@Veti thank you that worked like a charm.

ok so far i have both z's working in tandem on z1 and e0. I can do a true level and a mesh level. What else could i do to ensure the bed is as level as possible via the dual z setup on the board? i swear i saw an walkthrough last night that talked about probing at the lead screws and syncing them up some how.
-
now you need to find the lead screw position in x and y coordinates
in the example
the first is a position x-20 y0
the second is x220 y0
M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axisthen you need to create the bed file and put in a position close to the leadscrews that you can probe on the bed
in this example we choose X20 Y0 for the first and X180 Y0 for the second
bed.gG28 ; home
G30 P0 X20 Y0 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X180 Y0 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors -
ok just so i get this right and not piss my self off. i measure with calipers from the lead screw to the probe? Or the nozzle? i havent had enough coffee or calm sanity from having to also teach my 2nd grader since schools are not "open" in our area yet.
-
from the nozzle.
the nozzle is the point of reference
-
ok this is what i got and filled in the areas. On the left side lead screw i have a measurement of 154.3mm from lead screw to nozzle. And on the right side i have a measurement of 89mm from lead screw to nozzle. and since i have the nozzle lined up on both lead screws i took those measurements and added on the right and subtracted on the left. If i did this wrong let me know.

G30 P1 X330 Y192 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors -
now give it a try and run G32.

i did and its working wonderfully thank you so much for the help and understanding. right now im printing extra parts just so i dont have to go through this entire process again if a print decides to break my bltouch mount and force me to use a fan and bltouch mount that removes the x axis switch.
-
you can even print a bltouch replacement. https://www.thingiverse.com/thing:3303618
