    Hi,

    I would like to build a 1500 mm Y-axis, a 1000 mm X-axis, and a 250 mm Z-axis. However, I have a question
    regarding the belt and pinion vs using the C-Beam solution.

    Belt and Pinon
    How stable is the belt when cutting aluminum parts?
    How likely is it to jump tooth positions?
    What is the fastest achievable linear inches/second?
    Does the belt stretch?
    How likely is it to skip steps?

    C-Beam
    How stable is the C-Beam when cutting aluminum parts?
    How likely is it to skip steps?
    What is the fastest achievable linear inches/second?

    I am currently considering using the belt and pinion solution for the Y-axis and the C-beam solution for the X-axis and Z-axis. Can someone please help me with a recommendation?

    Which would you recommend as a linear solution for the X – Y axis to cut aluminum, plastic, and wooden parts?

    If your intent is to cut aluminum then you need a C-beam/screw based machine.
    While an OX 'can' cut aluminum, the belts are not the best thing for that, and you need more stiffness.
    Have a look at the design @Moag is working on for a larger C-Beam Machine if you need more than a 12x12" work area.

    I am building a 1000mm x 1000mm C-BEAM style for that very reason.
