Interference is a bugger to track down, but when you find it, it's all worth it, (but not when you find that you caused it in the first place, ask me how I know). Good job on finding it. I think I'd like it better if the controls were a bit closer to the front , rather than having to reach over to the back of the machine, but that's just me, I'm only short :), you made a nice job of it, I like it.

Thanks. It looks further on camera plus I was leaning out of the way to allow you to see the knee whilst I pressed the buttons. In practice it is fine for me to reach. Also saves me pressing it unintentionally and raising the knee into the workpiece.

I doubt that you are fighting a surge. More likely all those coils opening and closing are creating radiated EMI. This tends to get recieved by cables in the box. The cheap and easy way to deal with that is by adding a ferrite bead as close to the source of the high frequency noise. EMI is traditionally contained by using a "star" grounding methodology to protective earth. (not Ground 0v). Having shielded cabling with the shield running to a single PE will prevent wiring from capturing radiated noise.

Thanks. I think shielded cable would have been my next step on more of the cabling if the capacitor had not worked (the stepper motor cable was already shielded to PE via the lower panel, but other cables were not). I do have some ferrites so I'll try those if it starts playing up in the future. For now the capacitor seems to be working.

You must only be using a Class X capacitor across the main! Edit: sorry, when I saw the blue-and-brown cable...

Yes, poor choice of wires for debugging! Only 24VDC used here for the electromagnet, but good advice if I was using mains.

Love the toys r us hammer, a bit of a technical one for me love the 3D printing

Yes I have a storage case dedicated to wall fixings. Has brown, red, yellow plugs, 5, 6, 7mm masonary bits, small hammer (big one does not fit), AC voltage detector (to check for cables in the wall). So if I need to fix something to a wall it's all in there.

​@@routercnc9517I have something similar, everything ready in a compartmentalised box. However, I gave up using red plugs etc years ago. Now ONLY use various types of Fischer wall plugs. I know they can be 4 times the price, but I have never had the problems I used to get with those red and brown plugs. For the sake of a couple of pennies I know that I'm not going to be called back to a job because "Its come loose."

looks good 🙂

Thanks Pierre, good to see you still following along.

Do you have a flyback diode across the brake solenoid? Without it, you will be dealing with inductive flyback voltage that can cause noise the issues you are seeing. I also recommend that you isolate the brake solenoid circuit is isolated from the electronics, if possible.

I think I showed it in the video but yes there was a diode across the solenoid/electromagnet - it was at the power supply terminals. Yes the 24VDC circuit just goes from the power supply, through the relay contacts, and to the electromagnet, so separate in terms of the wiring at least. Looks like the capacitor sorted it anyway, thanks.

Choose the random seam position to lose that line in Bambustudio.

OK thanks, I guessed there was a way to sort that. I'll do that next time.

People that ask "but, why?" obviously have no clue.

Hi, I've just discovered your channel and I'll be here watching videos for a while xD Someone on garage journal linked me here, they thought you might have some advice for me on buying a milli n New Zealand (I'm in christchurch) ... would you be willing/have some advice to share? I have about 12k NZD to spend, should I be looking for a used VMC, a new Machinery House mill, a used second hand mill in that price range, or anything I haven't thought of? Thank you!

I don’t own a milling machine. I have built my own CNC router though. Current project is a heavily modified drill press but it cannot be used for milling. You would get a good response from the mycncuk forum. Lots more mill and VMC users. Thanks
