No idea, it came with a 220v PSU not that that means diddly squat - so if I tear it down to the point I can reach the screws how do you do measurements, the same as measuring the pitch on a normal screw?

I get 1500.68 methinks I did summut wrong

3. Carl measure the pitch of the leadscrews

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

why not just follow 1 path at a time then the chap wont get too confused..

6. Agreed......

Just turned it over and measured the Y and I get 3 to a cm - whatever that works out to *shrug*

3 turns to a cm yes? What ever they are i suspect the pitch is not the same for x and y

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

Yep 3 to a cm the biggest problem with trying to measure the X is it is fully enclosed and I'd pretty much have to tear it apart to get to it but I shall attempt to get a close as damn first :)
