I understand the attraction of the import K40-style and Red Sail laser cutters, especially for folks that have some technical knowledge. I could probably muddle through with one of those, but am at that point in life where I'd rather be working on other projects than tweaking and tuning a laser cutter. I've seen lot of folks that tried this approach and don't have a useful tool months down the road. That's one of the reasons I opted for a mostly turnkey CNC lathe and mill, and 3D printer, though each was more than the DIY versions would have been. CNC-ing my surface grinder is still on my to-do list and that is 8 years after the thought 1st presented itself. A number of pre-order buyers have already started discussing hacks for the GF and I'll probably try that sort of thing myself.
I'm hoping that the GF will be relatively painless to use, though that remains to be seen. It appears that they will still have a few software features to implement after the initial release but the basic run of the mill stuff should be functional. One advantage of the cloud-based control system is that updates get distributed pretty much immediately. That's nice, but I'd rather have perpetually licensed software that runs from my HD, especially in a case like this with a new manufacturer that could disappear over night.
The next month or so should prove whether or not this was a waste of time. If they don't release by then they will lose a number of their pre-orders, especially if the FSL Muse is any good.
