Change direction problem

at the moment I'm faced with the following problem:
By doing a relief router makes fast direction changes.
And.. it seems that at this action it looses steps. Is that possible, that this can happen?

The "direction force" is already activated, but seems not help enough.

Problem is, that I'm not sure if this is really the reason.

To speed up work I first tried to have a relativ high basic speed an a low acceleration.. now I try it the other way.
"Relativ" means in that case that machine could do much more - if I could teach it somehow to slow down at fast direction changes.

I found a delay time under options "dir/step" (or similar - not sitting in front), which has a value in ┬Ás. Could I use it somehow? Not what for it is.

Do you use speed override (checkbox next to speed slider)? If you do then don't?
Do you have backlash set in settings? If you do then you need to enable "Lookahead/Split Arcs" and "Lookahead/Direction change".
Perhaps you just need to set "Lookahead/Angle" to 170.

Hello Andrej,

no, I do not use overdrive, no backlash used, but I use the "force" button for the direction change (but I do not know which decelleration it uses) - I will try the "lookahead angle" of 170, I think it is 150 now - then it wouldn't have additional effect - right?

I have a new Broadway Limited EMD NW2 with a Quantum QSI decoder. If I change direction without going to 0 on the speed it causes a momentary short. If I go to 0, then change direction it is OK. Is this a malfunction or do I have something set wrong?
