Don't be too hard on your self there are many more who have done the same with same results.!

Ok well the video doesn't help much. I'm hoping the sound is exagerated due to being filmed on a phone because if not then you have other issues to address.? As in why does it sound like coal train.!!

Regards Mach3 then it's not true that these machines will only work on Re-skinned version. Mach3 doesn't use skins and provided you know or can workout the pin configurations for drives, limits etc then will work with just about any machine. The problems are more to do with the fact the chinese are using a Old Copied version of Mach3 which is known to be bad.
There are a few Chinese machines which use a USB controller which does require a Plug-in to work with mach3(As does every other external controller). These can give you trouble if they only work with early versions of mach3. In this case you have to download the relavant version from Artsofts FTP download site.
This said you have movement so must have a Plug-in if using USB.

To help more we need more information about your setup. Provide plenty of pics.
Post the Mach3 XML file your using. You'll find it in the Mach3 folder with same name as the profile your using with the extension XML. You will have to Zip it up to post it.
From this we can see your settings which should show if any thing is set wrong in Mach3.
