Can you share the config.g file instead please? The config.json is generated from the RRF config tool and then not adjusted again.
Can you also supply your homeall, homex, homey and homez files?

homez.g homey.g homex.g homeall.g config.g

@printingmark if it’s not homing to the right place, are you sure your Endstops are plugged in correctly? Sounds like X and Y may be swapped.

@printingmark Mark, I would suggest that you look at the following

M566 X1200.00 Y1200.00 Z24.00 E300.00 ; set maximum instantaneous speed changes (mm/min)
M203 X30000.00 Y30000.00 Z300.00 E1500.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E5000.00 ; set accelerations (mm/s^2)

I beg anyone to please insure that I am giving the correct information and help for him. I am very new the REPRAP Firmware. Mark, please change that code listed above thats in your config.g file to the following

M566 X600.00 Y600.00 Z12.00 E150.00 ; set maximum instantaneous speed changes (mm/min)
M203 X3000.00 Y3000.00 Z30.00 E150.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E500.00 ; set accelerations (mm/s^2)

The way you described your problem makes me feel like your stepper motors are skipping big time. I had this very same issue and I had to basically lower all those values down to almost nothing. After changing those valves listed above, my printer started to work like a champ. Produced some nice prints.

I own a Tevo Black Widow. I know you said you own an Ender 3. Those numbers I listed above for you to change will not hurt anything at all. But you can play with them so they fit your printer. I am only suggesting those numbers as a guideline to start at.

Keep us posted on your success.
