and I've already calibrated the extruder (found that vid already, thank you though), its pulling in exactly what I'm telling it to.  But like i said, when i print the calibration cube its off a little, by .4 in some cases.

In the eeprom, x axis is set to 88 and the 5 mm calibration cube prints @ 5.42.  so 5.42 / 88 = 0.0615909090909091.  Than 5 / 0.0615909090909091 =  with some rounding is 81.18.  so x axis should be set to 81.18 .......  I think?    Maybe?  No idea........  Printing seems to be getting closer to 5 but I'm not sure what margin for error I should be expecting.

It's not perfect but I think that's pretty good.  the other weird thing, which is why I went to that guide, is the quarter is 24.37 mm in diameter, but i had to make it 25 mm for the quarter to fit in.  Also when I make the calibration cube, in the y  axis it's 5.4, the x axis is 5.2, but z is fine at 5 give or take .02 mm.

Know your stepper motors' full steps per revolution value. steps = 360 / angle, so 1.8° = 200 steps, 0.9° = 400 steps, etc.
(where do i find this?)

Know your stepper drivers' microsteps setting. Most Pololus are set to 16x. GEN3 driver 2.3 is fixed to 2 (half step). Some boards have 32x.
(........?)

Know the number of teeth on your pulleys. Standard printed pulleys have 8 teeth. Most machined pulleys have 10 or 12 teeth since 8 tooth is technically too small for T5 belt
(where do i find this?)

Know your belt pitch! XL and T5 belts /look/ the same, but the difference is important!
(what is this?)

Know the number of teeth on your extruder gears, or at least the gear ratio.
(where do i find this?)

Remove all sources of backlash. Your parts won't be usable as calibration pieces if you have lash!
(what is this?)

Open the Online RepRap Calculator to find XY and E steps, layer heights, and acceleration.
(help)

The issues i've been having are my circles are really bad, if i make a print that 25 mm circle, it makes one thats 23, and it seems my y axis is slightly off.  Ive been printing the calibration cube and front to back the infill is off ever so slightly.  Like i said doing my best to search out definitions but im kinda at a loss on this one.
