible than ABS filament.
• Easy to print. Printing temperature is 180°C - 200°C.
• Environment-friendly, PLA material is biodegradable. No harm to human and environment.
