3DHex is a new experimental host controller firmware that i have just released on
github
I started this project ofline back in 2015 and after a lot of work i managed to get my first prints with pretty sucess. My target was to create an easy to install, easy to configure and use firmware for 3d printers on already existing hardware. I have only made prints with my RAMPS 1.6 + LCD 16x2 with the Host running on windows. Feel free to download my work make tests with others boards modify the source if needed and make pull requests on github.
3DHex is an open source 3D printer firmware. The Host uses the CPU power of any typical desktop computer and generates a binary file. This file then is transfered either via USB or SD Card to the MCU. The MCU sets its outputs according to the raw 0s and 1s that binary file contains.
Features of version 1.0.0
-User friendly configuration ( GUI )
-Jerk free S-Curve velocity profile ( Analytic mathematical equations )
-Either S-Curve or Trapezoid profiles ( Just set Jerk = 0 to switch back to the old classic Trapezoid profile )
-Real arc G02/G03 motion ( Motion accuracy down to microstepping, not line segments used. Also full arc accel/decel either S-curve or Trapezoid profile )
-Jump velocity ( No accelerated velocity to avoid blobing at the corners )
-Basic thermal protection ( Over temperature read, broken or unconnected thermistor detection )
-Tested with RAMPS 1.6 board
-USB printing ( Real time streaming from USB - 15KHz step rate )
-SD Card printing ( Standalone printing, more reliable than USB - 25KHz step rate )
-LCD 16x2 support
-Only for Cartesian 3D printers
