Hi Everyone, I contacted Shopbot , and in the process of bringing this Shopbot back to life after it had been stored in a barn for several yrs. It went together easy and all rollers look good and the table squared up easy. I talked to shopbot and they looked the numbers up on the old pc and said it was a 2006 PRT standard and it has the newer rails. I received the new RBK control box yesterday and going with the router instead of the Spindle for now. I had been reading some of the problems some of you have had with the spindle. Some of the questions i have Shopbot said this motors that came with the machine will work. On the wiring diagram it says to use motor ASM98AT.7.2. The motors that came with the machine are in the picture at the top. They are A6497-9412KTG, 2 phase/ 0.5/step/. I am going to get an electrician to hook it up but is this the only box needed. I noticed in some of the pictures of the machines there is another box outside of the RBK that is smaller and has lights on it. I did not know if this new box took care of all that. I was looking at the wiring diagram and it has an input voltage of 120 v on the drawing to connect to the Main Disconnect. I am sure that the Electrician will know but if he has a question . Does 120V run the complete RBK control Box. The router has a plug on it and i was wondering if it had to have its own source of power. I did not know if a plug needs to be mounted to the side of the y carriage . It looks like from the wiring diagram it ties into the contactor so it will shut down if you hit the stop switch. One more question where is the best location to mount the RBK so all the wires will reach. I am going to take my time on this, it is best to do it right the first time and not have to go back and do it again. Thanks everyone for any input you can give me.
