"Extras" Release - 119r09

Quick Start

With this firmware release, we've fixed a few bugs, updated some documentation, and added a few extras to the contents of the micro SD card image. The big news is that finally, we've an Octoprint plugin and Pronterface script that exploits the firmware's M990 command to quickly upload a G-code file to the printer's micro SD card. These are early versions, but they do seem to work.

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

  • The wiki is updated with some tips on using the firmware with 1/8 microstepping versions of the MP Mini Delta printer. We also include a new command in the /setup_gcode folder on the micro SD card to provide correct default values for these printers:

    M92_XYZ57_E48.gcode  - set alternate defaults for 1/8 microstepping printers

  • The firmware now displays a message when the manual "jogging" of the E axis is prevented by Marlin's safety checks. Marlin normally does not allow "cold" extrusion by disabling the E axis stepper while the nozzle temperature is below 170°C. We also include a new command in the /setup_gcode folder on the micro SD card to (temporarily) override this safety feature:

    M302_P1_COLD_E.gcode - allow E-axis stepping regardless of nozzle temperature

  • The contents of the micro SD card image now contains an Octoprint plugin to provide faster uploads of G-code files from the Octoprint host to the micro SD card in the MP Mini Delta printer. (see Octoprint-plugin)

  • The contents of the micro SD card image now contains a Pronterface script and command to provide faster uploads of G-code files from the Pronterface host to the micro SD card in the MP Mini Delta printer. (see Pronterface tips)

  • We worked around a Marlin issue that causes problems with motion during the G29 (auto bed leveling) command. Specifically, motion commands queued during the G29 command did not execute reliably.
