Reddit reviews Quimat 3D Printer Controller Kit for Arduino Mega 2560 Starter Kits + RAMPS 1.4 with Upgraded Mosfet + 5pcs A4988 Stepper Motor Driver + LCD 12864 for Arduino Reprap (Old Version)

The heatsink was on it, I removed it after I saw the back of the board and figured that's where the issue was. I purchased this (Quimat QK17 3D Printer Kit 5pcs A4988 Stepper Motor Driver with Heatsink + Controller RAMPS 1.4 +LCD 12864 Graphic Smart Display Controller with Adapter + Mega 2560 R3 For Arduino RepRap https://www.amazon.com/dp/B01C2IHYBA/ref=cm_sw_r_cp_api_toDlxbGQEKV81) to replace it since the melzi board was $85, but I have no idea what I'm doing with it quite frankly. I've built and repaired computers and phones, but this is a bit more complex. I'm sure I can learn how to do it, but have no idea where to start since instructions one making THAT board work with the exact parts and wires I have, I can't seem to find.

I picked up the Wanhao with the understanding that I would end up having to rebuild it at some point, and by doing so I would hopefully learn something about how they work. It just happened to break when I've got some interesting stuff to print.

That Melzi board has never worked right from the start. It had a weird temperature fluctuation issue related to a bad ground, which Wanhao refused to warranty. I fixed the ground and replaced the hotend with the microswiss hotend and it worked beautifully for 2 weeks. I guess the Florida heat and the added stress of printing petg at 240c did it in.

I'm considering going with a ramps control board like this one due to the low cost. Is there anything that i should be specifically looking for when buying a control board? Thanks for your help with all this.
