Hi
Im sitting on a Wanhao Duplicator I3.
And i wonder if anyone know if there is possible to send a signal ti the card to pause.
I like to take a sensor that feels when the filament is out and set the printer in pause until i get home.
or maybe it already exist.
was thinking on building something with aruduino and something that move the control button.
is the heated bed warming your bum? =P
Haven’t heard of anything but that doesn’t mean it’s not possible. Since the Duplicator i3 isn’t huge I ca t imagine printing something that would require more than a full spool of filament. I just look at how much is needed on Simplify 3D and make sure I have enough
I think I know what you mean, your English is not good but as I am an houfener, I have the same problem, I would think the way to go is by using a Bowden filament feed and a USB link. the slicer prog already provides the capability to track the amount of filament run, this can guestimate the amount left on a roll, then when this figure reached, send pause instruction to controller via USB. Simples, no hardware nessasary.
Yeah. Was hopping that I could set up a reading fork and that send a signal when nothing is between.
But that maybe a conputet is needed to send commands over the USB.
Maybe a usb from the ardoino to the printer usb. But then a serial conunication handle is needed.
Want to run rolls with a little filament left and it pause automatically to I just put on the next roll.
what slicer prog you running. I always run through my PC, miles easyier to control. Rather than the senders hardware, ( just something else to break) use the prog that’s already written for you. introduce a running total of feed in G code, store when run. when filament gustimate runs out. insert g code for pause. Yes your pc will be on when you not their but if you use cameras, other heatsensors, etc to run “lights out” then its no hardship.
sorry, you have got a computer as well as the printer , haven’t you?
Run the slicer on the computer and put the g code on the micro sd and put it in The printer.
But maybe it’s a good idea to try to connect a computer and see how well that works.
Mount a new limit switch?
Hi @Lenny_Boris_Fre does this happen to you often? Personally (and please don’t take this as a criticism), I don’t start prints that don’t have enough filament to finish. I’m just wondering if you could go through a lot of work and effort to detect something that really doesn’t happen that often, and if it does to you, could be solved by changing the way you manage filament stocks…
You could look at Octoprint, which runs on a Raspberry Pi. This has the capability to stream a camera to a web page which, with some network magic, could potentially be accessed remotely. The web interface also allows you to control the printer, including pausing I believe.
This is a filament monitor.
It connects to your motherboard.
It is arduino based.
