I purchased this Rotary Pro after seeing a few reviews talking about how the regular Rotary seems to miss some steps because of how the part rotates.I have been pretty pleased with the performance of the Rotary Pro. The one thing I wish Creality would do is make a cut out in the base under where the cable needs to plug in. It was fairly difficult getting it inserted into the Rotary with the limited space provided. But, now that it is plugged in, I do not plan to unplug it again so hopefully that is a one time issue. Still it would be nice if the cut out were there, so that I could easily unplug and plug it back in so I could store it without the cable attached.
