As a few folks have said below, for Creality printers that have backpower issues, cover the fourth pin (5V) on the USB-A connector (host side plug, one that will go into the hub or adapter) with a small bit of electrical tape as well to take some of the strain off these older batteries. Have it working now, and I thank you and the Dev behind this app, for putting in great work!

@RitoriqPrinciples Месяц назад

Even two years later this makes more sense over a Raspberry Pi. With a phone you get all you need, the processing platform, a camera, power source, power backup (at least for the OctoPrint instance) and internet backup (WiFi and 4G or 5G). Additionally, in some setups you need an additional display since some displays can't be connected reliably to a Raspberry Pi.

UI Customizer plugin also gives a better responsive mobile experience for loading the interface on the phone directly and is still actively developed where TouchUI has several plugin conflicts and doesn't seem to be maintained anymore.

@tamasau8725 2 года назад

For you and for everyone: I waited a few weeks to write my opinion. After then I can confirm Octo4a works very well for me. I tested it on more smartphones. It worked also on a quite old Huawei P8 Lite. It runs now on a Huawei P20 Lite without any performace problem. I was able to set the energy management easyly. I made an "Y" cable, but it didn't work for either. It is currently running only on battery power. It lasts even up to a 24 hour of printing, or more. With a very used battery!! Especially when I turn off the camera server. I ordered a USB multiport hub. It's on the way. I hope it will work. I don't want to modify the phone with an additional battery charging module. The only one issue to me is about the camera focus. When I turn off autofocus, everything will be awful blurry. With autofocus too, but not as much as when it's turned off. I saw on github this is a current issue. So I'm waiting it will be fixed sometime. Overall I'm happy. I installed a BLtouch sensor. I was really scared to modify my printer. I scared about changing the firmware and losing the SD support too. But everything works fine. By the way my printer is Anet A8 Plus.

Everything worked fine, even a webcam, but it was incredibly slow. Inspired by your video I converted my old Xiaomi Mi A1 (Android 9, LineageOS) to an octoprint server and everything works flawlessly and the UI is really snappy. Filip did an amazing job on the Android port, thank you very much for bringing it to my attention.

@adamhun994 2 года назад

Thanks Thomas for the info! Yesterday I was finally able to convert my old android phone without a battery to a printer support! I've removed the battery, soldered wires to the test pads (fortunately there were 3 of them for each traces!), added a LM2596s module and a 10k resistor as a thermistor. Without a resistor the phone won't turn on. Previously I've tried several Y microusb OTG cables but the phone stopped charging after a few seconds. This way I can use it until the charger is plugged in.

@adamhun994 2 года назад

Okay, tried printing a few models now and have some trouble maintaining stable connection. I'm getting timeouts randomly and that causes the printer to pause for a few seconds. Sometimes the motherboard disconnects completely and the printer fully stops. I'm not sure if it's some kind of noise, but I'll check with a raspberry pie soon.

Beware of Y-Cables or -Adapters with USB-C, they can be dangerous to the attached printer. If it’s just a dumb Y-Cable and the phone negotiates a higher charging voltage using USB Power Delivery, Quickcharge or similar, the higher voltage might end on the VCC pins of the attached devices, which can lead to the magic smoke beeing emitted from the connected USB devices, including a connected printer mainboard, especially if it has a USB backpowering problem (looking at you, Creality *sigh*). USB-C-Dongles with a dedicated USB-PD-Charging-Port are probably safer.

@vincent.schmandt 2 года назад

@@nobodyontheinternet784 You can also hack the original battery by just taking the small board at the top of the battery, cutting of the battery terminals and replacing those with a usb power supply. It works like a charm, done it with 3 of my old phones.

That's my main concern. We all know it'll run hot while doing a constant process and charging at the same time. I wouldn't leave my house with a lithium bomb in my basement.

Not the case on most phones, not modern ones anyway. Most phones will shut down hard extremely fast if they go more than a couple of seconds without within-spec telemetry readings off the battery. It's not just "black and red wire go brr". There's a reason why most modern smartphone batteries have 4,5,6 pin connectors or more, even from just a single-cell "battery". Most of the little boards generating this telemetry also have e-fuses now (regulation thing I believe, lots of new stuff came in after the Note 7 sagas), so they permabrick if they experience severe undervoltage or full loss of power. Meaning quite often you can't just snip that board off an old battery and hook up a 3.9-4vdc supply to the battery cell tabs and use it like an infinite capscity battery that way. You could _try_ it, just be VERY! careful cutting the tabs, and with the old cell afterwards, as it has no protection at all anymore. Keep that in mind when disposing of it too, tape up and protect those tabs really well. If you wanna try to run it like you suggest, look into higher end model-specific bench PSU power cables for microsoldering repair work. Some of these have built-in electronics to simulate the battery telemetry the phone is requiring, and they have wire gauge morr suitable for sustained load. The low end cables do not have these telemetry emulation circuits, and most androids samsung S3 and newer ish, won't even fully boot up before cutting off without it.

everything has worked out great so far, only thing is, I cant connect my prusa since it is not able to find a fitting baudrate. That was a couple of seconds ago, found the cause: disable the rpi setting within your prusa printer settings.

I run octoprint on a 20 year old laptop, running linux. Works great, it's nice to have a big screen for control and monitoring, but mainly it's just what I used prior to octoprint. A linux install of octoprint is a bit more involved than just running the octopi image, but I had no prior Linux experience when I started and there are guides. You can also run octoprint on windows, but it's not quite ideal compared to Linux apparently.

@DasJev 2 года назад

By flashing your phone the requirement for a battery is dropped on most roms - means your phone can run without a battery, purely on usb power without any hardware modifications.

@zacharyyoung8807 2 года назад

I've tried this in the earlier stages about 6 months ago, but not much since then. much has probably changed since I used this. It's a great piece of software if you're in a pinch and want to try it out, but don't forget an old PC with an installation of linux can run octoprint just the same (plus there's a longer development trail, so it would be generally more reliable.). Great option though for quick setup (except for maybe designing the phone holder). Great Concept though and I bet it will only get better!

I have a pixel 4, which has a front facing IR camera accessible through some forks of open-source android camera apps (specifically, HedgeCam 2 for example) I very excitedly opened the octo4a settings and saw that it listed two front facing cameras... But sadly, the IR one is inaccessible. Oddly enough, there's two rear facing cameras (a normal one and a tele/zoom one) but it only sees one rear facing camera in settings :) At least it seems to be working in "normal" sense, even though I can't take advantage of that specific unique feature :p I quite enjoy using the IR camera as a short range security webcam or as a way to see through IR-transparent plastics but figured it might be useful on a 3D printer webcam setup, as I could run the printer at night but still have a clear view of its operations without the need for blindingly bright lighting at midnight haha

I use Octoprint on a RP with Polymer on the phone, works for years now. Can work also over internet with a VPN connection. This looks like a lot of work to get it right... And be careful with the batteries of the phones, especially with the lithium polymer, a fire in your house is really possible. This type is also very popular with drone owners and has already caused quite a bit of trouble.
