@dadoblu_2000 one other piece of advice: consider whether it might be better to install a Duet 3 Mini instead of a Duet 2. The Duet 3 boards already support some features that Duet 2 doesn't, and this list will grow in future because of limited memory on Duet 2. The main reason for using Duet 2 would be if the stepper motors need more current than the Duet 3 Mini can comfortably supply. If you can identify the stepper motor model numbers on your Ultimaker, we can look up the rated current and determine whether Duet 3 Mini would be suitable.
