Sorry if this is something simple, first time dabbling in 3d printing, and I have been learning a ton throughout the build. the build is complete, everything seems to be functioning as intended. The issue I've come across is the Z axis, when I go to manually move it, does not move as far as it thinks it is. to help clarify what I mean. say i turn the bigbox on with the z all the way down, and manually try to move it up, it will slowly move upward, but it stops when the display shows 300mm, but in all actuality, it has only moved less than halfway up, maybe 140 or so mm. I have to turn it off, and back on, then repeat until I can move it up all the way or down all the way. I used the 1.8 degree motors, the z axis steppers are set to .569 volts. am I missing something here? would adjusting the z pot to .6-.65 help at all since they are tied together on the board output? I'm just not sure what kind of issue I'm having at this point, any help would be appreciated!
