Thank you for demonstrating and for your passion on the topic
Thank you for your support, and kind words. Vince
thank you so fucking much, especially the flux part and the "no matter which cable connects to either u, v or w". you changed the way i'll solder for ever !
Thank you for your support. I really appreciate it! Vince
Thanks for the info. However, I don't quite understand the last point about using shielded cable for the VFD input as well. From my understanding, we would use double shielded cable for VFD -> spindle to mitigate the high frequency noise caused by the VFD switching transistors (let's say 10 KHz). But why use it for the 50/60 Hz input? I don't think I've ever seen household appliances use shielded cable.
Thank you for your support, and your question. Double shielded cable is in best practice to be used as it mitigates the spread of EMI around your robot/controller in both frequencies.
You're correct home appliances don't use shielded cable, but they also aren't vulnerable to stability from the EMI they produce. They only have to worry about turning on to function.
Robots are a completely different animal from a regular power tool, or appliance and require an environment of low EMI to produce a stable system.
Robots unlike other systems can appear to be functioning correctly, but may lack consistent operation. If an end user for instance uses the proper cable for their spindle, and not their switches can produce a lack of consistent operation called "ghosting" .
The correct double shielded cable will provide the end user piece of mind, and a stable robot.
@@corvetteguy50 Thanks for the detailed answer. It is helpful, since I'm building my first CNC machine (PrintNC mini)! I also plan to use an EMI filter on the VFD input and a ferrite ring on the VFD output to further mitigate electrical noise.
If you use double shielded cable an EMI filter, and ferrite rings aren't required, but I certainly love the attention to detail :) Thank you,
Vince
I always assumed most solder was "flux core" and one didn't need separate flux with that. Is that reasonably true? Regardless, I'll be more careful going forward, thank you for the video.
Thank you for your support. The flux inside the solder is simply to help the solder clean the surface its about to be applied to. Its in no way a substitution for using the proper flux to allow proper wetting, and for the solder to begin capillary action. Its a must, and i assure you once you use it you'll love your finished joints when they're completed properly.
Thank you,
Vince
No flux no soldering . Quality soldering always need flux,shoddy soldering does no need flux
Thank you for your support. I couldn't agree more..:) Vince
As I understand it, shielding is to prevent EMF (EMI) interference. How do you personally measure EMF? EMF just seems like the infamous boogey man, and a way to measure it should help determine if it is a problem. Thank you.
You would utilize an EMF meter, but the issue is just how much EMF effects your robots signals. Each environment is different, so the results will vary which is why it's such a "boogey man" as you said.
Thank you both for your support. The Storyist is correct. EMF can be measured, but it's the amount that each individual robot's breaking point for signal stability that counts. Its simply has to many variables to get accurate data for each that provides definitive consistency.
@@corvetteguy50 Fair enough, but being an engineer numbers are how I know I actually achieved the change I wanted. Something along the lines of, I changed this and got a 25% reduction in the field. After 44 years in the field, you can see this approach is causing my internal gears to grind and bind.
