Hi Nick,

Welcome to the forum.

The first software that I started out with was G-Simple http://www.gsimple.eu/ it's pretty basic but it's free and may give you an initial start.

Hi John,

What an interesting device, I have not seen this before – but… I can’t help thinking that just one sneeze during tool setting could spell disaster.

Hi Carl,

Those Chinese TB6560 boards have been shown to be problematic (search otherTB6560 threads).

If you want quality and reliability then choose something like the Gecko G540 http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html (small price to pay compared to Aspire).

Hi Scgrove,

Welcome to the forum.

I don’t use Sheetcam (probably the best choice of software for you to use) but I do use Vectric.
I think you need to check your .dxf files for duplicate lines etc. and edit as necessary to get the drawing as you want it to be (origin etc.) then make sure the vectors are correctly joined before generating the GCode (the procedures are all detailed in the Vectric tutorials).

Hope this helps.

Hi PhillM,

Welcome to the forum.

The electrical noise produced by VFD’s can sometimes be difficult to control but here are a few suggestions…

All limit switch (and e-stop) wiring should be made with shielded cable and the shield only connected to GND at the controller end.
The cable connecting the VFD to the spindle should also be shielded.
It is good practice to have an EMI filter in line with the mains input to the VFD.
Try to keep the limit switch wiring distant from all the VFD wiring.
Treat GND and EARTH as being two separate circuits.
Check for and eliminate GND loops – It is best to have a star connection at the controller and take all GND connections to this one point only.
Check for and if possible eliminate EARTH loops.

There are many more potential noise elimination steps to follow but these are my initial thoughts.

Brett you may want to list all the known PIRATE license.

Hi Terry,

Perhaps that would not be a practical proposition as there are a couple (to my knowledge) pirate license generators floating about which will allow any chosen name to be used for the license creation.
