Thread: Colchester Master 2500 feed problems

28/02/2023 20:09:59

Help Please

New to me Colchester master 2500, runs very smoothly, everything seems in very good nick, but there is no rotation of the leadscrew when W and X is selected on the feed speed selector. V, Y and Z all work correctly, its just the two, meaning there is none of the usual slower feed speeds. Thread cutting all runs fine on all other settings. Any suggestions of what i might be stupidly missing much appreciated before i start delving into the gearbox.

Many thanks

James
