Hi, Steve
Have a sherline rot. table, read this below, you need to devide the 115200 by 360 enter this value in Step's Per in motor tunning, set the vel & Acll. up high.
Config - General Config - checked A-Axis is Angular, checked - Rot 360 rollover, checked - Ang Short Rot an G0.
Config - ToolPath Configuration - checked - A Rotations Enable, use Diameter for Feedrate.
Config - Motor Tuning, My A Rotational set-up 360 deg., set-up X,Y,Z, 40000 step's, 10.002 vel, A 1 Deg.=, 400.2 step's, 2500 vel, 144072 = 360 1 turn 144072 dev by 360 = 400.2
Re-Start, Mach3
Loaded Tooth1.txt Gcode file, No Rotational View Shows in Tool Path Window's, just linear view..
Regen Tool Path, Still No Rotational View, Gcode Shows Run Through, Jog A axis shows Degree Mode in Display.
Setting's Page, set Rotation Diameters A axis to 1.0000, Re-Gen ToolPath, OK, Now it shows Rotational View.
Default Start-up and Create New Profile or Closing Mach3 with a value of 0.0000 in the Setting's Page, Rotation Diameters on re-start will Default back to Linear View as it is now.
Hope this Helps Chip
