    Easy Q - wiring/connectors to buy for driver, motors etc.

    I am ordering parts to put together a CNC machine...

    I plan on going with the MASSO (link below) and a 4 axis NEMA 34 motor, power supply and driver kit.
    I will follow the directions for wiring instructions BUT

    Here is the question....

    ***How do I decide which wiring to buy and which connectors?***

    Masso: https://www.masso.com.au/product/mil...controller-g3/
    NEMA 34 Kit: 4 Axis CNC Kit 1841oz.in Nema 34 Stepper Motor 5A 86x150mm & Stepper Driver 705701863663 | eBay

    I am always interested in other perspectives on if I'm heading in the right direction with the stuff I am buying. Purchased a 3x5 CNC from CNC router parts. Its up to me for all the electronics etc. Just for hobby. Still looking at spindles.

    The link to the motors is bad.

    I mean the link doesn't work. I can't comment on the motors if I don't know what they are.

    Okay, it looks like this kit?
    https://www.ebay.com/itm/4-Axis-CNC-...-/333450858092


    Do NOT buy this kit. Small Nema 23 motors would easily outperform these large motors. Bigger is NOT better.

    What you want is a stepper in the 650oz-in range, rated at 6 amps and an inductance rating around 2mH, and run them at 60V-70V. And good drives like Leadshine EM806's.

    Those cheap ebay kits with huge motors are complete garbage.

    Thank you! I think I can still cancel my order. Thats what I needed... a point in the right direction. I imagine closed loop would be best? Even if it is just for hobby it will lead to less errors on large projects?

    I'm not a fan of closed loop steppers.
    A properly setup open loop system should be 100% accurate.
