Was searching for similar topic but could not find it. I am putting it here in case someone gets the same issue. For a while, here and there (not always) i would get wrong Finish position after job is done. Mostly i want Finish position to be same as start (user origin). In some jobs i flip parts over so i can engrave them from other side and i count on last position to be same so everything is nice and aligned with no need of setting Origin again and again for each job. I am working with Lightburn, so i thought there is some missaligment with Ray. Yesterday i was close to Ray while movingnin G0 and in one moment when G0 was done i heard different sound before it stopped (like axis skipping sound). And yes, after checking i saw that finish position was missaligned in X direction by some 10-15mm. It seems that the weight of 40W laser module is such that it can cause slipping of axis (probably high inertia) on G0 move. I went into machine settings in Lightburn and set Max. X movement value to the same as for Y, which is like half less. I dont need super fast G0, but i really need to be able to count on stable positioning.

Did someone else have similar problems? I havent checked on Luban if G0 feed is the same value as in Lightburn. Could there be some other issue that i didnt thought of?

Thanks for suggestions.

What is your fast whitespace scan in Lightburn set at?
