I guess it is supposed to be a big secret than as to piece mealing it all together. or maybe my question is vague? I have been looking to build a router since I tore down some old scanners and printers and wanted something to do with the motors in them. that was about six months ago. Started looking on the internet for different rig assemblies and I have found alot and alot of how-to's nothing seems to really give the specs of the electronics portion of these yes they seem to list the motor specs but nothing as to boards. Im just trying to get an idea as to if I buy a board off of say ebay and than later buy the motors what are my chances of the board and the motors working together. and will the board work with most software that is out there. mdfly on ebay has some boards but on of the post on here doesnt sound promising as to them working correctly. any help..
