Was worried I was loosing steps because I was trying to run too quickly approx 2500mm/s rapids (with a 1000mm/s cuttuing speed and a small DOC),

Pretty sure you must mean 2500(mm/min), not (mm/s) if not then that's your problem right there...Lol

Whoops, of course.




Ps. To all of you, you absolute legends. Tried jazz's test after adjusting the step polarity. Seemed OK... Attempted the same pocket, absolutely perfect!


Few mins later and we have half a chain adjuster!

Over the moon, cheers guys!

Good stuff - nice to know that that was the problem! One of those things that can really worry you but with a trivial fix - once you know what it is... I lost a lot of sleep over that one when it happened to me, until eventually I discovered that the error was exactly equal to the size of one microstep times number of direction changes (I think, with apologies to m_c if my memory is playing tricks - I think I only lost one step per direction change).
