OctoPrint-E3v3seprintjobdetails

This Plugin enable the communication with the modified firmware of the Ender 3V3SE and Octoprint to Render in the Printer's LCD the current print JOB. For this was created a custom Command O9000 to send and update the job details.

Setup

Install via the bundled Plugin Manager or manually using this URL:

https://github.com/navaismo/OctoPrint-E3v3seprintjobdetails/archive/main.zip

Dependiencies

To work correctly this plugin depends on the below 3rd party plugins:

• Dashboard.
• GcodeViewer.
• PrintTimeGenius.

To see correctly the layer progress you must wait till GcodeViewer analyse the file, after that you can start the print. PrintTime Genius Provides the Estimated Print Time.

Usualy I load the file and when I see the screen in the LCD I check if gcodeviewer finished and then I press print to start the job.

Selection between O9000 and M117 commands.

Since some users has already plugins that send M117 commands to the printer, I've updated the Octoprint plugin to select which messages to reflect in the LCD and avoid overlapping in the screen. If you want to see the DisplayLayerProgress messages or any other plugin that already sent info to the LCD just keep the seecto disabled. If you want to see the Jobs details in the LCD enable the selector to send only the O9000 commands from Octoprint.

Fine tunning for canceling and pausing/resuming jobs

To have a better controel of messages and printer moves you may want to add this block codes to the GCODE SCRIPTS section of Octoprint settings:

After print Job is Cancelled

; relative moving
G91
; move head 10mm up
G1 Z10 F800
; absolute moving
G90

; move print head out of the way
G1 X0 Y220 F3000

; disable motors
M84

; disable all heaters
{% snippet 'disable_hotends' %}
M104 S0 ; Set Hotend to 0

{% snippet 'disable_bed' %}
M140 S0 ; Set Bed to 0

;disable fan
M106 S0

; send message to printer.
M117 Print is cancelled

After print Job is Paused

{% if pause_position.x is not none %}
; relative XYZE
G91
M83

; retract filament of 0.8 mm up, move Z slightly upwards and 
G1 Z+5 E-0.8 F4500

; absolute XYZE
M82
G90

; move to a safe rest position, adjust as necessary
G1 X0 Y220
{% endif %}

Before print Job is Resumed

{% if pause_position.x is not none %}
; relative extruder
M83

; prime nozzle
G1 E-0.8 F4500
G1 E0.8 F4500
G1 E0.8 F4500

; absolute E
M82

; absolute XYZ
G90

; reset E
G92 E{{ pause_position.e }}

; WARNING!!! - use M83 or M82(extruder absolute mode) according what your slicer generates
M83 ; extruder relative mode

; move back to pause position XYZ
G1 X{{ pause_position.x }} Y{{ pause_position.y }} Z{{ pause_position.z }} F4500

; reset to feed rate before pause if available
{% if pause_position.f is not none %}G1 F{{ pause_position.f }}{% endif %}
{% endif %}
