I have a Hurco VM1 and a Hurco VM20. When running the same programs on these 2 machines the VM1 completes the program as expected to the time provided on my CAM package. Where as the VM20 runs over by a considerable amount (almost double on some programs!). The machines are using the same post processor so I dont think its a CAM issue. Does any one have any suggestions on how to bring the VM20 program time back into line? I have briefly looked and compared some of the parameters between the 2 machines but I am not 100% sure what these parameters are controlling. Thanks in advance.
