SD CARDS - NAVIGATION
From Repetier Server console, with special "DOS-LIKE" commands.
EASIER and FASTER than using gcodes with no signification...
Those commands are intercepted before going to the Gcode PARSER
and are only available when the printer is not busy printing.
S: Select external SD CARD and list the ROOT dir
M: Select internal MicroSD and list the ROOT dir
CD.. Go up one level towards ROOT
DIR List all files in current directory, not only Gcode.
( YYYY-MM-DD HH:MM AM <DIR> or FILESIZE LONGFILENAME )
DIR ext List only the files matching the ext provided extension. Ex. gcode , gco "Dir gco"
CD dir Enter Directory
MKDIR dir Create a new folder in current directory (NO PATH ALLOWED)
DEL filename Delete the FILENAME in current directory (NO PATH ALLOWED)
RMDIR dir Remove a directory in current directory (NO PATH ALLOWED)
COPY source destination S:/path/path/filename M:/path/path/ ex: S:/SYS/ddd/this.gcode M:/old_files/
RENAME oldname newname RENAME A FILE OR A DIRECTORY in the current directory (NO PATH ALLOWED)
INFO filename.gco Display informatons about any gcode files.
( layer height / layer count / filament needed / Est. print time )
VIEW filename.gco Display the first 250 lines as ascii text (.gco .txt ETC)
VIEW filename.xyz Display the first 250 lines as 16 Hex bytes per line. (.bin .bkp .bmp .png .dat ETC)
PRINT filename.gco Start to print the selected gcode file.
Note 1.
Because of the small size for parameter storage (512 bytes), a 128K flash memory sector is used as permanent storage.
The sector can be partially written 256 times (512 bytes per backup) before requiring a complete sector wipe,
to restart the same process again. (That was 1 write cycle). The flash memory minimum write cycles guaranteed for the
STM32F407 MCU by ST Microelectronics are 10000, yielding a total of 2.56 million times, parameters can be saved.
With Druid Firmware, you no longer have to worry about saving your newly modified settings. Druid firmware save them in a temporary file as you make them. At every Boot, it loads the settings from the FLASH memory block, and also read the temp file and apply the previously modified settings to the RAM, seamlessly. When the size of the temporary file is above the limit set by the users, or when using M500, Druid Firmware merge theses changes and write all settings to the next 512 byte block in the flash, and delete the temporary file.
Druid Firmware also innovate with a QUADRIPLE firmware boot selection!!! The user can choose in the GUI, what firmware to use at next boot, up to 4 different can be placed in the folder "FIRMWARE" on the external SD CARD. Ex. Dremel original / Druid 1.0 / Druid 1.2 / Marlin 2.01 ... it keeps track of their settings and restore them when needed.
Druid Firmware is now fully compatible with Repetier Server, and has been added in their setting menu. All the parameters will be automatically detected... We have worked with Repetier Lead programmer to made all the needed changes in both applications (Druid firmware and Repetier Server) and we will continue to improve the possibilities...
