    MPG - manual pulse generator. Handheld controller, pendant, or somesuch. My router doesn't have handwheels and I don't bother on my mill either. Wireless mpg or MDI on controller does the job. It's easier than folding out the handles on the handwheels and quicker as well - I can't wind by hand that fast!

    I've got some Lichuan Nema 24 5.5Nm 2 phase closed loop with 70V AC or 100Vdc drives with 3Mtr cables which I'm offering to Forum members. £125.00 plus postage.

    Also got some Closed loop 10Nm 3 phase Nema 34's using Mains voltage drives but those might be a little too large and expensive.
    These are great for large machines where high speed isn't required and simplicity is prefered to more complicated servo's. The motors are nice and smooth being 3 phase and with being mains drives they still spin at resonable rate with good torque at higher rpm's. The closed loop makes them nice and reliable in position terms.

    If you don't require what Servo's offer then they are good option and pretty much plug n play with no messing around tuning etc.

    Hi @JAZZCNC,

    Might be an odd question, but with the 220V drives do you find it necessary to step the incoming voltage down to suit? Interested in trying out some 34's in the 10-12 range and just looking to see how others have done it - assuming 30A supply single phase?

    Thanks.

    Apologies for the hijack, just wondering if it's necessary to step down the mains voltage for the 220V drivers?
