Hi Ron,

Thanks for the reply. So what happens with Linear is that whenever it moves outward it does the "backlash hokey-cokey" by moving "2 * Step Size" further outward than needed, then when that completes, it moves inward by "2 * Step Size". Step Size does get changed by the algorithm but it will never be bigger than the Initial Step Size field on screen. So, for example, if Initial Step Size = 40, then it will correct for 80 ticks of backlash... if you have, say 100 ticks of backlash, then 20 will be uncorrected.

With Linear 1 Pass there will be 2 ways to deal with backlash:
1. Same as Linear (if on-screen backlash field is set to zero).
2. User entered backlash into on-screen backlash field. The hokey-cokey will be use this value. So in the above example, if your real backlash is, say 100, then set the field to 200 and you'll be fine.

Hopefully this would fix your issue.

John.
