It would make things a lot easier for new users to properly wire the device and get the most out of it. Some enjoy trial and error and testing, but others may be afraid of breaking something or not have the time to invest in it. I would imagine as turn key as possible would increase sales and popularity. DIY, that's the majority of the customer base for this, right? The larger the information base, more comfortable the user and ultimately, a deciding factor in picking a motion control device.
Look forward to seeing this info. Really enjoying the Pokeys57cnc and have several projects this would fit nicely into.
