Hi Tweakie

Thanks for the info. yes my idea was and is to learn only what I need - so I thought narrowing down the info will make me learn what I need and not waste too much time on what I don't.

I guess you are saying the same but from the other end - cheaper though  ;-)

Cheers

General Mach Discussion / New to CNC, seeking sources

« on: July 25, 2011, 09:04:04 PM »

Hello all

Since I am VERY new into CNC    - and was surfing quite a bit to get information - It seems there is so much info I have no idea where to start from.

Since I will be using a small router with Mach3 - can you guys recommend a good book, manual or e-book that explains CNC programing with the system matched best for Mach3 ?  (there are CNC numbers starting with "8" - have no idea what they are and which one is suitable for Mach3)


Any help will be very much appreciated.

General Mach Discussion / Re: Z axis help

« on: July 25, 2011, 08:21:39 PM »

Hi Guys

Thanks heaps for your kind support.

So as I understand it - the machine coordinates can be set for 0.00 at the most top of the Z axis and the negative number will represent the full stroke of the Z axis. When zeroing for the part coordinates - it can get a positive number since it is still in the soft limits area.

The troubles I had with the other program was probably due to the fact he put an absolute code in - hence there cannot be any positve number at all


So much to learn - but I love it.

BTW - I am more then happy to pay the price...    

Cheers

General Mach Discussion / Z axis help

« on: July 24, 2011, 10:32:08 PM »

Hello all

This is my first post - so you know I am a real noob :-)

I am confused with the Z axis zeroing and direction of movement:   (I will use this with a router)

In Mach 3 video - it was recommended to set the max value to zero and the min value to the actual travel of the z axis. The example was   -200. So I understand the logic is to home the z axis to the top as a safety issue. So when cutting a job - I will jog the z axis down to the work piece and zero it - then to cut the material my logic says to put negative numbers. (say -0.1)

However on the sample programs, I see some positive numbers and when trying to execcute -  I get the soft limit warning.

In the Multi pass wizard - (which I will surely use) all the numbers are positive again, and the video says to put for example 0.75 as a negative value

Can someone please help me understand this issue ?

Cheers

Hello

My name is Isaac Neuman, I live in New Zealand and my main hobby is building flight simulators. After paying heaps of money to some guys with CNC machines, I thought it's time to get myself into this area learn and do things myself.

I am curently building a small cnc router with HobbyCNC board and Mach3.

As a noob I would probaby need lots of help and I know some guys here will be a great help.

Looking forward to learn experience and aquire some new skills

Cheers


Isaac
