Okay I will begin by listing hardware, software, and firmware data.
I am running the Duet 3 6HC mainboard, and it is running in SBC mode with a 4GB Raspberry Pi 4. I use an ethernet cable for comms and the Duet Web Control for controlling the board.
Up till now I have run config files generated by the old RRF tool with some modification. And then recently I decided I would add a poor man's BL touch, so I figured I would switch and use the new RRF tool.
Right off I started setting up the optical sensor for the poor man's bltouch and got it working, but when I went to home my X and Y it acted like the end-stops were already triggered so I tried changing the S1 in the config.g in the end-stop section to S0 but it said the S0 value is invalid so I put it back to S1 and tried rewiring my end-stops using every possible combination and no luck. So I switched out my end-stops for optical triggers and rigged up flags. That worked. Is there an explanation for the other end-stops?
Next, the servo motor I am using for the poor man's bltouch buzzes, jumps up and down and gets hot when I go to print is it just the servo motor or is it something I got wrong in setup?
Here is config.g the RRF tool v3.5.0-rc.3+2 please note that this config file is unmodified and the reason it is different in the Esteps and driver mapping is because I could set those up in the new tool but not in the old, and would have to modify them manually.

Thank you for looking and if anyone has any pointers I would be grateful. Let me know if you need anything or if something is unclear, I am exhausted and I don't know what I miss. Thanks in advance, Shawn
