Thanks for your quick reply. It is encouraging that you have 18 months + use. I am currently machining the ball screw housings on my Arboga mill, modelled in Fusion and test printed on my 3D printer for fit. Using cast iron for housings (because I have some). If you were to start again, what would you do differently?

Thank you for your post which motivated me to buy the SX2.7 and modify it. I now have a neat lockdown project!

Thanks again and stay safe
