Laser filament monitor
-
Development of the laser filament monitor has stalled because we are too busy with other things at present. We might be willing to supply one of our prototypes to a user who meets the following conditions, to try to speed up finishing it:
- Must have a functioning 3D printer and a supply of black PLA to print small parts with;
- Must have enough experience of OpenSCAD to modify an existing design and preferably do new designs;
- Preferably either be located in the UK or have experience of programming an attiny microcontroller e.g. with an AVRISP Mk2 or an Arduino running ArduinoISP + 6-pin programing connector.
Having lost yet another piece, this one a 19h print because of a "knot" on the filament roll, I'm highly motivated to get a laser filament monitor.
Is this opportunity still on the table?
Have almost 2 printers (finishing up a HEVO), Duet Wifis and just got an IR probe.
Not an OpenSCAD expert but hey if it's programmable…
Lots of Arduinos and other microcontrollers and programmers.
Portugal based but willing to pay for all expenses. -
Are these still available? to US?
-
We are making a batch of prototype laser filament monitors later this month.
-
I'm interested to test one of these, with a few folks of our hackerspace, in France (https://www.logre.eu/wiki)... we have all asked skills.

@dc42
I would be very interested in working on this, I PM'ed you a couple of weeks ago regarding assisting with the laser filament monitor. I am located in the USA with the needed tools to program the attiny. I can even do smd board assembly if needed. -
I am compiling a list big people who have volunteered, thanks! It will be at least 4 weeks before we get the components and I intend to test a large batch to looks for consistency first. Updates to follow.
-
Please add me to the beta test list also. I am happy to test and report and plan to buy several for my machines on release.
-
@T3P3Tony please count me in if there is still room for more testers
-
@t3p3tony Please add me to the list to purchase beta board. i have been looking forward to testing one out since moving from ramps to DUET.

I think I meet those requirements and would like to test one of these.
-
i would like to purchase 2 when they come available to run on my IDEX machine.

We expect to have plenty of these beta units available for purchase. We know that they can detect reliably when the filament has run out, or when it has become stuck because of a total nozzle blockage - just like the laser filament sensor on the genuine Prusa i3. But we were hoping to do better than that. What we can't guarantee is that these sensors will be able to alert you to a problem that reduces the actual extrusion amount by a substantial proportion, when some extrusion is still occurring.
-
I would also like to buy some sensors for my 3 printers, I have 2 deltas and a core xy with 3 duet wifi and it is a complement that I think is essential for long impressions. Thinking about the quality of their products, this sensor will be wonderful. I hope news.

If there's still room on the list, I meet these criteria (aside from having black PLA, but that's just an Amazon prime order away).
I also have an AVRISP MK2, and an ATMEL-ICE (I'd intended to have a go at developing on the RepRapFirmware, and doing on board debugging, at some point, but have been too busy with work).

Hi can you add me to the list please i believe i have the required skills and i have a large format delta capable of printing small parts and also very large parts some prints running for 3 weeks
-
could you please add myself to the list of people interesed in a beta laser-filament-monitor?
-
Can you add me to the list I have a print farm that i am converting over to duet's and filament monitoring is a must. Happy at the moment if it just detects a jam or filament out.
-
I know it is realy hard to say but will this Sensor cost less than 50$ and will it be avaible at 2018?
-
@as-3d-druck yes and yes
-
Nice thank you.
