But you should be using 8 / 10 mirco stepping for best performance of the motors and why are you worried about the interger as it is a cnc'd machine that will be controlling it.

As before i have done it with this machine, 0.001 res is pie in the sky, £200,000 machine tool struggle to get that with direct drive and servo's. 0.025 per step is what i run and gives me 1500mm/min rapid you would be lucky to get 700mm/min as you would be over spinning the motor and have not torque.

resolution and power work againest each other.

here a like to my Thread on cnc zone.

Ok Hi There fragger, the steppers two x 23 & 1 x 34 from motionking, the 'integer' is for me, not the software, I design what would end up on the machine in the first place as i said "This is an odd measurement to use in my head" Now as for accuracy, wouldnt you say, that aiming for the highest accuracy you can in the begining is the correct thing to do.

I would never suggest I would get that resolution at the end of the project but if i allow the push for accuracy to become secondary to simplicity of build i would not be true to myself, and speed/feedrate well this is a hobby for me, im not in a hurry, im still one of those sad individuals that likes to sit there and watch, and i know im not the only one AM I???

Would i not get more torque with a 2.5:1 setup then?

I have read with interest the posts about this machine type on cnczone.

Pulleys are the way i would like to go as i dont like the positioning of the steppers in the other projects I have seen, they may be fine for you and make the conversion simple and speedy but that is not what im after, I have learned a lot from the conversions on cnczone but they just dont fit my requirements.

Stevie Nicks and her famous song told me all i needed to know lol

I do like the way you have mounted your x axis ballnut, that is simple effective and a touch inspired and look much more stable than the other ways i have seen.

I will follow your thread with interest and i may even use some of your ideas (giving credit of course), "if thats ok of course"
