Hi, I have put together my Prusa, and I tried to play with it. When I connect only one Z motor to control board, everything works fine, but when I connect both Z motors, it won't move. What's wrong? I have connected just like shown here: [reprap.org] Do you think that maybe two springs used to connect X axis to Z axis are to to stiff and when it comes to one motor it is ok, but when it comes to two then force to overcome to move it is too big? https://reprap.org/forum/read.php?151,127423,127423#msg-127423 Wed, 17 Jun 2026 02:13:27 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,127423,127427#msg-127427 https://reprap.org/forum/read.php?151,127423,127427#msg-127427 nophead General Mendel Topics Thu, 05 Apr 2012 04:01:34 -0400 https://reprap.org/forum/read.php?151,127423,127423#msg-127423 https://reprap.org/forum/read.php?151,127423,127423#msg-127423
