Hello everyone, I assembled my reprap from parts that i bought 5 months ago. It worked well in the first 4 month. My reprap's Z axis is actuated by 2 stepper motor LDO-42STH47-1684A as shown in attached file. The problem is now the right one sometime rotates in the opposite direction with the left one or not rotate at all. Especially, when i were trying to do the Z offset. I tried to re-wire the motor, actually, i re-wired all the electronics parts but the result is still the same. Is it because of the motor or the wiring or the coding in Arduino processor? I have tried to fix this problem for nearly a month. Please help me. I am so depressed right now. https://reprap.org/forum/read.php?160,601534,601534#msg-601534 Tue, 19 May 2026 14:14:41 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?160,601534,601960#msg-601960 https://reprap.org/forum/read.php?160,601534,601960#msg-601960
I triple checked the wires and it fell out as your suggestion.
