I've been using ChiTuBox 1.2.0 for a few days now, and despite a few crashes during the hollowing process, I'm enjoying it a lot. One issue I've had though is that sometimes when I resize a mesh, it will revert back to its original size without warning.
For example, I changed the size of a mesh to 110%, then hollowed and added supports. It then showed it to be at 100% size, which I figured was a result of adding the supports, or that the type-in values were relative to its current size, rather than its original size. The model printed, and my next print was a piece that would connect to the first one. It properly printed at 110% size, and only then did I find out that the first one had actually reverted to its original size.
So there may be some function along that way that caused the model to revert its scale. Until this gets addressed, I'd recommend that users double-check their scales (especially when its a small rescale, such as a 10% difference), or to resize in another program and re-save the scaled stl.
Aside from that, I'm extremely happy with this slicer - it's the best I've used to date.
