    Hi sfallan,

    Great news, well done. A fresh windows install, followed by only adding vital software is never a bad thing where Mach3 is concerned.

    If the leadscrews are ballscrews then you need a piece of tube to roll the ballnut onto when you remove the thread, otherwise the ball bearings will fall out. If they are ACME threads with nuts (e.g. Delrin) then you are OK. To remove these you just need some basic tools, and from post #1 it looks straightforward. When you buy the new leadscrew, the end will need machining to match the bearings and motor coupling. You'll see this when you remove the old one.

    If you are not sure, strip the leadscrew out and post a photo.
