Hi Fernando,

I don't know when the problem first crept in but it is unlikely to ever be fixed.  I have found that with G2/G3 circles using a lead-in (created in CAD/CAM), with the same radius as the arc, allows the knife blade to rotate whilst clear of the work - it increases the overall process time but resolves the problem for me.

There is but one Mach2 version for download under the FTP Downloads tab on this page http://www.machsupport.com/software/downloads-updates/

The trial version of Cut2D does not let you generate Gcode from your own files only the sample files provided by Vectric (this is all explained in their documentation).

Perhaps, as an alternative you may like to consider the free program G-Simple.

LazyCam (Beta) / Re: help lazycam to G code

Sorry to say this but LazyCam is probably not the best tool for you to be using. The unlicensed version of LazyCam does not handle tool radius offset compensation so the part would have to be drawn in CAD with the outside dimensions 'tool radius' larger and the holes 'tool radius' smaller to achieve the desired results. 

A better solution would perhaps be to use a different software such as Vectric Cut2D (or similar) which would automatically apply tool radius compensation to the generated Gcode.

Hi Goingnuts,

I am pleased you have the problem sorted.

Hi Poppy Ann,

Guess that was the name of your sailboat ?

Mach3 is free to download and use but it has a number of limitations (eg. only running a Gcode program of 500 lines). Once you have tried it and are satisfied that it will run your machine as you require then you can purchase the license which then removes the limitions mentioned above.

The license can be obtained here http://www.machsupport.com/licensing/

Thanks to Khalid for his work on machine embroidery  - I finally decided that I had to give this a try.
Just running a Tajima test pattern and ignoring thread colour changes my machine set-up appears to be running OK so I can now start to investigate the software side of things, hopefully to create my own designs.

An ‘Active Low’ signal is normally high (approx. 3.3V or 5V) and goes low (0V) when it is enabled.
It is the opposite for ‘Active High’ they are low (0V) and go high (approx. 3.3V or 5V) when enabled.

As said, your motors should ‘lock’ when the board is powered-up (irrespective of any combination of step and direction pin settings / allocations) so you need to find which pin or pins provide the Enable signal / signals. It will, of course, be one or more of the Output pins 1-9, 14, 16, 17.
Try them each in turn first active high then active low – when you can’t rotate any of the stepper motors then you have found the pin / pins and it’s / their active state.
Then you can proceed to confirm which are the correct step and direction pins for each axis (although I think you already know that but check again to be sure).
