Yes you have.. you liking to use software is not realy the subject and somewhat off topic. I like to use software whats your point? if want simple cuts draw simple shapes and thats free in Designer. but a table top CNC is cool two i do not realy care that much. Just sticking up for a good machine and quality software.
For me it is slow and too weak. I only use it for 2d and when I tell it to cut 1/16 I expect it to cut 1/16.
actually i read that 2 1/2 hrs is fast or faster than a table top thats ready for a quick 80 to 150 grit sand down and finish.
But sure the gantry system has some drawback but..
Regarding the vector depth you could need to calibrate the thing, mine are accurate for 59 LP inlays and the traps.
Thought I give some love now going back to my cave..
