Wow, thanks. At least I can see pin assignments now, unfortunately, I had tried the E0 line for enabling heat fan to come on above 50 degrees and it just didn't work for some reason. I have a MKS GEN L board coming with the ATMEGA 2560 onboard and I think I am just going to use that and if it works, I'll be sending the MKS SGEN_L board back because this is just a headache for me with the issues I am having, mostly my EZABL not working on Z_MIN or Z_MAX. Banging my head on my desk over here lol. I really don't care to be up until 3am again tonight.

You sure the stepper modules are in correctly?
with mks the pins are color coded black to black and green to green

You need to set #define SERIAL_PORT -1
-1 means use the usb port for serial communications.

So to update anyone curious.
Marlin 2.0 release on 1 Dec 2019.
So far I have motor movement. I have sensorless homing working on the x and y axis. The y axis though seems hit or miss but the fact that others have stated they couldn't get it to work on this setup just makes me keep pushing.
To reiterate:
I am using the MKS SGEN-L 32 bit with the bundled MKS TMC2209 V1.0 drivers. Marlin 2.0 works on the board and the sensorless homing can at least be achieved on this bundle. Now I believe I have to tune my currents and speeds to get my y axis homing to be more reliable.
EDIT:
It was a good struggle but I have succeeded. Sensorless homing on MKS SGEN-L with MKS TMC2209 v1.

Hi,
could you elaborate how you got sensorless homing working. Ik have the sgen-l with mks tmc2209 drivers. I compiled Marlin 2.0 firmware with senorless homing enabled, but I am not getting any movent on homing.

I will take a stab at possible issues.
Send M119 and check your endstop status before attempting homing. I'm guessing they will be TRIGGERED.
If they are triggered, using your hand move your axis to your home position (perferrably x or y for safe testing) and send G92 X0 or G92 Y0 depending on which axis you are testing.
After G92 command send G0 X25 F1000 or G0 Y25 F1000 depending on your axis. If you have movement then you're good. If you don't have movement you have to check your board setup, maybe jumpers aren't set right or other issues.

ok, that's the middle one in the 'triangle' right?
edit: Ok, confirmed, it was the 'middle' one. I have it working now. Thanks for your help!

Good to hear.
It's best to find the stallguard threshold value that causes instant endstop trigger and then drop it by 5 to try to keep a reliable homing setup.
Also, if you change your speeds in marlin (or from the lcd controller) test homing again. The sensorless homing is very dependant on the homing speed.
