Sonic Pad and E3 V2

I just installed a Sonic Pad to my E3-V2 with high hopes!! WHAT A DISAPPOINTMENT!! it will not level correctly, plus it is SO SLOW!!!
I printed the same model on both my v2’s and the stock printer printed it faster and CLEANER!!! The unit with the Sonic Pad was so bad I scrapped it!! What am I doing wrong!! I even read the instructions!!! and it still will not work!! Should I bother or jut send it back??

(now I can’t even get my BEST printer back to normal after removing the SP!!!)
