Hi Craig!

Thanks for your kind recommendation and suggestion, and also for going out of your way to explain the procedure that I could try. I'll definitely follow that suggestion and try it out. I'll update you with the findings. Also, thanks for mentioning other possibilities, such as possible Mach 3 involvement. I'll explore that avenue.

I'll definitely be uploading some pics of my setup very soon. One thing that just came to mind is the relatively long 3 mm diameter drill bit that I use for drilling the registration holes. I think they're around 5cm long bits.  Maybe that could have something to do with it. I did order some shorter ones, so I will do some tests with shorter drill bits. I will definitely report on the findings with spare pcb blanks .... with drill holes at the corners of a square shaped pattern. Thanks again Craig. Much appreciated.

Very cool!  Nice machine!

Backlash is functional in Mach3, never tested it with version 66, does work in 62.
I echo Jerry's reply ............ And if you are using a motion controller, it's possible that it doesn't support backlash comp.

BTW, Try setting a large value for backlash ( say .1" ) with a slow shuttle wheel and  backlash speed setting.

Ger21,

Many thanks again,
you have been of great help.
Now finally things are beginning to work.

Regards.

Hi,
you have bought a USB connected external motion controller of dubious origin with no manufacturer support.
The issues you are having are not Mach3 issues and unless you are fortunate enough to find someone on the forum who
has extensive experience with that particular board then you will get exactly what you paid for.....not much.

Should you consider replacing what you have or want another unit then carefully consider products by Warp9 Tech Design, CNCDrive
and PoKeys. All three enjoy industry leading reputation for support.

I agree, Unfortunately i did not realise i was ordering from a place with no support.
Thanks.

I have tried adjusting the backlash compensation and suttle wheel amount but they seam to have zero effect.  Absolutely no change regardless of values entered for either.

Oops. I failed to notice that you were unable to run the code as a single monolithic program, so my reference to your file name is irrelevant. 

I was running it on my office PC using the Simulator and had no issues. If you are unable to do that, it sounds as if your installation may be bad for some reason.

Here's a manual:

https://www.buildyourcnc.com/Documents/USB%20Motion%20Card%20STB4100%20Manual.pdf

Works here using version 3805.

You haven't slipped in a zero in place of O, or added an extension to the file name?

Allan?

have you tryed to run your M12 Version with

Config -> General Config -> Ignore M calls while loading    enabled?
