New Part Day: Smoothie For RAMPS

When it comes to 3D printer controllers, there are two main schools of thought. The first group is RAMPS or RAMBo which are respectively a 3D printer controller ‘shield’ for the Arduino Mega and a stand-alone controller board. These boards have been the standard for DIY 3D printers for a very long time, and are the brains for quite a few printers from the biggest manufacturers. The other school of thought trundles down the path of ARM, with the most popular boards running the Smoothie firmware. There are advantages to running a printer with an ARM microcontroller, and the SmoothieBoard is fantastic.

Re-ARM for RAMPS — a Kickstarter that went live this week — is the middle ground between these two schools of thought. It’s a motherboard for RAMPS, but brings the power of a 32-bit LPC1768 ARM processor for all that smooth acceleration, fine control, and expansion abilities the SmoothieBoard brings.
