How to setup firmware for corexy
I've searched the forum pretty good (I think), I've found bits and pieces concerning this but nothing explaining everything at once. I've been messing around with this firmware setup sense last year and I don't think I've made much In the way of progress. My printer is x-350mm, y-427mm, z-673mm, dual extruder, and bltouch probe. I have 3 endstops mounted, x-min, y-max, z-min. I should also mention I'm running the ramps 1.4/Mega combo and my heated bed is running independent of the board. Now when I setup the firmware the first time I chose the first corexy option and I was able to get the xy motors to home but z moves ultra slow, like if i wasnt looking right at pulley and leadscrew I'd never know it was moving slow and it homes in the wrong direction. I'd love to know what I'm doing wrong here, I've been working on this sense November and its driving me nuts!

Im hoping to get this thing ready to at least make a dry print, I still have the cables from my hotends, cooling fan, and BLTouch to extend and connect.
Check your size settings too.
Share your config file and we can have a look.
these are 2 new videos showing the movement issues and below is my config.h

this is the config.h file as it sits now, its got to be something silly that i am missing

Also, maybe your belt is not tensioned properly and/or toothed pulleys on the stepper is loose. I'm thinking this is more of a hardware issue vs software.
Both z and x are working as they should be, y is still being difficult.
