I have 2 Stepper Motor Driver v1.1 boards (x and y) and 1 Stepper Motor Driver v1.2 board (z axis) connecting to an Ardunio breakout board. I have two minor wiring issues: 1) Where do I connect the Enable wire from the driver boards on the Ardunio breakout board? 2) The version 1.1 boards have sync wires that are to be connected together but the 1.2 board doesn't, what am I supposed to do in this situation? I've connected the 1.2 board as Z as I assume the sync wires are really needed when the motors are running together which the x and y can do but you can live without for the z axis. https://reprap.org/forum/read.php?13,21402,21402#msg-21402 Tue, 14 Apr 2026 16:57:41 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,21402,21534#msg-21534 https://reprap.org/forum/read.php?13,21402,21534#msg-21534
For example if you used 4 steppers for the Z axis.

using the syncronize wire you could save on buying some components.

If your stepper controllers are well spaced from each other.

I would worry about the Sync signal getting interference,

I don't use the common sync.]]> BodgeIt Controllers Tue, 17 Feb 2009 13:21:35 -0500 https://reprap.org/forum/read.php?13,21402,21532#msg-21532 https://reprap.org/forum/read.php?13,21402,21532#msg-21532 is there any performance loss by not connecting them?]]> ralphthompson Controllers Tue, 17 Feb 2009 12:56:38 -0500 https://reprap.org/forum/read.php?13,21402,21408#msg-21408 https://reprap.org/forum/read.php?13,21402,21408#msg-21408 mccoyn Controllers Thu, 12 Feb 2009 20:04:21 -0500 https://reprap.org/forum/read.php?13,21402,21403#msg-21403 https://reprap.org/forum/read.php?13,21402,21403#msg-21403 reece.arnott Controllers Thu, 12 Feb 2009 17:33:46 -0500 https://reprap.org/forum/read.php?13,21402,21402#msg-21402 https://reprap.org/forum/read.php?13,21402,21402#msg-21402
