Are you absolutely sure these are the files you are using? There are several problems, starting with the fact that the ini file only invokes two .hal files, but you posted five .hal files. That isn't a technical issue - you only need the two - but it just adds to the confusion. Technical problems: you have a max velocity of 1, which means 1 inch per second. You have a scale of 40000, which means 40,000 steps per inch. Combined, that means 40,000 steps per second. To do that, you would need a base period no longer than 12500 nanoseconds (which is very fast). You have 14000 nanoseconds (which is also quite fast, but not fast enough to get the speed you are asking for). I think you'll need to lower your top speed. Jeff Epler tried running the config, and got a following error, because of the speed limit, and/or an acceleration limit. He had to lower the max speed to 0.7 and raise STEPGEN_MAXACCEL to 45 just to get it to run. When he did that, the position commands are rock-stable.
