Hi Croy,

There are an awful lot of BoB's already available and here are just a few  http://www.cnc4pc.com/Store/osc/index.php?cPath=33&osCsid=879b109464028d53cd1fc711623e996a

But - there is always room for another so good fortune with your project and I look forward to seeing the pictures of your prototype etc.

Hi Sabastion,

Welcome to the forum.

I know the feeling - some mornings I wake up Grumpy, other mornings I let her have a lie-in.

General Mach Discussion / Re: Circuit board isolation routing and probing

« on: July 30, 2011, 01:41:25 AM »

Hi Sage,

I isolation route quite a lot of circuit boards, my work table has a (bolt on) sacrifical top which has been machined flat and parallel - the circuit boards are then held with double sided tape for machining and drilling.
The "extremely simple" boards are held on a vac table with the hole centres just spotted then the holes are drilled manually as a separate process.
The "complex" boards are still acid etched.

Sabastion,

Calm down - chill.

There are many here willing to help you in any way that they can.
There are also many thousands of extremely satisfied Mach3 users.
Mach3 serves me well but I accept that it may not suit everyone but if you are prepared to put in a little effort learning then I am sure you will not be disappointed.

General Mach Discussion / Re: Mach3 and Cutting a Circle

« on: July 27, 2011, 01:48:20 AM »

If you are cutting the circle with GCode created from a CAD program then there is a good chance that the circumference consists of many straight lines and depending on the resolution it could be quite rough and lead to the problem you describe.
Try cutting a circle using the Mach wizard which uses circular interpolation, which is as near to a curve as you are going to get, and see if that improves the situation.

General Mach Discussion / Re: Z axis help

« on: July 26, 2011, 08:18:50 AM »

Sorry Isaac and Sorry Gerry,

 I read the Manual and as I recall, it says that max Z is set to zero and everything else is a negative value but in practice this is not logical. The convention should, in my opinion, follow the way in which we use the machine with positive values as well as negative ones.

I can't help being weird - I was made that way.
