Usually I could follow that...maybe I have just been at this too long....
But what I have been doing is just this print a 10mm cube, measure then apply this formula
10/actual size * old step = New stepp
for instance my last print
10/9.7 * 182.59011 = 184.434455
My shafts are 5mm, my fishing line is .43 I am going to walk away for a minute so maybe my brain can process what you are telling me, then I'll look again after this print finishes.
On another note are you guys printing right on the glass or using blue painters tape, I cannot for the life of me get this pla to stick to the glass on its own. I did harvest it out of a scanner so maybe that has something to do with it.
And for what its worth, I have not noticed any knocking.

3.14159265359 * (5 + 0.43)=17.058848109
then for 1/16th steps and 1.8* per step -
200*16/17.058848109=187.585936609 esteps or rounded to 187.59 esteps per mm

Well would ya look at that I think I figured it out, this was a 2+ hour print and came out wonderfully. It really helps if your air conditioning isn't blowing across the print bed.
I have a whole other slew of problems with this print but I think its in the modeling more then the printers fault.
Was expecting a 2mm sidewall at the top, got 2.01mm; 3.87mm at the bottom, 3.9. z fell short at 43 of 44.5. The problem is my diameters are about 2 mm short on both ends.
Could it be shrinkage? Or is there something I need to know about printing circles?
Anyway THANK YOU ALL!!! Especially markstephen

The metric pitch on a 10-32 thread is .794 mm real close to .8 but over a distance can throw you off as your esteps works out to 4,030.22670025 / mm. Not so good trying to match an imperial thread to a metric based unit. There are not any standard imperial threads that will work out to even steps on a metric based system. Your best bet is to go for the metric thread and be done with it.

Awesome tips regpye, thanks. Those are some beautiful prints there, Hopefully one day I'll have mine dialed in enough to print parts for a mendel of some sorts. It's still giving me issues but I am almost certain its user error and slic3r settings more then anything. I am not using a m5 sadly they are hard to come by in my neck of the woods and didn't wan't to order another part but I am using 10/32 threaded rod and I am guessing the .8 comes from the pitch of the m5, I'll have to see if I can find the info on this rod I'm using until I can get ahold of some m5.
I have been pondering on the lights as well, I have a very hard time seeing the part in the shadows and some light would be a welcome addition.
At this point if I can just get the much needed "upgrades" done I will be 1 happy camper. My front Y plate has begun to sag from pressure from the weight of the glass and the heat generated by the stepper motors. I am also getting a wonderfull vibration at print but when I travel its almost silent, I cant seem to figure that out either but I am learning lots and have loads of fun playing in my scrap pile

Thanks once again Reg these tips are very useful. In regard to M5 rods i like to add that i noticed that INOX threaded rods are usually pretty good. And the galvanised ones are very bad, the thread is not as smooth as the INOX (it feels rough in your fingers) and a wobble is already visual as well (at least in my local hardware store..)
Impressive prints BTW

So much knowledge...thanks again guys I'll hunt down a M5 and shoot for INOX. Things are going ok now, If i can get my strings and circle problems under control I will be a happy camper for a while. Circles are consistently undersized and I have yet to understand why. Everything else in the model is x/y wise is spot on Z is off but we already know why I am having problems there. Thank you again to you all, this is definitley becoming my favorite new hobby
