The firmware and opensource about CERAMBOT The system firmware of the CERAMBOT printer is modified based on marlin and mainly utilizes functions such as M163. We want to use CERAMBOT as an open platform to print a variety of viscous fluids in addition to printing clay. More open source materials can also be found here: Https://www.thingiverse.com/groups/cerambot

Among them, if the length of the carbon rod center of your device is 250mm, then you need to modify it as follows:

// Center-to-center distance of the holes in the diagonal push rods.

#define DELTA_DIAGONAL_ROD 250.00 // mm

If the length of the carbon rod center of your device is 270mm, you need to modify it as follows:

// Center-to-center distance of the holes in the diagonal push rods.

#define DELTA_DIAGONAL_ROD 270.00 // mm

Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. First created in 2011 for RepRap and Ultimaker printers, today Marlin drives a majority of the world's most popular 3D printers. Marlin delivers outstanding print quality with unprecedented control over the process.

The 1.1.x branch is home to all tagged releases of Marlin 1.1 (final version 1.1.9 – July 2018).

This branch will receive no further updates. All future development —including all bug fixes— will take place in the bugfix-2.0.x branch, which will also serve as the root for all future Marlin development. Be sure to test bugfix-2.0.x before reporting any bugs you find in 1.1.9.

Marlin 1.1.9 is the final release of the 8-bit flat version of Marlin Firmware. A monumental amount of talent and effort has gone into its production, and thanks are due to many people around the world. Throughout Marlin 1.1 development we worked closely with the community, contributors, vendors, host developers, library developers, etc. to improve the quality, configurability, and compatibility of Marlin Firmware, all while continuing to support a wide variety of Arduino-based boards.

Previous releases of Marlin include 1.0.2-2 (December 2016) and 1.0.1 (December 2014). Any version of Marlin prior to 1.0.1 (when we started tagging versions) can be collectively referred to as Marlin 1.0.0.

Marlin is published under the GPLv3 license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
