Showing ETA/ETL progress on LCD Screen

[bratan]

Is there any way to send remaining print time and progress percentage to printer's LCD controller when printing over USB? I know I can see it via Machine Control Panel, but frequently my PC has monitor off and I'd like to see it on the printer's screen (for example CR-10)...

yes it is possible, not with s3d but yes, possible, if you edit your g-code to add M117 with message you want shown on your LCD.

i do not own cr10 so can't say if it supports M117but most printers nowdays do

this is actually a good idea, I might add this option to my gcodestat so that it adds these M117 into code with real timing info

I modified gcodestat to add M117 codes into the g-code. The frequency of the M117 commands is controlled by -s or --percent_step value so -s 10 will give you 100%, 90%, 80% ... codes, if you go with -s 1 you will get 100%, 99%, 98%... (default is 10)

-o parameter selects where you want to save the new, modified file (if -o or --output are omitted the M117 will not be added and no new file will be generated, only the time will be calculated and displayed)

-q will prevent anytyhing being displayed on the screen (except for errors, those will be sent to stderr)

use -? to get all parameters

Oh wow, that's very clever! Thanks!

I might have some free time now during holidays so it's possible I add few more functions if I get some ideas so ideas welcome .. also I'll probbly add full marlin support too (right now if you leave junction deviation as default and just use acceleration it is very close to marlin speeds but I want to add 100% accuracy if I can spare some time)
