"Marginal Gains" Release - 119r14

Quick Start   Wiki Pages  

Work on improving the machine's auto-calibration has stalled -- this release contains the "prep work" to perhaps overhaul Marlin's auto-calibration process, along with a few other small changes some might find useful. I thought I'd push these small changes out since the current main objective (improved auto-calibration) has been elusive.

Please note: when installing or upgrading, the firmware may not properly detect and correct errors in the flash memory used to store its settings. Bizarre or erratic motion is a strong indication that there is a problem with the settings. The M502 (load factory settings) command followed by the M500 (save settings) command should get the firmware operating from a known "ground" state.

Notable changes

  • SD card contents: include SHA1 hashes for the firmware files, and place M851 setup commands in their own folder (thanks to @mulcmu for these suggestions);

  • change the bed probe tapping for the G29, G30, and G33 codes from three (3) averaged taps to two (2) fast/slow taps and adjust the tap speeds;

  • bump the "maximum extrude length" limit from 500mm to 600mm; and

  • tweak the bed probe compensation parameters (more of an experiment than an improvement).
