All,
I’m i new user of the Vertex 3D.
I was wondering if someone uses an Android app to control the printer and/or an app to slice on Android device.?
Even when you’ve got an other solution to use the Vertex in combination with Android devices, please share this “killer” app.
Thanks.
For something to do with android, that’s 299 USD more than I’d like to spend 
I don’t need extra hardware. My vertex is constantly connected to a internet connected outer… Anyone have any ideas to solve this software-wise?
Why not use OctoPi to control the printer? I control it using the web interface on my android phone all the time.
Alright, could you tell more about that? Been googling a bit, but find it unclear. Octopi is some sort of raspberry pi thingy? And what kind of alterations do I need to do? Maybe it shows but i’m in the dark here lol
Hi there
sorry for the late reply. Yes, there’s a bit to it. But it’s not that difficult. Basically you need a Raspberry Pi and a Pi Cam, plus the OctoPi image to put on the Pi, plus (preferably) an ethernet cable to connect it to the internet. It works with wifi but the signal needs to be very strong if you’re using a wifi dongle - essentially the camera doesn’t do sufficient frame updates to give you a smooth picture, you get a lot of lag, etc.
The other thing you need is a voltage reducer. You basically wire up the Pi via the voltage reducer to your power supply on the printer. Mount the Pi Cam (extra long cable is handy here) somewhere it can see the print. Then when you switch on your Vertex, the RPi switches on and fires up OctoPi.
There are various ways to print - my preferred way is to slice the model via Repetier Host on a PC (remember to allocate the correct nozzle!) and then save it to SD card. Then insert the SD card into the LCD unit on the printer which the Pi can read. You then fire up your web browser to use the OctoPi interface to control your printer. Any web browser, any device.
If you want to view it from outside your local network, you’ll need to set a static IP address and port forwarding for the Pi via your firewall software. Then find out what your dynamic IP address is before leaving the house. When you try and connect to that address from outside, the port forwarding rules should take you straight to the OctoPi’s web server interface and you can control your printer as if you were sitting next to it.
It’s a nice system, it means you can walk away from the printer and leave it printing on those 15 hour prints. If the camera shows something has happened, you can stop the print, lower the bed and shut it all down remotely. 
Thanks for sharing your input Biscuitlad.
Seems a nice solution with the Pi Cam.
Maybe its solves a few of my “problems” while i’m not at the site of the printer.
I’ll will investigate your tips futher.
Hy,
i buy this today and i made first tests… it works fine…
