The Rw15 is still running strong, the ball was indeed from the vice, I have no idea how it indeded up falling out of the tool changer.
Other than the table being a little soft the only other issues that have popped up are as follows
on two occasions the tool changer has come flying out toward the spindle before the head is up far enough to clear , bent the door of the tool changer, milltronics sent out a new door a few days later.
Complained about the coolant pump breaker tripping while still in warranty, Milltronics offered to send out a new pump, I assumed since the problem was documented within warranty period that it would eventualy be replaced under warranty when it failed. I told them we would wait on the pump until it failed. Pump did finally fail outside of the warranty period , ask for the pump that was offered while still in warranty assumed it would be sent since warranty issue was documented , milltronics refused to replace , said I would have to purchase at my expense.
One of the home switches failed a few months ago , found a direct replacement on ebay NIB for $30 .
Overall happy with the machine, limit switch is a normal wear item, should have taken the coolant pump when offered , my mistake on that one.
Machine has been very accurate and made many thousands of beautiful parts , I have since purchased a new vf4 Haas and have been very happy with the haas controller in comparison with the Cent7 . Overall my only complaint with the Milltronics controller is it didnt come with USb or flash card reader and you cant easily scroll thru programming line by line and edit easily. Also have not figured out how to start from a tool change in the Milltronics.
Beyond these few fairly minor issues its been a great machine over the past 2 years and hopfully will remain so
