Marlin firmware builds

Touch Mi - Marlin-bugfix-1.1.x

I use this one on my Ender 3 with a Touch Mi

Configuration.h and Configuration_adv.h are based on Hotends.fr docs with some more modifications. I used Marlin-bugfix-1.1.x and not the sources provided by hotends.fr, so i don't have the Touch Mi custom menus.

• S_CURVE_ACCELERATION is enabled (see https://github.com/synthetos/TinyG/wiki/Jerk-Controlled-Motion-Explained)
• PIDTEMPBED is enabled
• RESTORE_LEVELING_AFTER_G28 is enabled (see G29 ABL for details)
• ENABLE_LEVELING_FADE_HEIGHT is enabled (see Marlin issue #7562 for details)
• I need moar PROGMEM and use OctoPrint, SDSUPPORT is disabled , so i can keep DISABLE_M503 commented
• Step/mm, PIDs are feeded from my own values.
• GRID_MAX_POINTS_X & GRID_MAX_POINTS_Y are set to 5
• *_PROBE_BED_POSITION defines are updated (see Below)

I've modified the *_PROBE_BED_POSITION defines to use probe offsets

// Set the boundaries for probing (where the probe can reach).
#define LEFT_PROBE_BED_POSITION MIN_PROBE_EDGE
#define RIGHT_PROBE_BED_POSITION (X_BED_SIZE + X_PROBE_OFFSET_FROM_EXTRUDER - MIN_PROBE_EDGE)
#define FRONT_PROBE_BED_POSITION MIN_PROBE_EDGE
#define BACK_PROBE_BED_POSITION (Y_BED_SIZE + Y_PROBE_OFFSET_FROM_EXTRUDER - MIN_PROBE_EDGE)

NOTES : PID values are for my 0.4mm steel nozzle and borosillicate bed. Ender 3 is mainly stock, the only hardware updates atm are dampers on all stepper and TLSmoothers on X,Y & Z.

Some explainations about how it used id in the Wiki

TODO : increase BLOCK_BUFFER_SIZE, MAX_CMD_SIZE, and BUFSIZE

Touch Mi - Marlin-1.1.9-Ender3.fr

This one is based on the Marlin mods made by [ender3.fr]() and [hotends.fr]().

I've done some update in their configuration :

• LIN_ADVANCE is disabled. I don't need it atm, and too complex to maintain for bowden
• S_CURVE_ACCELERATION is enabled (see https://github.com/synthetos/TinyG/wiki/Jerk-Controlled-Motion-Explained)
• PIDTEMPBED is enabled
• RESTORE_LEVELING_AFTER_G28 is enabled (see G29 ABL for details)
• ENABLE_LEVELING_FADE_HEIGHT is enabled (see Marlin issue #7562 for details)
• I need moar PROGMEM and use OctoPrint, SDSUPPORT is disabled , so i can comment back DISABLE_M503
• Step/mm, PIDs are feeded from my own values.
• GRID_MAX_POINTS_X & GRID_MAX_POINTS_Y are set to 5
• enabled G26_MESH_VALIDATION for test purposes
