Plus longer term, may also add some sort of flood / spray cooling when cutting larger metal jobs in Alu. but may also go further if my machine can handle it! or even upgrade some bits later.

I have the bed / stage XYZ all working and homing correctly now and only now need a spindle.

Thanks

Hi Paul, the 2.2kw would be fine for cutting all your types Wood Aluminium etc I have used it on all including sandstone and granite no problem but if you do get into stone, slate you will need to think of flood water coolant to the cutter or you are going to burn out the cutter quick.

On the first a larger cnc for cutting all stone/ granite many years ago we put a 4KW spindle which I got from Damon cnc in Germany a lot more money but that has been running I guess for 15 years 24/7 a lot of the time and I have changed a set of bearing in it.
