Ah man you have to hurry up with that video! At least a teaser of the design concept?
Please let me know how those stepper drivers perform with that CNC shield on the Arduino, I actually have 3 Uno's just lying around at the moment (the university hands them out to us every semester) and I feel I should use at least one of them for something on my machine, just not sure what!
I was just checking the specs of those drivers, I didn't find any A489's so I assume you meant the A4988's but I noticed that they accept anything between 8-35V however you have a 48V power supply? Just want to make sure you don't fry anything!
Also perhaps ask a moderator to move this thread into the Wood Router Project Log section, should get more attention there
Cheers
Kevin
