octo4a only connects to printer with usb cable connected and OTG cable connected to tablet.

[clear cobalt]

Having a power issue with the tablet that is running octoprint, OTG cable connected to the TABLET will establish a connection with the printer, but will not charge it!

yeah you shouldnt charge your tablet through your printer...

you need a stronger power source.

[clear cobalt]

no no im not charging THROUGH the printer

[clear cobalt]

ok so heres how the entire thing is working

Power brick > microusb cable > OTG cable ---- USB = TABLET
I--- micro usb cable to printer

WORKS. without charging

Power brick > microusb cable > OTG cable ---- USB = cable to PRINTER
I--- micro usb cable TABLET

doesnt work, establishes charge however, no connection to printer

sounds like maybe your otg cable doesnt have the data pins on it

[clear cobalt]

could something like this work?? https://www.amazon.ca/Splitter-Adapter-Converter-Android-Samsung/dp/B00OZDUTMM/ref=sr_1_2_sspa?keywords=otg+cable+micro+usb&qid=1669515454&qu=eyJxc2MiOiIzLjQ3IiwicXNhIjoiMy4wNyIsInFzcCI6IjIuNzUifQ%3D%3D&sprefix=otg+cable+mi%2Caps%2C84&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyQTFQQlFOSjQ4NVZMJmVuY3J5cHRlZElkPUEwNTUyODgwMUk2RlpSNzhXWlFXRiZlbmNyeXB0ZWRBZElkPUEwNDM2MDc3MjhDRVpKWTROVzlLVSZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

might be overkill

but a hub could supply the power AND have data pins?

[cloud mural]

no... you need to have a splitter.. split the 4 usb pins to the two power pins black and red... and the 2 data pins go to the printer white and green

[clear cobalt]

uhhh

i did not understand

[cloud mural]

usb cable has four wires in it... red white green and black... red and black supply power... green and white are the data

[clear cobalt]

ok

makes sense so far

[cloud mural]

does the tablet only have the one usb?

[clear cobalt]

tablet only has 1 microusb slot

no usb sadly

[cloud mural]

kk.. i would take a micro usb cable... and strip the wires... then take the printer usb and strip that... and the power usb strip that... black and red go to power.. white and green go to data

[clear cobalt]

ok so theres 4 wires from each cable (3 cables)

[cloud mural]

yup

[clear cobalt]

so i connect the tablet to the power brick

but in your case

you want me to cut the green and white cable

and connect that to the printer

[cloud mural]

this might be too much for you

[clear cobalt]

i understand it but i cant say it right

[cloud mural]

you are essentially making a Y cable

[clear cobalt]

yeah i get it

is there a safer method?

i am playing with electricity here

[cloud mural]

could probably buy a cable...

[clear cobalt]

id rather do that yeah

so a 3 way micro usb connection?

would a single data and charge and a charge variant work?

[cloud mural]

no cuz you dont want the power to feed from the printer to the tablet

itll drain the printer

[clear cobalt]

would that fit?

im confused

[cloud mural]

you said micro usb

hang on

yeah im not seeing what you need on amazon

[clear cobalt]

welp

there might be an alternative way

what if i could split the charging port on the tablet?

[cloud mural]

thats what i was trying to say but i dont want to be responsible for the failure

[clear cobalt]

no no i mean with an cable

[cloud mural]

i dont think so

https://www.amazon.com/Splitter-Adapter-Headphone-Charger-Charging/dp/B09WHMMJDP/ref=asc_df_B09WHMMJDP/?tag=hyprod-20&linkCode=df0&hvadid=598342985678&hvpos=&hvnetw=g&hvrand=9909517357706825753&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9016918&hvtargid=pla-1726891188411&psc=1

maybe something like this

[clear cobalt]

but thats usb c oof

imma be honest i feel like your method is the only possible way

[cloud mural]

might be your tablet though.. shuts off data while charging

[clear cobalt]

i mean i am making a video on this

i dont wanna like encourage power hijacking

[cloud mural]

its not power hijacking

[clear cobalt]

its the other way, it gives data, but no charge

and thats with the correct way of using the OTG Y splitter Cable to the tablet

the only way left is a 30 feet Microusb cord

going from my computer to the printer in the basement

hmm well

what if i used my modem/router for this fix?

argh well even if i did that all the money i spent on the phone holder and cables would be a waste

[clear cobalt]

Just to make sure we understand it, this is the charging configuration

And this is the data configuration

Both supply power to printer

[clear cobalt]

ok so @cloud mural turns out its just the tablet, i tried it on my moms older phone temp, it worked perfectly with data and charging!

possible hypothesis, larger screen = more energy, therefore energy spent =/= to energy gained

[odd lily]

I bought a cable thst said it could charge and send data like that but didn't I think it doesn't work they way it sounds like it should I ened up using the wireless charging feature on my old phone instead

[frail ridge]

I made my Octoprint from a raspberry pi

4

[clear cobalt]

oh wow why didnt i think of that?

OH wait its because a rasberry pi is 200 dollars
