    Hello,
    I am working on a new custom build with a 6HC board. I did my initial RRF config using the RRF config tool. Everything is working great but the tool offset doesn't appear to be changing the offset. I have a 330x330mm bed. To find the offset, I am putting painters tape all over the bed, used a straight edge from corner to corner and a marker to find the exact center of the bed (where the X crosses), then issuing "G1 X115 Y115" to have the printer go to where it thinks the center is. I have two extruders so the 2nd extruder is set up as P1. X was somewhat good but Y was way off so I set the Y offset to -80 just to see if it works and get it in the general area. When I change the offset in config.g and restart the board, and re-issue the "G1 X115 Y115" command, it goes exactly to where it was before and it appears changing the tool offset is not affecting the location of the print head. I tried changing it to 80 instead of -80 and tried putting the settings in both P0 and P1, but these didn't work. Any ideas?

    Here is my config.g file:
