I don’t think it can not, at least I haven’t found a way to do it, but at some point in the future it might be nice to be able to zoom in on the preview in CM. I love that it is that. I’ve been able to save a lot of mistakes as a result.
Sometime, though, cutting small items it would help to be able to zoom in on them.
If you need to zoom in/out, I would recommend using Carbide Create’s toolpath preview — you can turn off viewing the stock and get much the same appearance as in CM.
I agree with the CC zoom and it is really great.
I also love the preview in CM.
But, if the object is small, the preview in CM, while could be very helpful, is not if you can’t zoom in to “second proof” your work.
At a guess, the consideration here is whether or no a Raspberry Pi 4, which is the lowest-common-denominator for computers running Carbide Motion could manage this sort of interface reasonably well.
