So I built Rostock Mini and I got it together, but now there is one problem that I simply don't understand how to fix. When I press the home button on Repetier Host, the printer moves only little bit up, and the z axis + and - does not work otherwise than only up. It seems that I cant get the platform come down at all only up. I tried inverting endstops in the code but nope, I've tried setting the home position on Repetier Host to either Min or Max but nope, I've tried to flip motor connectors but nope. So when I give any command to the printer it always keeps going up even when it hits the endstops. https://reprap.org/forum/read.php?4,399481,399481#msg-399481 Tue, 13 Oct 2026 06:45:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,399481,400214#msg-400214 https://reprap.org/forum/read.php?4,399481,400214#msg-400214 rwindr Reprappers Thu, 28 Aug 2014 10:08:22 -0400 https://reprap.org/forum/read.php?4,399481,399951#msg-399951 https://reprap.org/forum/read.php?4,399481,399951#msg-399951

Go through the steps on [minow.blogspot.com] Or [reprapandme.blogspot.com]

You'll have to adjust the corridinates to your bedsize (if it is smaller), but once you have it printing flat you'll be off to the races.

Now next thing is to calibrate this thing. First test cube had one side fall off in mid print. :)]]> rwindr Reprappers Wed, 27 Aug 2014 14:08:05 -0400 https://reprap.org/forum/read.php?4,399481,399883#msg-399883 https://reprap.org/forum/read.php?4,399481,399883#msg-399883
It also appears that the motors are moving in the wrong direction. Invert their direction.

I'm more familiar with marlin firmware, but I will have a more thorough look at it later.

But the problem seems similar to the one experienced in this vid: [youtu.be]

(Speed up to where he has the printer working).

The problem was his endstops needed to be inverted.]]> Wildcard Reprappers Wed, 27 Aug 2014 13:28:28 -0400 https://reprap.org/forum/read.php?4,399481,399853#msg-399853 https://reprap.org/forum/read.php?4,399481,399853#msg-399853 pastebin.com]
And here's my repetier host printer config: [imgur.com]

A vid could help also.


If it makes a weird nose and shutters during the movement. Change the homing feedrate from 200 to 100.]]> Wildcard Reprappers Wed, 27 Aug 2014 12:06:11 -0400 https://reprap.org/forum/read.php?4,399481,399842#msg-399842 https://reprap.org/forum/read.php?4,399481,399842#msg-399842 rwindr Reprappers Wed, 27 Aug 2014 11:51:52 -0400 https://reprap.org/forum/read.php?4,399481,399836#msg-399836 https://reprap.org/forum/read.php?4,399481,399836#msg-399836 Wildcard Reprappers Wed, 27 Aug 2014 11:37:15 -0400 https://reprap.org/forum/read.php?4,399481,399793#msg-399793 https://reprap.org/forum/read.php?4,399481,399793#msg-399793
