General Mach Discussion / Re: Tool offsets in X and Y direction

« on: September 29, 2008, 03:06:46 PM »

Work offsets set up individual datums that can be used in many ways.

Lets say that your datum point for your torch is at X4.0 Y2.0 and Z-3. you would set these figures into G54 then in G55 you would put X5.0 Y4. Z-3.5 or what ever the centre distances were.

Then if you were using the torch the gcode would be started with G54 and if you are going to use the drill you would command G55.

You can change from one to the other at any point except with in a G52 local offset.

Your height offsets can be global or local to a particular work offsets.

You could call one G54 and the other G55

you could go into ports and pins and assign pins from Y into A in a different profile.

Have a look at this thread, its due to be released soon, there is a link in the LazyTurn thread to down load an taster version.

Hi Alex,

Lazycam has a limited amount of lathe tools, Lazyturn will be much better.

There are some rules to follow when importing profiles for turn in Lazycam, the profile has to be open and a single continuous line, it can not be a spline!

Make sure you output lines and arcs.  The picture is an example of a typical shape that will work fine.

General Mach Discussion / Re: Some questions about radius compensation

« on: September 21, 2008, 03:05:36 PM »

Hi Dave,

if you look at the code again I think you will see that KKamels code has no lead in to the diameter to be cut, to use G41 you have to move to the diameter to be cut to allow Mach to compensate.  If you check out my code that is what it is doing.

Regards

Graham.

This is the simplest way to do circles with comp. :-

G21 G40
T6 M6
G00 G90 X30. Y47.
Z1.
G01 Z-1. F50.
G41 X45.  F100.
G03 I-15.
G00 G40 X30.

G01 Z-2. F50.
G41 X45. F100.
G03 I-15.
G00 G40 X30. Z1.
M5
M30

What are you using to generate the g-code?

Yes it can be done, use a single point tool and lots of maths.

PM me your email address.
