Joe's 1000x600x200 steel and aluminium router started

I've had this many times with the AM882 and the EM806 and it's a random thing, it's like they must put something in backward...Lol

Regards the Step edge then I'm not so sure because while I've had many drives be on the wrong side of the edge I never actually checked which was at fault, the controller, or the drive. I just do a quick back n forth check with g-code and if it drops steps then flip it over. I do this on every machine regardless if the drive and controller say they match or not.!

Thanks for clarifying Jazz. All 4 drives I have here behave the same way, opposite to the manual. Possibly there are multiple versions of the firmware floating around.

Will do the test for step edge, does it lose a step everytime the axis reverses, i.e. I should be able to test it as creep on a DTI at either end of the stroke?

Yes it drops a step every direction change. I just zero the axis put DTI on it and do 200-300 small G0 moves, 5mm or so, with the last move back to zero.
