  • This is a custom version of the Marlin Firmware specifically modified for 3Drag 3D printer used in LDM mode. LDM (liquid Deposition Modeling) is a particular 3D printer process in which viscous fluids are extruded from a reservoir and deposited on the build plate. This process is more generally called Direct Ink Writing (DIW). Firmware Major mods - E0 and E1 thermistors have been set to dummy (no heating required to extrude viscous fluids) - The micro-steps were set to 16 for the X, Y, and Z axis and 8 for E0 axis. - _DEFAULT_AXIS_STEPS_PER_UNIT_ for E0 motor has been modified to 400 if using the 2:1 reduction gearbox or 800 if using 4:1 reduction gearbox. More information available here. - Check if the defined motherboard matches the one you are using. It was set as _BOARD_MEGATRONICS_3_ since Megatronics 3.0 mainboard was used. - Version 2 of the firmware can be used to control the UV curing addon as a second extruder. Moreover, it was developed from Marlin 2.07.2 which added many features for 3D printers enabling a more advanced configuration of custom 3D printers. About Marlin Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Updated Marlin firmware are available at the Marlin Releases page. Additional documentation can be found at the Marlin Home Page. Disclaimer Flashing a custom firmware happens at your own risk.
