Nice video, thanks :)

When I'm grounding things I'm thinking about the full path that current needs to take to go to ground, and making sure there aren't any loops.

Thank you for your support. Yes, and the extra effort will certainly pay off with a stable robot. Thank you,

Hi Vince. Thankyou for your content and very wise words. I have a quick question am I right in saying that the connection from the input earth is jus connected to the Earth on the PSU in this video and as the PSU has a good grounding to the chassis the rest of the earths i.e. shielding is taken from the chassis to not create a loop. I wired up my CNC a few years back and the connection from the earth pin on the plug (which connects to the wall) has a good continuity to the CNC electronics enclosure and the earth into the enclosure goes directly to the PSU only. I still need to earth the shielding in a few cases but at the moment I suffer no stability issues. I junked the USB controller in favour of a CNCDrive AXBB ethernet and running with UCCNC which I like a lot and a step in the right direction. The USB controller did not like Windows 10 for starters, lol.

Thank you for your support. You're correct if your power supplies ground is properly grounding the power supplies enclosure then through conduction it will ground your CNC enclosure pending it doesn't have an insulating coating.
You would then just need to install a ground bus for the cable's shield drains, and you're all set.
USB isn't stable to be used with CNC robots unless they are using 100w-300w routers.
Thank you,
Vince

@@corvetteguy50 Thanks Vince 🙂 Having worked in IT for 20+ years I've learnt not to rely on USB for anything critical, lol. Plug and Pray as they say 🙂

Exactly! :) Thank you,

Question… I am running a 110v input 24v output power supply- are all the dc circuits (arduino, stepper drivers, voltage buck converters, pc fans) tied to their respective ground on the dc circuit, and all 110v accessories (power supply, chassis, line filter) tied to earth ground through the wall to ground rod? I am trying to prevent ground loops and want to make sure I have as much tied to common ground as possible. I have heard mixed input regarding combining a dc ground to 110v non-powered earth ground. Intuition says keep them separate. Let me know please! Thank you for all your insight into the trade

[@corvetteguy50]

Thank you for your support. Keep DC, and AC grounds separate in best practice. Thank you,
Vince

@@corvetteguy50 Awesome, I kinda figured as much. Thank you so much for your help

@@corvetteguy50 this question is important. I've watched this a couple times. If your vid is all about safety, I'd be concerned that multiple folks interpret the message as I did - telling folks to connect (AC) and (DC) grounds
