I purchased the above rotary attachment and I am having trouble with smooth performance on my Co2 laser machine.

Between lines the movement seems to be a bit jerky and causes rounded edges of engravings to be jagged. I have a smaller 80mm chuck rotary that does not exhibit this issue. At time of purchase I was told that this would be appropriate for my CO2 laser. Is there any way to smooth out the movement to remove the jaggedness on rounded edges? I have tried multiple micro step settings to no avail.

Thank you for the information. Do you have a suggestion regarding micro step settings form my rotary. It has a leedshine dm860 controller and a 86CM45 stepper. I have the amps set to 6
