Ok guys, I was someone who didn't read the forum before purchasing a power mate, so hooked it up and realized the plugin was old. Difference was, that I'm a programmer, so I downloaded the plugin wizard, and coded a plugin for it. It's pretty simplistic, but it works.
I requires the .net framework version 3.5 since it was done using the plugin wizard, and if you don't have that or don't install that, then Mach 3 will tell you that your plugin is damaged. Anyway, here is the dll.
Hope it works well for everyone. It basically just steps the axis by .001, and I haven't tried it with millimeters, so let me know how well or badly that works. Clicking it changes axis just like the other broken plugin, but since nothing else on the other plugin worked for me, I don't know what else it did.
I know this is raw, but if people like it, I can probably find time to make it better.
