Might be OK, as said not a wood worker so cant say for sure, only thoughts are if moving too slow on the rotation you may burn the wood.

Robhi,

Can't speak for the others, but I am confused about exactly what your configuration is, especially what 'spindle' you refer to from one post to the next.

My impression is that you have one high speed spindle which will be the 'pen' and do the actual engraving and the second spindle is holding the workpiece and does not need to do anything other than slowly rotate the workpiece in the manner of an 'A' axis for a mill.

If the above description fits your machine, then the remaining question is how fast you need to turn the 'A' axis. If you need to go fast for wood TURNING, you need a servo. If you only need to go slow for wood ENGRAVING then a stepper would be adequate.

Hello,
thanks again for all you.

that is really what I need.

I have my forth axis. it (i guess) works well. at any rate it turns as the other axes. I have no Programme (GCode) to test it.
But I guess it must work. question is:-

how could I configure it , in order to work in degree? I mean, if I would like to turn my workpiece into 90° or 45° , or the cam will do it itself?

Hoping I am a little bit clear.

Hello,

I can not convert the step per revolution into degrees.. how could I do that?

My motor is coupled directly to the chuck..I have a normal stepper motor, as well as G201.

Forth axis works well, but it turns three or four times, more than 360°.....
thank you for your help

2000/360 will give you the step per degree.
