I am having some similar issues.
My X and Y are calibrated almost perfectly. However my Z hight is about 6% off. I can make a 25mm cube. The hight is 26.35mm. The X and Y are 25.00+/-.03. If my steps/mm where 80 insted of 100. I should see 31.25. I tightened belts and verified my that my steps/mm to be 100.
Anybody have an Idea where I should go next?. I am thinking my current setting may be wrong.
I am using RAMPs 1.4 with 16x micro microstepping.

(Current steps/mm / target height) x actual height = correct steps/mm
(100 / 25) x 26.35 = 105.4

Surely it's the other way round? He wants fewer steps, not more, so he needs to reduce his steps/mm to 25/26.35 x 100. But it still gives an odd number.

dc42,
I have measured the belts, and the pulley teeth. all as it should be, 100 steps/mm. I have read that MakerGeek may have given me the wrong motors. The current for these is around 400mA in steed of the suggested 1500mA.
The jerk and acceleration is a good Idea. However, I run the printer very slow because the extruder can't keep up.

I´m confused about the 17/16 teeth counts...
Do I count the teeth of the pulley or the dents? Because a 17 tooth pulley would have 16 dents, right?

Is it worth using smaller pulleys, like 12 or 10 teeth?
