Z lift option for retraction

[repetier]

Including z-lift in ops is difficult. Had so far no idea how to do it correctly, because I need to break up the move in 3 parts.

If you lose steps in combination with z-moves check jerk-z and reduce it. There was also a case where a jerk didn't get adjusted correctly. Don't know if t was already corrected in the last version or the upcoming, so make sure you have the latest version. The code in question is in Repetier.pde and should look like this:

inline float safeSpeed(PrintLine _p) {
float safe = printer_state.maxJerk_0.5;
if(p->dir & 64) {
if(abs(p->speedZ)>printer_state.maxZJerk_0.5) {
float safe2 = printer_state.maxZJerk_0.5*p->fullSpeed/abs(p->speedZ);
if(safe2<safe) safe = safe2;
}
}
return (safe<p->fullSpeed?safe:p->fullSpeed);
}

With the Host problem, try the newest version 0.51. There the counter problem should be fixed.

The code you mentioned is not in your repository yet. Thanks for your help !

safefullSpeed is not declared in the current version of Repetier.pde ... I need your full version of the file to be uploaded to the repository !

No, it was a problem with github. There was a smaller sign which was interpreted as tag start. Updated the code above that is is now printed correct.

Finally, moving forward or backward the max Z-jerk value does not change anything to my problem... Moreover I lost Y-axis steps while not using the Z-lift option. This was related to my pololu max current config which - for an unknown reason - changed. You can close this issue.
