A OctoPrint-Plugin that sends the current progress of a print via M117 command to the printer-display and also to the top navigation bar.

A new feature is the "Desktop Printer-Display", which shows all M117 messages in a Desktop PopUp.

It shows the percentage, the current layer, total layer count, current height, total height, feedrate and fanspeed:

• Printer Display: 50% L=60/120 H=23mm/47mm
• NavBar: Layer: 60 / 120 Height: 23mm of 47mm

Output pattern is adjustable!

ATTENTION:

• The layer information works only when the slicer adds "layer-indicator" to the g-code (CURA-Example as comments like ;LAYER:10). Then these indicators are parsed via a regular-expression.
• Currently supported slicers: CURA, Simplify3D, KISSlicer. You can add your own layer-expressions in Plugin-Settings. If you want to use "slic3r", see Enhancement #8
• Sometimes there is a "Post Processing script" that deletes all comments (e.g. see Issue #33)
• You need to upload your G-Code after installation of the plugin again (if you want to reuse already stored models in OctoPrint), because while uploading the G-Code is modfied
• The total height "calculation" can be done in two ways: 1)the max Z-Value in the G-Code, 2) max Z-Value with extrusion in this height
• The height/layer information is sometimes not matching with G-Code Viewer, because the viewer did a lot of "magic" (e.g. add extrusion diameter to height)

Comment Format Examples:

CURA: ;LAYER:10

Simplify3D: ; layer 10, Z = 1.640

The implementation is based on four steps:

1. PreProcessing the uploaded G-Code (replace layer-comment with M117)
2. Read total layer count from G-Code before start (used last layer-comment)
3. G-Code-Hook to collect the current layer information (M117-command from step 1)
4. Progress-Hook to write all information to the printer/navbar
