Show information about the print progress on LCD

M531 filename - Set the filename being printed. M532 X L<curLayer> - Update current print state progress (X=0..100) and layer L.

This allows a host to enable a special information mode on LCD display, so users see progress in percent, model being printed, layer being printed, and total layer count. (Hosts can also use M117 )

@probonopd this should be addressed by version 2.0. Only thing missing is L. Cura gives info in gcode but I don't know if all slicers does this and if they does, if they uses same format

We are already calculating the percentage for /api/job (completion), now we "just" need to find a way to send it to the LCD from time to time. I'd be fine with a "normal" M117 if we don't have L for now.

M73 is still supported if printer report capability to handle it

Only the last one works on the Prusa:

>M115
<FIRMWARE_NAME:Marlin V1.0.2; Sprinter/grbl mashup for gen6 FIRMWARE_URL:https://github.com/prusa3d/Prusa-i3-Plus/ PROTOCOL_VERSION:1.0 MACHINE_TYPE:Prusa i3 MK2 EXTRUDER_COUNT:1 UUID:00000000-0000-0000-0000-000000000000#wait more#

<ok#ok#

>M73 P75
<Invalid M code.#wait more#
<ok#ok#

>M117 Printing... 75%
<ok#ok#
>M105

That's at least better than just showing "Printing...".

Second printer, Renkforce RF100 with OEM firmware:

>M115
<FIRMWARE_NAME:Marlin V1; Sprinter/grbl mashup for gen6 FIRMWARE_URL:https://github.com/MarlinFirmware/Marlin PROTOCOL_VERSION:1.0 MACHINE_TYPE:3D Printer EXTRUDER_COUNT:1 UUID:00000000-0000-0000-0000-000000000000#wait more#
<ok#ok#

>M531 filename
<ok#ok#

>M532 75 20
<ok#ok#

>M532 P75 20
<ok#ok#

>M73 75
<ok#ok#

>M117 Printing... 75%
<ok#ok#

We get "OK" here but no change on the LCD; only the last command does something visible.

all of that depends on firmware...if firwmware supports them then it is supposed it will do something on LCD

GMagician avatar Mar 03 '19 14:03 GMagician

Yes, so let's use what works on all (most) printers. Then we can improve later from there.
