Where did you get your top load for this project?

Thanks Stephen. I’m also curious what steps per unit you ended up using in Mach3 and how you came about that number?

great articles, thanks

Hi Stephen

The code looks great; but every time I try and download the zip from GitHub and decompress it, the zip archive is invalid. I’ve tried this on a few machines now so it’s a problem with the source at GitHub and not something odd I’m doing

Any chance you could zip the code and mail it to me, or upload it somewhere else temporarily?

Many thanks,

Richard.

I actually etched some PCB to match and then used a spring clip to hold the flat cable against it.

How did you end up making electrical connections to the flexible flat cable? Direct solder?

I’m about to go this route…

Not that I’m aware of – I can’t really give you a better answer, I don’t actively work with the drone any more – not looked at the code for over a year.

Thank you Stephen,

I continued to have the same problem and since the problem kept pointing to the speechRecognizer I decided to plug a microphone into the computer and enable the Windows Speech Recognition system and that fixed the problem. Now I can use either the executable, or the build from the source files. Does this program use voice recognition for inputs?

Just off the top of my head I would say that the 64-bit has something to do with it. The errors you describe are very “generic” – Invalid Operation, rather than “File Not Found”, or “Out of Memory”. I would try building as a 32-bit application.
