Need some help with a new SIEG SX2 Plus CNC Conversion

[Clive S]

All i need now are the motors, drivers, ball screws and ball screw brackets.
Any advice on this part ?

If you do a search on here there has been a few conversions done. This company makes a kit:- http://www.cncfusion.com/minimill1.html Also there is a thread here :-http://www.mycncuk.com/threads/4524-...us-build/page4. .. Clive

i picked up a used clone a few weeks ago to do basic jobs but have done quite a bit of research on them all. It looks like you have the one with the upgraded spindle motor and a belt drive up grade which i think is the first mod people do. The good thing about yours is the fixed base as this is a little more solid than the adjustable one however a lot of people seam to go for building a hole new steel frame to bolt the base and the column to to get it even more stable. there is a good thread here about it and is what i plan to do

youtube has lots of cnc conversions and as mentioned there is a kit from cnc fusion which uses ball screws all round. Again i have been looking into ball screws but ideally you want one with a small ball nut which i have not found yet.

another common mod is to use ether a gas strut or counter weight on the z axis.
