I'm confused about the acceleration parameters. In the hal file. setp stepgen.1.maxaccel [AXIS_1]STEPGEN_MAXACCEL Which comes from the ini file. MAX_VELOCITY = 3.3 MAX_ACCELERATION = 15.0 STEPGEN_MAXACCEL = 35.0 What I'm finding is if I do a G00 X5 It accelerates very quickly. But if I use the jog buttons on the AXIS screen it takes a really long time to get there. It's even worse with the 4th axis. Fairly quick with G00 A360 from say 0 for one complete turn. But it's not even up to speed by the time one turn has been done. These values aren't that much different. MAX_VELOCITY = 180.00 MAX_ACCELERATION = 720.0 STEPGEN_MAXACCEL = 900.00 I'm missing something but where? Thanks John "ELS!
