General Mach Discussion / cad/cam for a newbie wizard liscence??

« on: July 27, 2012, 10:39:30 AM »

A search of the forum dug up a topic which contained the remark below.

"For starters you may consider just using the wizards in Mach3 mill. Better yet, pay the $50 for the Newfangled Solutions wizards license and you will be able to do most machining jobs without the need for CAD/CAM software at all. This conversational programing is a good way to go I think."

excuse my ignorance - but what is this all about?  the wizards liscence bit and what is conversational programming?

General Mach Discussion / Gcode -using a period in parameters

« on: June 25, 2012, 11:21:25 AM »

Hello There all of you

I am writing a program which will output gcode for simple machining

If I am using a parameter as say for instance
#11=30.5    ( where 30.5 is a dimension for roughing out)

Is it allowable to use a period within the paramater for instance
#11.1= 30.0 ( where 30.0 is the finished size)

many thanks

General Mach Discussion / viacad and cambam

« on: June 22, 2012, 04:06:50 PM »

Hi everyone,
"Model engineering workshop" magazine is running a very interesting and easy to follow
tutorial entitled "bridging the cad cam divide.
the programs they are using are Viacad and Cambam.
I would appreciate input as to the suitability of these two for use with mach3
-primarilly for lathe and later for milling?

I have used autocad 2d extensively so am moderately cad profiecient


any comments,suggestions,thumbs up or thumbs down??

many thanks

General Mach Discussion / calling subroutines - (corrected post)

« on: May 30, 2012, 11:04:22 AM »

Sorry chaps- something went wrong with the previous post and it posted before i had finished
typing

Here is the correct post

   

Hi guys.
Mach3 on a lathe
My question is can a subroutine which contains parameters be called more than once but with different parameters

An example would be like tis
-------------
------------
#1=10        ( parm 1=10)
m98 p2 l3    ( calls 02 with value of #1=10)
----
---
more code   

#1=20        ( parm 1 now reinitialized to a value of 20)
m98 p2 l3    ( same sub called again but with different value of parameter)
--------------
--------------

m30
( ----eop:test prg--------)

02                    ( subrourine 02)
g0 x#1 z5         (doing something with the parm #1)
da-de-da-de-da

M99    ( return to main)

General Mach Discussion / using variables

« on: May 19, 2012, 07:37:39 AM »

Hello all -- the  copy and paste below is  from an earlier topic on using variables

My question is whether use of vars is restricted to these numbers or can alpha characters be used?

regards

fred



You do it like this

To set a variable :-

#1=3 (use numbers #1 to #100  or #500 to #600)
#2=50
#3=[#1+#2]
#4=[0-10.5] (to set minus numbers)

To use that variable :-

G01 X[#4]
G02 X[#2] Y[#3] K[#1] F10. (etc.)

General Mach Discussion / canned cycles vs. subroutines

« on: May 19, 2012, 06:38:04 AM »

Please help

Canned cycles ( such as g ********* ) versus subroutines ( m98 and m00)

When does one use one or the other.

many thanks

General Mach Discussion / synchronize config on 2 computers

« on: May 18, 2012, 01:44:07 AM »

Morning chaps--
( well at least it is morning here!)

I have a computer in the workshop and my laptop in my office
I write code and drawings on the laptop  and machine in the workshop.
Both have mach3 installed and I want to ensure that they have the same configuration.

Which files and folders must be synchronized?

Many thanks

General Mach Discussion / easy motor tuning

« on: May 11, 2012, 04:29:26 AM »

Hello Chaps-  Please tell me is this is an acceptable way to correct a stepper motor
 that is not measuring correctly

Select this page

Config->motor tuning
 Example setting Z axis on lathe machine in millimetres
after setting the zero position on the Axix dro to Zero and pressing enter
I give the instruction G0 Z-100

Then I measure the distance actually moved and find that it has moved 110 mm

My current setting in steps per is 250

I do the followimg sum   250 divide 110  multiply 100  = 227.27
enter 227.27  into the steps per-- window in motor tuning screen
regards
