Monitor how a lot 3D printing filament you’ve got

3D printing fans keen on having the ability to monitor how 3D printing filament they left on their reels. You is likely to be keen on a brand new Arduino challenge that lets you simply see the precise quantity of filament remaining with out the necessity for any further software program or app. The helpful display screen will be hooked up to your 3D printer and supplies a show and makes use of a scale to offer an correct calculation of the precise quantity of filament left in your spool. The challenge was created by Instructables member InterlinkKnight and kindly posted so that you can do it your self.

3D printing filament monitor

“That is my DIY filament holder with built-in scale for my 3D printer, utilizing arduino, a load cell and an OLED show. The primary distinction between this and a typical scale is that this machine has the flexibility so as to add a number of profiles to retailer completely different tare values ​​in order that we will solely measure the burden of the remaining filament excluding the burden of the empty spool, as every model of filaments has a special weight and materials for the spool itself.

Options:

– It may possibly measure weights from 10g to 9999g.
– There are 3 buttons (LEFT, ENTER, RIGHT) which can be utilized to scroll via the completely different profiles and navigate the menu system.
– You may add, edit and delete profiles utilizing the menu system. It may possibly retailer as much as 20 profiles, with their very own identify and tare worth. Most 21 characters for the identify of every profile.
– You may carry out a full load cell calibration utilizing the menu system, so there is no such thing as a want to switch the sketch in any manner.
– Configurable lifeless zone with real-time studying on the display screen. The lifeless zone helps ignore fluctuations within the fixed pull/thrust of the filament within the 3D printer, so we present essentially the most reasonable estimate of the particular weight remaining within the spool.
– All settings are saved in EEPROM in order that it remembers all settings after turning off the machine.
– There’s an choice within the menu for FACTORY RESET arduino to erase the EEPROM (consumer information).
– Routinely heart title textual content in major/regular display screen ignoring trailing areas.
– When including a brand new profile, it’ll save the brand new profile after the present profile in order that the order will be organized in a predictable manner. It took lots of effort to make this work, so when you might take it with no consideration, it is not a trivial characteristic.
– When powering on, altering profiles or coming back from the menu, it shows the burden ranging from the decrease fringe of the lifeless zone in order that the machine is able to instantly measure the lower in filament weight.
– No ready time to be on the menu. Sure, that is proper, it is a characteristic. Why? I hate timeouts that may exit the menu if no operation is finished after a number of seconds, however I believe that is poor design that causes stress and frustration since you really feel like it’s a must to rush issues with the specter of having to start out once more from the start. You are not going to search out something like that right here.

The Arduino Weblog writes:

“Each fashionable slicer available on the market will present a reasonably correct estimate of how a lot filament (by mass and size) a job would require. To find out you probably have sufficient filament, all it’s essential know is the size of filament remaining on the spool or its weight. Figuring out size is almost unimaginable except you monitor feed over time, however weighing filament is straightforward. So long as you possibly can subtract the burden of the spool (set tare), you You may decide you probably have sufficient filament.This machine each weighs the present spool and subtracts the tare.”
