Hi,

I just received and installed the Mach3 software I got from a dealer in New York. My name appears in the license window. It appears everything is working normally.

Can I install the software on my computer in my office also? Sometimes I want to write the G Code in the office then transfer it to my computer in the shop.

Thanks,

Billy

Thanks Gerry,

This program worked. I think this was the reason I came up with two overlapping circles when I tried to program this.

I would have needed to read the 40 pound book for a month to figure out the G91.1 business...lol

Thanks again,

Billy

This is what was produced when I loaded the gcode. Perhaps I have something set up wrong in the program.

Thanks Rich,

I will give the book a try. Also thanks for the G55 idea. On several occasions, I needed to cut a series of circles in various places on an electronics chassis. I got it done by manually moving things around. Not the best approach....lol

It has become obvious to me that some form of training is needed. I hope Peter's book will do well for me.

Hi,

I am trying to learn G Code. I want to cut two circles side by side on the X axis.

Here is simple code without lowering the Z axis. I am not having any issue cutting single circles.

%
(1 inch circle)
G01 G20 G40 G49 G90 X0 Y0 Z0 F2 (SLOW FEED RATE BECAUSE I AM JUST LEARNING...LOL)
G02 X0 Y0 I-.5 J0
G01 G90 X0 Y0 Z0 F2
M30
%

How do I get the machine to move over 2 inches from the outside of the first circle and cut a second one? Both lined up on the X axis.

Thanks,

Billy

Hi,

Billy here. I am more or less totally new to CNC. I have a Sherline 4 axis mill. I just ordered a new controller and Mach3 software from a supplier in New York. I assume the Mach3 license will arrive with the rest of the parts.  It should arrive soon. The current computer is running Linux and EMC. It is old and I decided to replace it with a windows machine.

I downloaded a demo copy of Mach3 and have been writing some test programs to cut circles and squares and such. At the moment I am trying to learn gcode. I build vacuum tube guitar amps and need to cut squares and circles in the chassis. I managed to muddle through that on a couple of chassis with the old EMC software.

I am a old guy with lots of time to learn this stuff. It is kinda fun most of the time but a bit hard to figure out at times. I am sure I will have a few questions for you guys as time go on.

I also have in mind to build a cnc machine to control a Oxy/Acetylene torch to cut thick steel parts.
