Feedback loop following error

I was asking about the connections inside HAL. 

Here are my are HAL and INI files. I set the margins of the following error to way too big for the jogging i do. I move it 5 mm and i still get error, if the min_error is 10mm it shouldn't trigger right? 

Any glaring mistakes in the files?

Is it also possible that the backlash in the system does something?

For initial tuning, I would set the following error limits very large
(both at 25 mm or so) so they never trip unless you get a runaway
and then set all pid maxerrors to 0

setp pid.x.maxerror 0
setp pid.y.maxerror 0
setp pid.z.maxerror 0

What if i just comment them? Would that work as well? I did that I now realised I uploaded an old version.

Okay, so after some work on the machine turns out that I have a following error because the encoder doesn't tell the machine to stop. The stepgen position is relatively okay (+/- 0.2 mm) (so the stepscale is fine), and the encoder count position is also okay +/- 1 count (0.005 mm). So why doesn't the encoder tell the axis to stop? I set following error 25 mm and if i move it 1mm it stops on 24mm (following error). What parameters do i check to see if the motor is taking commands from the encoder feedback? I didn't provide a f-error halscope because i see no point in that at the moment because the PID parameters have 0 effect on the movement (i tried to mess with them a little but to no effect). Please help!
