My lathe was relatively cheap, and suffers from a large amount of backlash on both axis. This was fine when I was only using it manually, but it does suffer now it is CNC.

Can anybody tell me where to get new leadscrews etc - preferably ball screws in the UK.

My lathe is a large Warco.

I know Marchant Dice sell them, what prices are like I dont know as I have never bought new ballscrews other than from eBay.

Motion Controlled Products are also selling them not as big a range as Marchant Dice but the ball nuts are cheaper

After a disastrous start into the word of CNC i am also using the drivers and power supply's from them and they are awesome.

Thanks for the replies - plenty to go at there !!!

 www.arceurotrade.co.uk also has ball screws now but think they only go up to about 16mm Dia

Yes - the lead screw is 20mm, and I don't think I want to go below that - I'm trying to get a bit more speed out of it, as well as get rid of backlash.  It would do for the cross slide, however, that is thinner.

Phil H's Motion Control site looked promising. I have an engine to finish for a customer before Easter then I will have a serious look at it.
