Wait a second, this configuration looks wrong to me.
In the HAL file your steplen and stepspace are both 2500 ns, so that
gives a max step rate of 20,000 steps/second. But you set
stepgen.position-scale to 40,000 steps/inch and stepgen.maxvel to 10
inches/second, that's 400K steps/second!
In the INI file you tell the trajectory planner (i think) that it can
ask for a maxvel of 4.8 inches/second, which is 192K steps/second. Of
course you're going to get following errors!
I'd expect your setup works fine up to 0.5 inches/second (20K
steps/second), and gets following errors when trying to go faster than that.
