I have both an Ender 3 V3 SE and the Hi Combo
I have both an Ender 3 V3 SE and the HI Combo. Both are excellent machines that perform exceedingly well. I use the Ender for "small jobs" and the Hi for multi-color and/or making items that require a bigger footprint, a long time to print or filament changes. As to slicer SW, I use Creality 6.2 because of it's full integration with my Hi and also the many features specific to Creality products not found in other slicers. Finally, customer support is excellent. I had a problem with the filament buffer for my Hi. When I could not resolve the problem using the Wiki links and videos, Creality sent me a new buffer to address the problem. You really can't ask for better than that.
