Intelligent Clever Filament Runout/Jam Detector
Description
Clever Filament Runout/Jam Detector NB: on some long 3D Prints this still returns FALSE POSITIVES, filament runout even when the filament has NOT run out. I think this may be because as the filament goes between the dual cogs they get pushed apart and the teeth hardly mesh. This may cause the cogs to stick and the encoder wheel to stop turning, triggering the filament out signal. Clever Filament Runout Jam Detector does NOT return False Positives. YES it does return False Positives on very long 3D prints Use an 3D Printed encoder wheel to trigger an Optical Endstop Clever Filament Runout Jam Detector Part 1 (some No false positives fixed below, easy) https://youtu.be/PSetR9-BrtM Clever Filament Runout Fix for BTT Smart Runout Detector Part 2 No false positives https://youtu.be/IKHTXYuorLQ Filament actually moving may be vied by the encoder wheel turning or the Optical endstop- LED flashing Dual Gear. I cannibalised a Metal Extruder Remote Dual Drive Gear Creality 3D Printer Ender Accessories S3. .. NOTE::: BOTH the Bigtree Tech Smart Filament Detector and this unit return a signal that the filament is OUT even when the filament is present, false triggering. Because both do the same false triggering. Looking online indicates false triggering is a common issue. * In My case I found that the Top Clamp that grips the Filament was catching on the washers I used. This caused the filament to slip and not always turn the encoder wheel resulting in false triggers; This may not be the only issue. Testing removing the washers soon.
