Evening all, setvup the cnc tonight on half steps and all was going fine just a bit noisey, so decided to try 1/16th step but when i do this when i tell it to move 5mm it moves 30?

Now i got 200step motors at 16th so thats 3200 steps per rev?

5mm direct drive lead screw

3200/500= 640steps per mm which is what i have entered into motor tuning.

Is my maths correct or have i gone totaly off course? Cheers simon
