Christopher Robertson has created a new 3D printer filament roller and feeder which offers an all-in-one IR sensor and alarm to detect all filament feeding errors automatically to help stop your printer when the need arises.
The 3D printing filament roller supports OctoPrint and Marlin 1.1.x and has this week launched by Kickstarter to raise the $11,250 required to take the hardware into production. Watch the demonstration video below to learn more about the filament roller which is available to back by Kickstarter with pledges starting from $44.
Features of the 3D printer filament roller and feeder include :
• The Filament Roller uses a printed control wheel and infra-red sensors to detect movement from your filament.
• An on-board processor counts direction and speed so it can’t be fooled by retraction. It also doesn’t add any burden to your printer’s processor, no software modification required, and no software bugs!
• An alarm timer is set using a small dial (3 to 48 sec.).
• An LED strobes for each change in position so you can tell if it is working at-a-glance.
• The alarm is triggered when no net movement is detected before the timer expires.
• An error signal output can be connected from the Filament Roller to your printer’s end-stop input (Marlin 1.1.x, RepRap) or OctoPrint (Filament Sensor Plugin, Raspberry Pi) to automatically pause your print!
• A 100 dB buzzer will alert you when your filament has stopped. The buzzer can be enabled or disabled using a switch.
• The Filament Roller can be powered directly from your printer’s 5 volt supply all the way to a 24 volt external power supply. The power switch toggles between the two different power inputs.
