If that’s not fast enough, check out this cube at 150 mm/s (wait for the first layer to finish) from : You can see a video, below, of printing at 100 mm/s using Klipper. When properly tuned, pressure advance reduces extruder ooze, possibly allowing faster printing. Klipper implements a “pressure advance” algorithm for extruders. Higher stepper rates enable higher print velocities.Īt high print speeds, oozing can be a problem. An older AVR can apparently achieve rates of over 175,000 steps per second and rates up to 500,000 per second are possible. Klipper is able to achieve precise high stepping rates. The firmware is simple and in C so it can support many microprocessors including common 8-bit and 32-bit CPUs found in 3D printers. Since the microcontroller firmware is very simple, it is easy to reconfigure things in Klipper just by changing a file on the host computer. More precise stepper movement translates to quieter and more stable printer operation. It calculates precise step times based on the physics of acceleration and the physics of the machine kinematics.

The software does not use kinematic estimations (such as the Bresenham algorithm). Klipper touts several “compelling features”:Įach stepper event is scheduled with a precision of 25 microseconds or better. Of course, that assumes your hardware can handle a faster rate. Because it is simple, you could have a small CPU and you could possibly get much faster rates. Most of those are related to something to do at a given time: operating a stepper motor or setting a PWM output. The microcontroller firmware only has a handful of commands. The host can talk to Octoprint and you can run that on the same Raspberry Pi that runs Klipper. There’s a small bit of firmware you program on the microcontroller that speaks a lightweight protocol to the host computer. The BeagleBone will work and - in theory, at least - so will any Linux computer. The host computer doesn’t even have to be a Raspberry Pi.

You can use Klipper with a Cartesian machine, a delta, or a Core XY-style printer. Klipper can control multiple microprocessors with no trouble and keeps them in synchronization, so you could have a processor for your extruder and one for each stepper, for example. The microprocessor then handles the timing and things like motion control for the axes and extruder. It communicates with the onboard microprocessor by providing a schedule of when to do what tasks.

Klipper is mostly written in Python and it does most of the functions of traditional 3D printing firmware. Would it make more sense to do things like parse G-code, map out curves, and set accelerations in the relatively powerful Raspberry Pi and relegate the 8-bit AVR to just commanding motors and heaters? thinks so, and he wrote Klipper to prove it. It isn’t uncommon to see a Raspberry Pi connected to a printer, too, but - again, in general - it is a network interface that handles sending G-code to the 8-bit controller that runs the stepper motors. There are a few 32-bit boards, but if you grab a random 3D printer, its brain is going to be an 8-bit AVR running something like Marlin or Repetier. There are some exceptions, but most 3D printers run on either an 8-bit Arduino or some Arduino variant with a lot of I/O. Although we tend to think of 3D printers as high-tech toys, most of them are not especially powerful in the brain department.
