    what to choose from the 2 steppers

    I'm starting to build a 6x12 cnc for woodcarving
    I oscillate between 2 stepper motors with similar characteristics
    motor A B
    holding torque 8.5 8.5
    detent torque 12.5 12.5
    resistance 0.56 0.5
    current/phase 4.2 6
    step angle 1.8 1.8
    inductance 3 2.1
    rotor inertia 2700 1800
    lead wire numbers 8 4

    I know that a stepper with lower inductance is preferable in order to be supercharged, but also the option of having 8 wires with the possibility of connecting the motor in parallel bipolar mode attracts me. which is which?
    what would you choose?

    You can use the first motor if your power supply is providing over 50v and your drivers can handle it. But these aren't the only motors in the world; if you want a stepper with 8 wires and lower inductance, keep looking.

    Awerby, do you have some cheap models in mind, i'm new in the field and any help will be apreciated. First model is SYNWELL SW-86J18118-842 and second in 86HS11860A4
