Hi Clive,

I was playing around with the stepper calculator from this forum...

1605 on Z 1:1 ? or also reducted?


Picking the 2010 over a 1610 on x axis ,1700mm between bearings, is about critical rpm vs speed... looks like i need 2010 to reach up to or over 5 m/min.

What is your opinion on these?

Since i am a beginner i am not sure what the max speed is i would need for cutting and rappids

Some other materials might need faster speeds i am not sure...


2.2kw spindle makes cutting at lower rpm easier combined with a quality vfd.

I am trying to pick the right quality parts to make a versatile machine.

Any help is welcome.

Please share your concerns.

No linear parts or elektronics are bought yet.
