Fix issue with MMU2S not loading filament correctly (related to issue #332)

[cugnonr]

Adapted angle to fix load issue on MMU2S (lot of load failures). Since firmware rebuild with this new angle, I do not have any load issue - lot of print made using PETG with this adapted version). To test on MMU3S as I do not have such device at home.

Fixed the issue #332

See my comment in issue #332
This adaptations fixed the load issues from MMU2S (I do not got any issue with adapted firmware).
To test on MMU3S as I do not own such device at home.

Please note that I also improved my MMU2S by adding an extra power module purchased on Aliexpress
