Anycubic i3 Mega

I have a spare 8 bit Trigorilla board that came from an AnyCubic i3 Mega S (I believe it's what people call version "03") that I've been playing around with, and although I have been able to easily find all the pinouts for the board (5V/12V connections, data pins, ground pins, etc) I have not been able to find any information on how much current I can safely draw from the various pins. I found some information about the fan headers, but I'm more interested in the servo pins, limit switches, and the 12V connection on the "IIC" header. I'm trying to do some custom stuff. Anyone have any idea?

Thanks,

Hello everybody!
The right 2-pin fan connector at the hotend on my I3Ms stopped working. Both fans work if plugged into the left connector, so fans work just fine.
I started 3dprinting half a year ago and love it, but I really don't have any idea on how to fix the shown connector, as it looks well and intact. Does anyone know how to troubleshoot the problem, fix the connector or where to purchase a new/better? I'm decently handy, but I don't have a soldering kit. Any and all help is highly appreciated!

My SD card wont read any files n my i3, I have checked the ribbon connectors and re-set the device, any ideas? I have also tried a new SD card and some old ones...

Can anyone help? My prints were not sticking to my base, so I flashed the firmware with the latest Marlin and mesh levelled the base. Now not only is the filament not sticking, the printer is under extruding. All of the instructions online require being able to see the gcode reponse from the printer. I only have Cura which doesn't show this. The octaprint installation is beyond me and I can't find any understandable tutorials, I get as far as downloading xcode then I'm lost. I'm about to give up completely after two years of great prints. I have an Anycubic Mega S, I swapped the hot end (so that is new). Thanks
