feature request: filament length left to use

Thu Feb 22, 2018 6:16 am

s3d calculates how much filament is needed for a print, why not expand that to show in the machine control how much is used of that/ what is left?

example: at the end my roll i can see aproximately how much is left, if i could see when printing how much the print has used so far and what is left to use?

I second this! it would be great to be able to enter the size of the roll and have the software keep track. i'm guessing that you would have to have a table to store a user defined roll Id to allow us to select which roll we are using. Roll selection could be phase 2. First release could just assume the same roll until user enters new roll weight.

A nice idea........but one wonders how S3D will actually know how much filament is on the spool of filament loaded in the machine.

Full reels of filament are filled and sold by weight....not but the actual length could vary by say 1 to 2%. That's something in the order of 3 to 6 m of filament for a 1Kg spool.

This is not a new problem. Ask anyone involved in the manufacture of electrical cables. To create a 500m length of multicore cable, they have to start with creating the individual cores in lengths of say 520m to ensure the made-up cable can be cut down to the desired length without losing any of the cores!

Apart from that, its like the "thrill of the race" estimating how much filament you have left and having to decide if there's enough to print the next piece. Lets face can get too boring if you hand over too much to machines!! ;) ;) ;) ;)
