You need closed loop drivers and motors for that.
Not possible with open loop.
If your motors are dual shaft you could fit encoders and get new drives but personally I would ditch Nema 34 size and drop down to 24 size motors while you're at it.
They'll be a lot quieter.
I've noticed you are on mycncuk and it lists ayou as in uk.
If that's so.... Shoot Dean (Jazzcnc) a msg on there about the Lichuan LCH2102's and LCD86's
But.......... If you are a serious machiner and do a lot of stuff....... Go for servo's with A2 / A4 drives
