Don't start with anything.? By this I mean dont buy a single thing NOTHING AT ALL. The most common mistake made is buying parts before final design is choosen and components decided upon.

Boyan How can you say the above with conviction. Windows is not crappy and you certainly do not require to change the hard drive to a flash drive. Hard drives will run for many years without any...

Dictionary wise both are same.

But in electrical engineering context both words differ in scope. Ground is a general term that refers to a reference potential against which all voltages are...

Grounding and Earthing often creates a lot of confusion and to some extent depends how old you are. But you don't connect your DC ground to the Star point which is the point where all the screens...

#1 3nm motor stepper motor will do everything you need for machien this size but that's not what will limit your DOC it's the spindle and the strength of the machine. Also Chip clearence is required...

Hi Ian

Many thanks on the comments and yes bang on with the supplier really helpful and good quality stuff.

As for the CAD software I have been tinkering with Fusion 360 it works on Microsoft...

In principle everybody is right, both CNC4YOU and I, and the UC300 manual...

The BoB you have can not be used to control the VFD with, unless you are ready to adjust the speed manually, or use a...

Hello nairepooc,

First off, let me apologies for not posting earlier. I have been very busy these past few weeks, but I finally found some time to take those pictures you asked for. I hope these...

Hi Iman,

Welcome to the forum. If you are just starting out then have a look here - it shows some of the finished machines built by forum members:

I've been thinking about that, and I'm not sure how to help further (apart from sitting together over a glass of something invigorating with the back of a big envelope and a pencil). The trouble is...

Just to be clear, opinions expressed below are not definitive or instructions to others, but are how I've built my own control cabinet.

Firstly, forget any idea that a fuse or MCB protects the...

Hello nairepooc,

Thank you so much for the compliment :) I do have pictures of the build but I won't be home until tomorrow evening, but once home I can post some pictures for you :)

All the...

One of the things I thought about was how best to fuse the 2 drivers which drive each side of the gantry.

I originally had one per driver, but in the end went for double the current rating and fed...

You could use a booster, however 12VDC versions of those relays should be available.
I only gave the 24VDC part numbers, as those are what I use, and had the numbers handy.

12V version of 3PDT is...

this is what we use.

There's nothing wrong with using a relay to switch mains voltage, provided it's rated for the voltage and current.
However going by the latest wiring diagram, you'll struggle to get a relay capable...

Why would you not put the VFD in a control cabinet?
Just because it creates heat and electrical noise is not a reason to not put it in a control cabinet.
Stepper drivers, servo drivers and power...

Neal they are separate grounds but you don't need 5 core 4 cores is enough. Heres how you wire it to IP-M controller.

Starting with On/OFF. Take DCM to Pin 25 then FWD to Pin 12 or 13 depending...

Plasma by it's nature is dirty business so no surprise when that fires up but drives them selfs shouldn't be messing with radio.

So many things could be in play here like you know but I'd...

No simple or easy answer to this because Noise and grounding is black art in it's self. Basicly what you trying to do is provide a path for any stray voltages to reach Ground and not feed back into...

Ok I've done you a quick Diagram but If your not going to listen your just wasting peoples time and I'm time short as it is.! So either take heed or don't waste my time asking questions your going to...

Apologies for resurrecting an old topic, but hopefully this extra info will help someone who isn't getting their head around running the proximity switches at a higher voltage and still being able to...
