Hotend wiring pinout for Geeetech A30 pro?

[cristineg]

Hello.

I recently got a geeetech a30 pro and want to replace the board with an SKR 1.3, as the marlin firmware examples for the printer are not complete and cannot be built for this printer's GTM30 board.

I'm extremely familiar with the SKR 1.3, and have installed them on two printers before, along with heavily customizing marlin for it.

I've easily identified every cable going into the motherboard, except for the hotend, which uses a custom breakout board.

I can't seem to find a pinout diagram that I can follow. Failing being able to find that (even with someone's help), what's the best way of identifying each wire?

I know I can use a multimeter, but I'm not an expert with using it. Perhaps I could pull out one individual wire at a time and see what stops working?

To summarize, ideally, someone with better searching skills than I would be able to provide me with a pinout (ideally color coded to match the wires), or alternatively, advice on identifying the individual wires myself.

Thank you.

I truly like your tremendous help with the board updates, these are useful. The people who need the machine parts they should grab from the company directly. Your blogging the best dissertation writing services updates are useful and that information would works to all keep it up.
