Well firstly before answering this you need to understand exactly what Mach3 or UCCNC or any machine controller for that matter does exactly.? It's common for new users to believe they do more than...

That brings you on to the next area you'll need to learn about, speeds and feeds.
Every cutter will have recommended ranges for feed per tooth, and surface cutting speed.

From those figures, you...

Not at all mate, the thing is with electronics, is if you just guess and turn it all on you quickly realise that all you have to show for your work is a bit of smoke and a new shopping list of parts...

If I may just put a comment in here about your soldered joints. I speak from the position of running an electronics manufacturing company for 30 years.

The pads on the PCB are not ideal. Large...

Why thanks bro, from the Frankenstein beginnings to my little neat one, it's been loads of fun.
When you see my sheet cutter you'll see the neatness hasn't made it that far.

I had a quick browse...

The other thing to watch out for when soldering boards like this is the tiny whisker of solder that bridges two connections. Can be difficult to see. Can't tell from the photo, but a scratch between...

yeah those are your drivers, what you referred to in an earlier post as your new driver board is actually your motion control board.

Again, only working from educated guesses given the blurry pics...

G'Day Ravi, as one layman to another, I know it can be tricky getting succinct info on this subject.
Here are a number of references that I have kept on this subject, that I hope may be of some...

Ravi, like this:



Basically you are building a path for any electrical noise that may target your cable and give problems, so it can leave the system.

the screen is just metal that picks up the noise and passes this noise back to ground as current, so as long as you have a good connection to ground that is all you need. so use your initiative and...

Ravi I would re solder (re flow all the motor connections that look and are bad on that board) as they will give you trouble and it si possible that could blow the drives if there is a dry joint....

Enjoying your thread Ravi, thanks.

Well post some good pics up when you can.

Typically you will have at least one switch per axis that is used for homing. That is, when you first fire up the machine at the start of every session, you "home" all axes. The software moves the...

I switched from Eding cnc to Mach 3 last year and Im pretty much regretting it. If only cslabs would do a plugin for UCCNC!!!

I am a simple soul and have easily set up Planet CNC. With a bit of help from Zapp and Planet CNC support.
pm me if you would like to discuss.

The limit switches are micro switches with an attached lever.

They are available from RadioShack and the like; the ones shown here are from Mouser.com (part number 101-1203).

They are single...
