Hello, I'm working on my first reprap, and just finished soldering my sanguinololu 1.3a. I was about to start wiring stepper motors when i noticed that the z axis has a spot for 2 4-pin headers, although I can only fit one. I was wondering if it is acceptable to put the 2 z axis motors in series instead of parallel like the board has them. I've worked with other repraps and we just connected 2 of the compliment wires to each other and had 4 wires going into the board for the z axis. oh and one more quick question, my steppers have 6 wires. I'm guessing I just dont use the black and white ones but just wanted to make sure here first. Thanks in advance! https://reprap.org/forum/read.php?158,107279,107279#msg-107279 Sat, 10 Oct 2026 17:08:35 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?158,107279,107304#msg-107304 https://reprap.org/forum/read.php?158,107279,107304#msg-107304 ElMatador Sanguino(lolu) Tue, 22 Nov 2011 14:13:38 -0500 https://reprap.org/forum/read.php?158,107279,107300#msg-107300 https://reprap.org/forum/read.php?158,107279,107300#msg-107300
You could use half the coils and put them in series. That would give the same torque for a given total current because you then have twice the current and half the number of turns in each motor. The inductance would be less so the top speed would be greater.]]> nophead Sanguino(lolu) Tue, 22 Nov 2011 13:27:37 -0500 https://reprap.org/forum/read.php?158,107279,107291#msg-107291 https://reprap.org/forum/read.php?158,107279,107291#msg-107291 ElMatador Sanguino(lolu) Tue, 22 Nov 2011 12:21:54 -0500 https://reprap.org/forum/read.php?158,107279,107287#msg-107287 https://reprap.org/forum/read.php?158,107279,107287#msg-107287 these.]]> ElMatador Sanguino(lolu) Tue, 22 Nov 2011 11:39:24 -0500 https://reprap.org/forum/read.php?158,107279,107279#msg-107279 https://reprap.org/forum/read.php?158,107279,107279#msg-107279 I'm working on my first reprap, and just finished soldering my sanguinololu 1.3a.
