changing wifi setting in raspberry pi.

hi all, i posted this in the klipper discord, but haven't heard anything yet. hello all, i recently had to factory reset my router. i put in the same ssid and pw settings but i lost my pi. i checked the ratos-wpa-supplicant on the sd card, but it does have the right ssid and pw. ALTHOUGH pw is # in front of it and below it has another psk that is not #, and it has a very long alpha numeric string ( maybe 50 characters ). So question is, is there a solution in the wpa supplicant, or will i have to get a keyboard and monitor on the rasp pi and get into it. Which leads me to this. i did do that and the boot up sequence looks good, but it will auto load klipper. how do i stop that or get out of klipper, back into the command prompt screen? i can't control anything once in klipper. no keyboard commands help me navigate. i move a mouse and start clicking but what it selects is pretty random.

Z homing issue

i'm back 😦 when i try to Z home from klipper, the front left stepper goes downwards, while the right and rear goes upwards. If i dont emergency stop on time, the bed will fall off from the tilt angle. You'd think it's a motor with reversed wiring but when i select x and y homing, the bed will lower an inch with no problems. All 3 motors go down the same amount. Any suggestions?
vcore 3 - 500 stock steppers from ratrig btt skr pro 1.2 bltouch klippers and mainsail thanks

specific printer.cfg for btt skr pro 1.2 ( not the generic one)

HI all, long story short, i blew a skr pro rail when i put the filament sensor plugs the wrong way vs the ones that came with the vcore 3.0 (different limit switches ), so i gave up for over a year. Now i'm back. I hooked up the new board ( same model ) plugged in everything except the filament limit switch ( too chicken for now ). I followed Ed's 3d tech video ( https://youtu.be/jAPedRDj5S0?si=K3uyzXc2Pz4TjcvF) and it was a big help although i'm doing klipper and mainsail ( not octoprint ). I got it installed on the Pi, flashed the pro ( following his instructions ), but it seems to me that the printer.cfg file that the moonsail is using is the generic-bigtree-skr-pro-1.2 found under klipper/config folder on the pi sd card ( using filezilla to see the folder structure ). This printer config obviously has no ratrig vcore 3.0 500 specific settings in it that i can work with to change the values to my specific set up. I watched Teaching Tech's The Rat Rig v-core 3 build gets serious! Part 3: Wiring, Klipper setup and first print ( https://youtu.be/8B12D_D1i0s?si=kdGT6dnRG-RQkTzO ) and he has a printer.cfg that has all of the presets made for my printer and board. Where can i get that specific printer.cfg, and the relevant .cfg files that i would need which would be called up by printer.cfg? Also, where would i put those files (like the specific hemera.cfg file ) in the current folder structure of the raspberry pi klipper install where the printer.cfg can call it up? After typing this, it got me thinking, if i use the ratos set up that teaching tech used and install it on an sd card, maybe i could pull the printer.cfg, and other .cfg's off of that and transfer it over, and i could also use it's folder structure and just edit the MCU and i should be good to go? maybe? my set up is vcore 500 with their stepper motors e3d revo hemera xs bl touch adxl345 thanks for any help. i'm a windows guy, so the linux/raspberry pi OS structures are foreign to me.
