Retraction - Where is USE_OPS

I am using repeteier 0.92.x . I cannot find fast retraction or USE_OPS. Has this been removed?

1. How do I do fast retraction in Repetier Host?

2. What values should I "calibrate"? REtraction speed? Retraction distance? Travel?

Thanks for any replies.


  • OPS has been removed, yes.

    You set retraction speed in slicer or if you use G10/G11 in firmware.
    You want fastest speed that does not cause problems with filament/extruder motor. Distance should be as small as possible, so make it just short enough to prevent stringing. Travel speed fast, but so it does not loose steps in any case.
