Z-Axis will not move

[bmd]

Hello,

I own the Prusa i3 Acrylic kit: http://www.geeetech.com/acrylic-geeetec ... p-917.html

I am having trouble with the z axis. When using repetier, it does not rotate, it also doesn't work when I use the lcd. Homing the x and y work perfectly but not the z. It only buzzes. I tried adjusting the driver motor to a higher voltage but it doesn't help. Also, for my x and y, it appears that it doesn't move exactly 1mm (probably 3mm) every time I click, and when I press 10mm or more, it will only move a few mm.

Does anyone know of a solution? I can upload a video of my printer if it helps.

Thank you

Maybe you did not adjust the substep correctly. Please adjust it according to the tutorial

What do you mean by substep? Sorry I don't know that one.

You can refer to our wiki page: http://www.geeetech.com/wiki/index.php/Sanguinololu . You can find how to adjust step at chapter 4.

I do not understand the wiki. I dont see where it shows where I can adjust anything. Can I show you a picture of my board?

I don't see where it says I can adjust my step in chapter 4. Can I send you a picture of my board?

3 jumper caps should be plugged under each A4988 module. And there should be a jumper cap above the second A4988.

Oh I never received these in my kit. Where do I buy these caps?

[zhangxueyou]

That's impossible. They are packed with A4988 or other parts. Please check again carefully.
