| Jan 30, 2018 at 23:06 | comment | added | Jack Creasey | If you are using the L293D ...then you don't need external clamp diodes ....they are built-in. A 12 V stepper motor has very high resistance windings ...are you sure your a high voltage version?? Do you have a datasheet for your stepper? | |

| Jan 30, 2018 at 22:23 | comment | added | D.A.S. | You better get diodes | |
| Jan 30, 2018 at 22:21 | comment | added | Fraser | No clamp diodes but 2 motors were connnected | |
| Jan 30, 2018 at 22:20 | comment | added | D.A.S. | Did you connect clamp diodes and motor? | |
| Jan 30, 2018 at 22:18 | comment | added | Fraser | No, I've only connected pin 4 to ground as this works with other motor circuits I've tried and tested. In my past experience, not all GND pins need to be connected to ground. | |
| Jan 30, 2018 at 22:16 | comment | added | D.A.S. | Are 4 Gnd inputs 4,5, 13,12 connected? | |
| Jan 30, 2018 at 22:14 | comment | added | whitegreg56 | Do you have pins 5,12,13 connected to ground and a heatsink as the datasheet says?? | |
