Just a thanks to all that cared. Problem solved. A simple case of over thinking the processs. I had to take a step backwards but long story short we had to loosen up some deviation tolerances and allow more arc code instead of linear.

Using Mastercam X4, couldnt find my " output feed move "? - BenK, are you guys also using G05 P10000 ?

Had'nt been able to try anything til this morning. Had to get some parts out as is, and in the mean time had to get the reps out here with continual coolant / filter issues. Any way, we tried the G05 P10000 and get an improper G code alarm ? The G5.1 will run it, but way slow as previously mentioned. Any more ideas I'm all ears. I'm also sending program to dealer to see if it will run in their floor model. Thanks again

Thanks for the info. I checked all that you mentioned. Everything appears to be in order. I am however a little sketchy on what the machine dynamics should read when I get into the feedrate smoothing and cornering. But gave that part of it my best educated guess. When it comes to the Makino and the Pro 5 do you know if we should use a G5.1 or a G5 P10000 or I believe there is even a G8 ?

Good day to all Our shop has recently purchased a Makino A51 HMC with the Pro 5 control and we are having some difficulties with the HSM. The program it is running ran fine in a 2003 Kitamura and also in a 2006 Robodrill Mate. The programmed feedrate is 500 I.P.M. and though never quite reached in either machine due to size of part it did get close. The same program in the Makino tops out at 60 I.P.M. and stays there ? I dont know if there is something we are overlooking in the machine control or if it is in Mastercams post ? Any ideas ? Thanks
