In process of purchasing a 94 Makino rmc-A10 with 10 tool tool changer. Previous owner had 2 of these machines one with the tool changer and one without. An employee accidentally cleared all of the parameters on the machine with the tool changer. At the time they were unable to find a full set of parameters that would also include the tool changer parameters, so they copied the parameters from the machine without the tool changer and put it onto machine with the tool changer. Ever since the tool changer has not worked. It also worked perfectly before the parameters were cleared. Also need programming manual etc for the machine. Machine works great as it is but it would be so nice if the tool changer worked.
