Electronics for New Machine + Chinese Spindle + VFD

UCCNC seems to be fine.

I cannot get it to crash or stop and I have just run several jobs successfully. I even ventured up to 2500 mm / sec feed rate towards the end and no problems.

Weird why that should solve it.

I have to say I like UCCNC a lot. It's cleaner and has a much better interface, and is much simpler which is what i have been after. So i will keep an eye on it for now until i have some confidence it's not going to go mental on me.

Cheers Chaps. Thanks for all your help.

Not so wierd if you have a suspicous mind. Doesn't take genius to see the advantage of the plug-in not working so well with Mach3.!!!

Hiya,

I hadn't seen this reply before I posted mine, fingers crossed for you and good luck.

To add to my reply, I did wonder if it was a problem with the controller but I wasn't sure if you had hardware from them or not.

Ok. So after some more testing with the UC CNC software i am still getting the odd reset during a cut. No crazy lost steps though which is good.
So I have decided I am going to bite the bullet and redesign a new bigger box for all the electronics, as I am sure the packed in proximity of everything is part of my problem.
At least now I can use the machine as is to make it.

I am planning to make the box out of 18mm birch ply as i have it.
I would ideally like to get the vfd in the same box, but with a significant internal shield to separate it from the sensitive stuff.
Also I am wondering whether my dust extractor which sits under my bench in fairly close proximity to the box could be causing me a noise problem as well.

Can anyone tell me what materials block noise? Or would you fail safe and just separate the VFD completely.
Would it also be sensible to separate and shield the mains stuff from the low voltage stuff ?
I assume wood doesn't do anything.

M,

you are in Bristol right? Would you like me to come and have a look? 4 eyes better that 2.

[mturneruk]

If you think you might be able to advise me on how to improve my set-up that would be great.
Where about's are you?

Thanks
Martin

Conductive and earthed ones, that's why metal boxes are the norm. Ferro magnetic ones are best.

I ordered 3 rolls of copper shielding adhesive tape today.
My plan is to stick that all over the inside of my wooden box.

And possibly have metal shielding between the various internal sections as well.
Hopefully that will do the job.

Following a very kind visit from Komatias, he suggested that I may have a ground loop.
So before I go off building a new box I am going to to try his suggestions, and see if I can't get rid of my Gremlins that way.

However the machine is now working well enough to make these. My fist commission!



Thanks to all of you lovely people who helped me to get my machine going!

Dod you have a chance to sort your groundloop out?
