So I've had other work related things keeping from the ability to work on this problem much for a while. I did however during that time manage to print some new belt tensioner options that work very well. I now have consistent belt tension on all three belts and it is easily adjustable. Right now each is set to ~1lbs 3oz measured at 1" deflection from the tower at the halfway point from top to bottom of the tower.
I've checked the alignment of the towers once again and somehow they're farther off now than they were before. At this point I'm guessing attributed to environmental changes. It goes down to 18C in that room overnight, but during the day with people it runs around 22-24C. Also moisture has gone from 70%RH to 47%RH in the last month. So as of now the towers are very close to 90degrees to the bed. As in I can't slip a sheet of paper in between the square and the tower, but I can see a bit of a gap.
Measurements between the towers at the top and bottom were taken with a 6" caliper using the head to tail methods so they are not absolute measure, but simply relative between each tower. The X-Y bottom: 80.97, top 81.04. Y-Z bottom: 80.13, top: 80.93. Y-Z bottom: 80.24, top: 81.11.
(all measuring etc done with bed@60C)
This is this morning G32 with S-1 before adjustments with 0 offset in the bed.g
Bed probe heights: 0.103 -0.007 0.162 -0.007 -0.057 0.151 0.015 -0.022 0.115 0.020 0.010 0.039 0.011 0.117 0.062 -0.020, mean 0.043, deviation from mean 0.065
I just reran through the "Adding trigger height to bed.g" steps and calculated all the offsets and placed them in my bed.g.
Bed probe heights: -0.017 0.161 0.475 0.368 0.028 0.006 -0.258 -0.232 -0.142 -0.032 0.165 0.191 -0.004 -0.035 -0.136 -0.008, mean 0.033, deviation from mean 0.193
Then G32 with S6 x3
Calibrated 6 factors using 16 points, deviation before 0.197 after 0.052
Calibrated 6 factors using 16 points, deviation before 0.055 after 0.055
Calibrated 6 factors using 16 points, deviation before 0.051 after 0.051
Then I switch back to no offsets (because it was better before) and I get worse results for S-1
Bed probe heights: 0.174 0.022 0.355 0.301 0.210 -0.024 -0.090 0.017 0.015 0.004 0.263 0.186 0.048 0.001 -0.097 -0.128, mean 0.079, deviation from mean 0.144
S6
Calibrated 6 factors using 16 points, deviation before 0.168 after 0.072
Cycled power, now no offsets S-1
Bed probe heights: 0.099 -0.003 0.342 0.339 0.235 0.176 -0.002 -0.070 0.040 0.004 0.126 0.211 0.123 0.101 -0.010 0.009, mean 0.107, deviation from mean 0.121
S6 x2
Calibrated 6 factors using 16 points, deviation before 0.160 after 0.054
Calibrated 6 factors using 16 points, deviation before 0.055 after 0.055

M666
Endstop adjustments X-0.18 Y-0.20 Z0.38, tilt X0.27% Y0.19%
And printing a 75mm diameter single layer test disk comes out pretty bad looking still.
I have no clue what else to adjust, what else to modify etc. I've locked everything down mechanically that I can possibly think of and is possible with the melamine frame.
