First prize to this man.. .:thumsup:
For 8' your into 25mm screws minimum and has clive says motors & drives to match. Thou Charlie you are familiar with the motor/drives already as they are the Nema 34 and high power Kinco type you are using now.
What you can do to help ease screw whip is use higher lead on the screws and put ratio on them. So say 20mm pitch with 2:1 will give you same feedrate as 10mm pitch but with half the RPM on screw so helping to eliminate whip etc.
If for wood use then 25mm screws with 25mm lead and 2:1 ratio would work well as it will give decent feedrate/resolution for wood and suit slower spinning nema 34 motors better.
