32-bit boards solve these sort of problems twofold: by having more power to do these calculations and having the room to look further ahead with movements to, for the most part, stay ahead of the curve not have those stutters.įor communication, the most common connector for boards USB Type A, but I have seen others that have USB micro or USB mini. When it’s stuck calculating things, the rest of the system doesn’t know what to do until it’s finished computing the next line, creating a stutter at best or a pause at worst in your print. Think about it this way: the board needs to both calculate how to move and dictate to the motors to move in a specific direction and acceleration, which is a lot of information to compute. If you’re at all familiar with computers or video games, then you might be thinking “these can’t mean the same thing.” Yes, a huge number of 3D printers are running on processors that have nearly the same capabilities as the processor in a Nintendo Entertainment System, and in many cases, just at the threshold of having enough processing power to compute the movements necessary for a 3D printer.ĭelta 3D printers need to do a lot of calculations to figure out how to move their three motors at the same time, and that can choke up the processor. Some of them are 8-bit, like the ATmega2560, and others are 32-bit like ARM processors. No matter what controller board you’re looking at, there will be a chip on it that does all the computing.
