M2nano specs

M2nano specs

Searching for some information on the M2nano, I came across these specs;
MAX:600mm/S Carving:7mm/S Cutting:0.5mm/S X-Axis Motor:0.33A/Phase Y-Axis Motor: 0.44A/Phase

These numbers give a good reference for what is possible and better with a third party controller and software.

I know Bonne Wilce brought this up in passing but as the software improves and more people are using it, I am sure the users would be willing to donate a monthly amount for the use of the software. A single dollar/euro/(more than a few) rands/pounds a month would be a great start for most. A lot of the sites I frequent put it this way, "...a few dollars/euros/(more than a few) rands/pounds a month is the same as a single beer, so why not buy your coder a cold beer once a month!" Most people would be happy to have an automated payment taken out monthly or even yearly.
