Large aluminium profile build

[Clive S]

Boyan I don't know why you always insist on rotating ball nuts for this size of machine my router is 1600 x 1000
using 1610 on X and Y
I can easily get 10m/min with 2 x nema 23s the screws don't need to be as long as the table.
Although I use two motors many people use one nema 34 with a belt connecting the screws.

-you will need that 2m straight edge, 50cm square, 30cm square, 10cm square. / read my second build log why/

Very few people have a 2 mtr straight edge and still get perfect good machines just have a look around the forum.

• iv’e seen some threads in which the Z axis was designed in a way that the bearing carriages are stationary and the rails move with the spindle - could anyone point clear this up or point me to the right thread?

One of the reasons for this, ie putting the rails on the spindle plate is that it stiffens the plate up
