Hi guys, my name is Chris and I started printing back in April using a clone i3.

It has a pretty weak extruder and I experienced a lot of filament feeding issues resulting in aborted/lost prints. Does anybody else have this problem or just cheap printers like me?

I built my own Infra-Red sensor for filament speed and direction and I use it to let me know when my print is slowing down or completely stopped. Since I started using it, I have been able to save prints before they are completely messed up.

You can already download the mechanical parts for printing here on Thingiverse: http://www.thingiverse.com/thing:1801190
(It makes a decent roller for spools even if you don't have a control board.)

If you are interested in seeing how this project works, then take a look at my project page: http://www.filamentroller.com/how-it-works/

Anyway, I would like to get your feedback and see if this is something that can also help you. I am happy to answer any questions you have, and I am interested in hearing both your positive and negative feedback. I have a thick skin so don't hold back! :cool:

Thanks for looking.

Dude that's cool! Even though my printer doesn't have that problem I've thought of doing something like that to make me feel more confident that the filament will always make it to the extruder.

Hi, thanks for the compliment. =)

I have fixed my extrusion issues but I still use it for every print. It's just too easy not to do it.

If you're interested in getting one, I am starting a Kickstarter campaign this month. See the next post for details.

Since I made my first post, I have made some more progress in making this a better product:
1) You can use this board to automatically pause your print and change filament (M600 gcode). Just plug it into your Marlin/RepRap board's extra end-stop to automatically pause your print.

2) You can use this board to automatically pause your print (just pause) using OctoPrint/RPi. Just download OctoPrint or OctoPi, install the filament sensor plugin, and connect it to this board.

I also will revise the next PCB revision so this board will have some more I/O, and a switch to enable/disable the buzzer. As before, you don't need to develop any software, recompile, or do anything complicated to get this working.

I am almost done, ready to begin a Kickstarter campaign (within 2 weeks?). I should be able to sell a printed & painted wheel, board, bearings, and hardware for $44-50.

By the way, I have a new kickstarter campaign (https://www.kickstarter.com/projects/522476987/filament-roller) up and running.

This product will work with Marlin 1.1.x as an endstop filament runout switch, OctoPrint, or Repetier.

If you have a design request or questions, just post and I'll answer~

I now have a Kickstarter campaign. (https://www.kickstarter.com/projects/522476987/filament-roller)

Check it out!

It works with Marlin 1.1.x, OctoPrint, or Repetier!

If you have questions, then ask at will!
