Yes, I used the M280 commands to determine to correct angles. Uploaded the changes and then used the m401 and m402 commands to check. I even did a g28 and g29 to confirm. All work well.

The next time I fired up the machine the servo angles are wonky.

Try testing with this, making sure the probe ends up where you expect

M401 - deploys the probe
M402 - retracts the probe
