Hi Darryl,

The E-Stop button is wired directly to the breakout board then configured within Mach3,  Ports & Pins / Input Signals. It basically has the same function as the on-screen Reset button.

Technically, E-Stop should be a latching multi-pole switch - which, as well as stopping Mach3 execution also disconnects power to the machine and applies brakes if appropriate although this is seldom implemented in the home-shop environment.

Hi Belin,

I am perhaps bit of an oddball in the way I do things but I set-up the CAD/CAM engraving work with the X and Y zero's (datum) at the centre of the work.
It is easy enough to locate the centre of the first blank by pencil drawing corner to corner diagonals, the blank is then located on a vacuum table in a corner jig and the centre located by a small laser cross-hair. The Mach3 DRO's are then zeroed and engraving then begins, replacing the finished work with a new blank in the jig, the batch is then completed.

There are many threads here on the forum which discuss various methods and a search should reveal the details but, if it's any help, there is a description of what I have done here http://www.cooperman.talktalk.net/files/17.htm

Share Your GCode / Re: Demo Gcode

« on: October 12, 2012, 02:35:15 AM »

Hi Guys,

Here is a little project that falls within the 500 line limit for the Demo version of Mach3.

I am going back a few years but this is probably the first item I made with my CNC machine after it was built.
The GCode was produced with the free software G-Simple (sadly no longer available).

The cube was made from 1.8mm thick engraving laminate and cut with a 2mm dia. Endmill – the 6 pieces then slotted together and fixed with cyano super glue.

There are 2 versions of ‘Tweakie’s CNC Cube’ and I have included the Gcode for each in the .zip folder in post #1 of this thread.

Hi Niroleta,

I am pleased that you are making good progress with setting up your new machine.

( Your English is excellent and 100% better than my French  )

how to calculate?

Hi Niroleta,

That’s the next thing to do when you have the machine moving under Mach3 control.

Rather than repeat the instructions here…

If you refer to Section 5.5 of the Mach3 Manual http://www.machsupport.com/documentation.php (I assume the French Manual has the same Section numbers) this details how steps are calculated manually. Then Section 5.5.2.3 details the automated process which is probably best for your machine with it’s reduction pulleys and drive belts etc. This process is then repeated for each axis in turn.

Hope this helps.

Hi Darryl,

This CNC stuff is going to be an adventure with much to learn but it will certainly keep the brain active.

I am going back a few years but this is probably the first item I made with my CNC machine.
The GCode was produced with the free software G-Simple http://www.gsimple.eu/

It was made from 1.8mm thick engraving laminate and cut with a 2mm dia. Endmill – the 6 pieces then slotted together and fixed with cyano super glue.

The cube has no practical purpose but if you want to give it a try the GCode file is attached.

Hi Niroleta,

The Velocity and Acceleration in Config / Motor Tuning may need adjusting for optimum performance, but it may be OK as it is.
You need to check your E-Stop and Limit Switches are connected to the correct pins and function correctly.

Other that that you should be on your way to making great things. 

Good fortune with your new machine.

Download a copy of the CNC611.xml (from your previous link) then copy that .xml into your Mach3 folder. That will take care of the configuration settings

You then need to create a new desktop shortcut to Mach3 (or modify your existing one) so that the Target is something like C:\Mach3\Mach3.exe/pCNC611
This new shortcut should then be used to launch Mach3.

Hi Niroleta,

I would need to see a copy of the manual to determine the correct pins for the configuration. If you could email me the Italian copy I will try to translate it.
