    You are correct in that it is banging at the ends of the x raster. I have not had a chance to test out the slow corner speed settings but once I do, will report back.

    So it has been quite some time but I am almost back up and running again. I tested the slow corner slows idea and it did soften things up. I had to lower it significantly, I went all the way to 20 for a rounding gadget toolpathe using multiple strategies as tests. All banged back and forth at the ends of the X raster until I lowered the SCS as mentioned. So I can only assume I have some other whacked out ramp setting. I run my machine pretty snappy usually so I'll have to do some more investigating.

    On an unrelated note. I reset my config file and lost my unit values that shopbot gave me a while back. Now they cannot figure what they should be and i have no confidence in the accuracy of the 4th axis rotation. Also of course I did not save the file before loading a different one. Whoops.

    What are you running for a gearbox (ratio) and motor? If it is the 12" one, IIRC it is something like a 15:1 planetary Neugart or something + an AS911 motor?

    Post up the gearbox plate specs and motor label specs.

    It is the 10:1 motor bought from shopbot directly for a 6" indexer. image.jpg

    On the driver itself, are all the little switches to the LEFT?

    What is the multiplier for the B axis in VR?

    In VD is the B axis set to degrees or linear/inches?

    On the driver, all the small white switches are to the left. Mimage.jpgove and jog speed for B axis are both 10.16.

    Under VD, b axis rotary, A axis is linear 0.
