OEM Board - SKR Mini e3 - BLTouch

Why in the world is the OEM Board so much easier to get BL Touch going? Lol... I have two printers im messing with right now.... one has OEM Board the other has a SKR Mini e3 v1.2. I installed the BL Touch on to the OEM board, hooked up the provided USB thing clicked this clicked that and bam done. But, with this skr mini I have having way more difficulties setting it up. I have it all plugged in and now I'm just trying to get like a hex file I think or something onto the printer but their is no simple guild of just do this and that... which is kinda fine I don't expect everything to be handed to me, but you'd think with a newer item / more updated it would be even easier to set up and get going.. #rantover
