AndyUK's Build - 1.2x1.0m Gantry

[MikeyC38]

Hi Andy. Didn't see an answer to your question about VFD harmonics. I fitted an emi filter from the mains to the input of my control box using one of these https://www.ebay.co.uk/itm/EMI-RFI-F...edirect=mobile . This plus star farthing all the shielded cabling eliminates the problem I had when the vfd was running (false estops). Also mounted my vfd external to the controller again to avoid electrical noise getting through.

Hi MikeyC,

Thanks for the tips! I bought three of those from Ali Express a while back; I chose three because I placed them after the mains input and before each main component (VFD, 24V PSU, and Drive PSU) - hopefully so that noise from each didn't affect the other, because it had two filters to pass through, if that makes any sense. When it came to wiring them though, I realised the IEC cable wasn't what I wanted (being that theres three inside the cabinet), so I got some alternatives with spade connectors on. Something like this.

Thanks for that link!

By the way do yiu have a youtube chabbel? I saw a very similar if not the exact same build. Joe Harris is the name of the channel.

Yep - If you look at the start of this thread, you'll see its heavily based on Joe's build. I'm a bit more camera-shy though, so haven't gotten on the old youtube.

In other news, I'm slowly but surely wiring away. Taking a little time over it - life has become rather busy at the moment with all the other distractions :) I'll try and post a picture of current progress sometime this week.

Thanks,
Andy
