G-Code, CAD, and CAM discussions / Load Mach3 with mastercam G code

« on: March 31, 2010, 09:27:57 PM »

Hi,
I started using Mastercam on 2D basis, everything goes fine, I then generate the G code there and do a copy paste  to a text document,  next I open Mach3 and load the G code from that text document.
The problem is, everything goes fine on the Mastercam simulation but on  Mach3,  with the same G code does not go at all or some other times goes very different from what I am expecting,  resulting in
a non usable piece of work.
If there is anyone who can give an hand on this, I would be much great full.
Thanks.

FAQs / Feed rate

« on: February 15, 2009, 07:51:08 PM »

Hi,
I am trying to get on with Mach 3 Mill, I am getting  there more or less OK, but some times there are things that I can not do as I would like to, for exemple the speed on the Z axis it is fine on G0, on G1 it is really very slow, I tried to alter the feed rate to a value I want but for some reason when I click enter the value goes to the default value again which is 6 and the movment with this value is very slow.
My questions are:

1-am I dooing the right steps to enter the feed rate value I want?
2-is the program not runing propperly, or did not set it up as I should?
3-shall I enter on the G code with the feed rate I need?
4-has it got to do with the steps selection I did for the motor?

If any one of you manage the time to give me a hand with this, would be great.
Thanks a lot.

FAQs / M98

« on: January 28, 2009, 05:03:07 PM »

Hi guys,
as this is my first time to program something to use Mach3 mill I decided to do something really easy, this is what I have programed:
O1000
G54 G94 G90 G21
M6 T1
G43 H01 G0 Z50
G0 X0 Y0
M98 P50 2000
G80
G0 Z10 M30

O2000
G81 R2 Z-12
G91 X5
G90 M99

What I notice is that Mach3 do not seem to accept M98, is there any one who could help me? Does Mach3 has a different code to call the sub-program?
Thank you very much for your help.
