Ok

200/ (52-3) x 100
or
200 / 49 x 100 = 408.16

where 200 is the original steps per and 49 is the output cut measurement minus the tool diameter, multiplied but the input cut measurement..


is that a Bit easier?

Its a brain doo'er i know

LOL

Just a tad - cheers :) I ended up with 409.62 using 3.175 as the tool diameter

Once we have got both axis to move the same amount i can do the math again and give you the imperial equiv, then we can change the system to old school as like swarfing said it could be a yank model. but we will get it for you then of course that will rule out the mechanical and software stuff as the source of your trouble, leaving only the electrics but they may be fine and just need proper BOB and stepper drivers should you be so inclined..
