| Oct 22, 2020 at 12:18 | comment | added | Overrice | I don't know if someone else posted this, but, you don't need a 5v actually grounded supply; you just need a common ground. Connect the ground of the 24V source to the GND pin of the arduino, then you should be able to plug it in without any issue. | |

| Sep 20, 2018 at 3:48 | comment | added | Mtl Dev | Just wished to express thanks, your pointers (and not closing this question) enabled me to both learn more about this field, and actually find a final solution! Also found Fritzing, in order to be able to provide better diagrams, as wisely advised, Eagle next. Thankyou for your time! | |

| Sep 19, 2018 at 22:08 | comment | added | Mtl Dev | Appreciate all the advice, and what is a suitable format here. FYI I'm getting closer, following your advice of researching ground differences. The USB-derived logic supply comes from an "Intel NUC" desktop, which is DC powered only - no ground - so I presume this to be "floating" in reference to the 24V power supply, which I confirm is earthed. I will obtain an earthed 5v power supply, connect to same earth as the 24v supply, connect both 24v & 5v grounds, then power arduino, and test that...(and make a higher quality diagram and post, for the next guy or gal) | |

| Sep 19, 2018 at 15:44 | comment | added | Mtl Dev | Thankyou Sam, I understand. I will not give up, I will keep trying until I figure this out, I will post an answer if/when I do. FYI I am not convinced the 24v-only test is valid either, I made a separate question to ask that and only that question. It seems strange to me that I am seeing 24v on the 5v rail - and for sure the arduino was seeing 24v too. FWIW, the board schematics are here | |
| Sep 19, 2018 at 15:18 | comment | added | SamGibson♦ | @MtlDev - Thanks for trying. After more research, I now have so many questions that I've run out of space and time to write them. I'm not convinced that your new 24V-only test is valid (and may be an XY-problem). It's not clear exactly which SilentStepStick you have (there are several different ones) for me to find the correct schematic. And your new test doesn't address the previous worry of ground differences between the 24V supply and the logic (USB-derived) supply. So in your shoes, I would be doing different tests, but this Q&A site isn't suited to long troubleshooting threads. Sorry. | |

| Sep 19, 2018 at 2:54 | comment | added | Mtl Dev | Thanks, I'll make an image of the following: Only two wires connected: the 24v power supply, to "VM" and GND. In this state, if I put a multimeter across VM and Vio, there is a 24 volt drop between the two pins. I am trying to understand if this is a problem, or correct behaviour. (with my limited understanding, it appears this is the path that the 24v is taking to get to the arduino). Arduino power supply is from a DC-powered desktop, an Intel Nuc. | |
| Sep 19, 2018 at 2:25 | comment | added | SamGibson♦ | @MtlDev - (a) FYI, for me (and perhaps others too), the lack of an overview diagram showing all of the interconnections (especially power-related wiring) and the lack of photos (sometimes readers spot things which aren't obvious to mention in the question) are problems. Without them as a start (further additional info might be needed later) it's too difficult to be sure that I'm accurately building the correct mental picture based on the words alone :-( Please can you consider adding that info? (b) What is the Arduino power source? USB from a PC (laptop? desktop?) or wall wart? Thanks. | |

| Sep 16, 2018 at 23:57 | comment | added | Mtl Dev | Right now, just touching the outer part (shielding) of the USB-B plug from my computer, to the outer part (shielding) of the female USB socket on the arduino - there are clearly visible sparks. Checked with multimeter - 24volts is there.(!) Removed all wires from Arduino - except 5v lines, still have 24v. So 24v is coming into the Arduino from the GND and Vio pins on the driver. How is this possible? What to do? | |
| Sep 16, 2018 at 23:37 | comment | added | Mtl Dev | Question: I am in a older building, I don't trust the mains wiring in the house, but the wiring in my room is good. It's not impossible there is no earth to my room, will have to check. If neither the 24v power supply or my computer are actually earthed (but connected their earth wires are connected to earth other) could that cause this problem? | |
| Sep 16, 2018 at 23:35 | comment | added | Mtl Dev | Thanks. I have 0.7Ω resistance on the wire from GND on the stepper to GND on the 24v power supply - could that be an issue? The 5v source is via USB from my computer. | |
| Sep 16, 2018 at 23:03 | comment | added | Tom Carpenter | Hmm. I'm wondering if there is an earth problem somewhere - getting sparks when you plug the USB cable in suggests that the power supply ground (and hence circuit ground) is leaking current from the mains, hence you get a spark when you plug in to your computer. | |
| Sep 16, 2018 at 22:53 | comment | added | Mtl Dev | A decent one, 41.7amps | |
| Sep 16, 2018 at 21:27 | comment | added | Tom Carpenter | What 24V power supply are you using? Is it a decent supply, or a cheap wallwart? | |
