We recently released RepRapFirmware 3.4.0 with many new features, including these:
- Input shaping, which reduces the resonances that cause ghosting on prints, allowing better print quality at high print speeds
- Heater feedforward based on extrusion rate, which helps maintain extruder temperature when using high flow rate extruders
- The file listing in the web interface and in the file information page of PanelDue now display thumbnail images of the print (requires compatible slicer)
There are many other feature improvements, including improvements to conditional GCode expressions, the ability to use multiple outputs to control a single logical heater, and support for the EXP1HCL closed loop stepper board.
