Here's the real money shot. This right here is why all the mods and continued building. This is what makes my printers better than the rest(potentially). Check out all the steps I get per mm of travel on each axis. And even the extruder..



320 steps per mm on x and y is outstanding. And it is achieved with a combination of 0.9 degree stepper motors and drv8825 drivers. The rest of you get to have only 160 or 80 steps per mm of travel. 1/2 or 1/4 the resolution. I only bothered with these steppers on x and y. The fine thread lead screws put the z axis into a really high step count and the geared extruders do the same. The titan I am using here is 3:1 gear reduction. which translates to 3 times the amount of steps per mm of filament travel or 3 times finer control.
