    They're all connected...your Z travel is going to be a function of your deflection (almost certainly at max Z and min/max Y). You may have a little space to decide where your Z travel starts and...

    You're forgetting that reducing the travels also reduces the moments, which reduces the deflection that drives total mass of the machine.



    This should never be about opinion, IMO. I mean you're...

    There must be some makerspaces or something in whatever borough you're in. I would start there, they probably have a mill and a lathe and a basic training course.

    OnShape is also $2k a year versus $4-500 for Fusion. If you just want 3+2 CAM and decent 3D modeling, Fusion is great. I have to reevaluate OnShape versus Solidworks in the next few months, last year...

    Look at most hobby equipment and you'll see limited or no guarding. A lot of it is just that there's virtually no power behind those motors, so injuries are going to be less serious. The other aspect...

    I spent a fair amount of money through Protolabs and Xometry at my last job (mid-five figures a year), but only because they refused to bring any real machining in house. Drove me nuts. I could not...
