OSR2+ pitch movement at bottom despite static pitch value

[MichaelLM]

Dear Fain,

You cannot believe how glad I am for your work (and pointing me to platform.io). Thank you very much. I have learned a lot thanks to your input.
When I set SR6 mode to false is the code then optimized for OSR2+?
The reason I ask is that despite the pitch value being static I have a pitch movement at the bottom/ end of down movement. (More than for just keeping the up down axis aligned)?

TcodeESP32 0.258b set to Tcode V1
Multifunplayer 1.24.0.0 (but same on joyfunplayer)
OSR2+ https://discuss.eroscripts.com/t/osr2-work-in-progress/40027/15
ESP8266 DOIT DEV Kit V1

I have designed the arms myself to make them compatible to ball head joints (yes a possible failure) and would like to go further with my improved design. Could this be a geometry failure. They should be as close as possible to the original.
In case I can help with documentation or CAD, 3D Print you are very welcome to reach out to me. Any creative ideas I am your man to contact. :-)
Some more details/documentation to the user settings (in a separate PDF to reduce sketch size) would be a huge help for newcomers.

Best regards,
Michael

I'm not sure what you mean with this but the pitch acting weird like this (I think) can be the firmware is running SR6 mode on OSR hardware.
