This sounds like a fairly simple configuration to set up with Stepconf, which I would guess you have already tried to run, which is why you are asking about the accel and velocity. It is probably best to work that out in the Stepconf axis-test screen, keep increasing both until you get a stall then reduce by a factor to allow for some margin. (And if it stalls with your first guess, make the numbers half the size). You will probably find that you can get higher peak speeds with lower acceleration, but for intricate shapes like it sounds as though you intend to work on you might find that acceleration is more important than top speed. Stepconf has built-in timing data for the Keling drives. As a starting point, looking in the Sherline sample configs, in inch units, velocity is 0.36 and accel is 2. Your machine looks a bit bigger, and so can probably go a bit faster. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
