Hi Art,
I used Tempest to great effect cutting the 'New Hub' file in aluminium, the finish was great despite it taking nearly twice as long but as I said earlier, for me time is not a major issue. However, I am about to cut a couple of temporary wing moulds from MDF and have attached one of the files here. When I use Tempest, the roughing cut, from the start to line 7398 cuts rather hesitantly. The accelerations are smooth but there is a massive difference in speed throughout the cut and the machine seems to almost stop at times. When compared to standard Mach, there is no comparison, standard Mach machines this far better. When it comes to the 'Parallel Lace' operation, line 9814, the reverse is true and Tempest performs far better than standard Mach.
I am using settings of 1 for smoothing and 25000 for jerk. The cutting speeds seem high but I am only taking small cuts from MDF.
Mike
