Oh, one thing I guess I should mention: The sensor has a FAULT output (same as the LED), which is programmed to turn on when it detects errors like the filament being outside of the expected diameter range. So with that output, it can be directly used as a filament runout sensor as well, even without firmware support for the InFiDEL's measuring output!

@@alf3071 Yes, this is a really good application example. You could use very cheap filament with this sensor and the sensor tells the machine when the filament is too thick and stops automatically. Furthermore, this sensor would serve as a filament runout sensor. Thus it would be a multifunction filament monitoring sensor.

@TheBPJo 3 жыл бұрын

This is a great idea and project! Some (hopefully helpful) critisism: If I'm not missing something, your sensor only provides the intended information under the assumption that the filament is perfectly round. It measures the diameter at a specific point, but not if the diameter is consistent. So actually you can not transform this into information about adaptation of the flow factor. You mentioned that better quality filaments are usually not oval - but imo they also should have a consistent diameter. I think this is idea has potentially higher impact for cheaper filament and to be able to compensate tolerances better.

This is a good design and your ideal of using a V-slot bearing is a good idea as well. Just to build on the idea a bit, using the V-Slot bearing on the moving arm of the sensor and then using a wheel with a bit more grip on the other wheel with a slotted disk and a photo interrupter would allow for the speed of movement or distance moved through to be measured. This combined with the filament diameter could then not only detect the diameter of the filament but also filament out (can already do this :-) ) but also if the filament jambs of breaks past the sensor. Just a thought. :-) Keep up the good work Ray

Now think about 1Wire protocol, 1Wire can run on long cables nicely, it is pretty stable and is for e.g. used for hvac, fire and similar sensor installations... I2C is terrible on cables especially around noise generators like the extruder motor... look just how many issues with prusa laser sensor board that's on i2c and how for e.g. same sensor from duet that grabs the i2c from sensor with attiny on board next to sensor and sends data to mb via 1wire type signal works without any issues (ignoring issues that sensor can't work with some filaments)

I'd love to know whether actually tracking the filament width makes any practical difference to print quality? i.e. do you get a perceptibly better print with a filament sensor driving the extrusion multiplier live vs just measuring the filament once? Also, given that you presumably need the sensor to be close to the extruder, does the extra weight of the sensor cause increased lag and cause any decrease in print quality? (I presume that getting this working with Bowden setups would be difficult as you'd be measuring the thickness of the filament that the extruder will see sometime in the future of the print, depending on the Bowden length.)

In order for the extruder to compensate the thickness difference of the filament it must know the distance between the sensor and the extruder or? I assume this feeds live data from the point where the bearings touches the filament, but it will take some time before that point of the filament is consumed.

@light-master 3 жыл бұрын

@@danvalnicek What about a series of quick short retracts that cause the filament to move back and forth along only a short distance. Its not unreasonable that a 5mm span of filament might have variations in diameter that are smaller than the measuring capabilities of this, thus unless you used a large distance or time window for detecting motion, you might get false positives within that same 5mm length of filament during the repeated retractions. If you used larger distance or time windows to account for this, then you'd end up in a situation where a legitimate jam or break would take too long to be detected, making recovering from it difficult, if not impossible. Either a modification to this to specifically detect motion, or a secondary external sensor designed for this sole purpose would be a better option.

SIMAX3d being the best I've gotten on amazon and bought recently for $16 per roll to my door next day.
