Welcome fellow prototypers! This communities' purpose is to help others and share functional 3D Printing related information. While other 3D Printing Communities are a good resource, sometimes too many help posts get buried under memes and fluff. This will remain technically focused and keep the fluff removed. Please help your fellow 3D Printer hobbyists as much as you can with their issues! and showcase your functional prints and how you use or created them.

Remaining Filament Tracking (self.functionalprint)

Is there a way I can track how much filament is left on a roll?
Either an add-on sensor I can build or software that will track how much is used vs how much is supposed to be on the roll?

Have a Prusa Mk4 and it's working ok so far but been having trouble with very long prints so trying to figure out if my rolls have enough left

Here's what you can do.

Look up instructions for your slicer on how to get the weight (in grams) of an object before it prints.

Take your spool, and weigh it -- ideally with a kitchen scale, in grams.

Go to this website and find your empty spool weight.

Subtract the spool weight from the kitchen scale weight. This is how much filament you have left.

Compare the number from your slicer to the filament you have left.

If you'd like, you can also look into getting a filament runout sensor so you don't have to hover over your printer to catch when exactly it runs out of filament. It'll automatically stop the print so you can replace to spool.
