Stage 2, Step 3: I can't find Precision Shim for the Roller Wheels

Thanks a lot Chris! You are right!

it's not tagged in any bag. it's in a bag with out any label on it. they look like loose washers. they are about the size of the M3 or M4 washers. once installed between the bearings you might need to center them with a toothpick, pen or something. as they move off center easily. if i remember correctly they were in the bag with the eccentric nuts for the tool carriage
