ok, sounds good. The file is .5 mm flat mill bit, .3125 radius <.625 diameter rod>
I tried cutting again with z axis reduced by 50%. I only made it 80% through layer one. Then the machine stopped rotating. It was moving the numbers for rotations, but not actually rotating, when the rotation numbers would stop, then x would kick in and it would go across, then do the a rotation again but not physically moving, then x would move across again, over and over again.
I checked diagnostics, had yellow home light on. I went to inputs and checked off A home output. Light went away. I jogged bit up. I jogged A, it won't move up. I jogged a down, moves down fine. I sped up jog rate. I can jog down the a axis all the way around and keep going. Then I can jog it all the way back up around until it gets to 315 degree mark, then it won't go more. It will go all the way around one way but not the other. I checked homing limits, A is set at 9999, so that looks good to me, kinda says to me there is no limit on A. But A is acting like it's at the end. If I jog Down the A all the way around and keep going, so lets say 500 degrees. I can jog it back up 500 degrees until it gets to that 315 point and then it's stuck. Makes me wonder, is there a limit as to how many rotations the A can go physically inside the unit? Like it's got a worm gear inside that is at the end, and so I have to just jog it back a couple full revolutions to get that gear in the middle? Makes sense but makes no sense to me at all, I would think the A could rotate in either direction indefinitely.
