I absolutely did get that manual, and will definitely be printing it out, as well as many other things regarding the Chinese router setup. I want hard copies of the manual from you and printouts of every mach3 setting page as they are now. Currently, I have tap water as coolant, will likely be switching it to a distilled water/antifreeze mix, unless you have a better suggestion? I belong to several CNC groups on Facebook and will go create a post to let anyone with a similar router know I have the solution to the spindle issue if they need it. Thanks!.....................BTW, I have seen lots of talk about something called a breakout board. Can you tell me what that is, and if I would have to have one?.........
