| Aug 5, 2020 at 13:06 | comment | added | user248702 | I suppose so, one thing I did change was that the reset and sleep were connected together. This shouldnt be an issue though. | |
| Aug 5, 2020 at 13:00 | comment | added | Emre Anıl TERZİOĞLU | I am not sure but maybe you need pull up for RESET pin. But interesting thing is, it was working with connectors with the same code and the same connections so it must be a soldering issue if nothing else was changed. | |

| Aug 5, 2020 at 12:53 | comment | added | Emre Anıl TERZİOĞLU | @Niall895 what is happening if you disconnect Arduino Pin9 and STEP pin connection. Is motor act the same? or stop buzzing. | |
