Hi Art, Brian, and All
I went back and reinstalled Mach3R2.0.005 in a sub/dir Mach3R2.0.005 clean install once more, configured for rotational A axis as follows.
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 - Ports & Pins, for 4 axis and MPG# 1
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.
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.
Could a little-bit of code be added some-where, If ToolPath Page is set to Rotational, Even If Setting's Page, Rotation Diameters are set to 0.0000 to Default to Proper Rotational View..
The answer, Sure no problem, I hope.
I now, why didn't you say this in the first Place, still having some problem's with, Getting a Tool Path Showing Just Yellow Dash-ed Box snowing size for View Tool Path Window's, usually after Editing Gcode, Clicking View Screen for straight on view or Re-Gen of ToolPath, even before the A axis install.
I've spent several day's off & on with all of this, You no the Guy with the Cave-Man Gcode missing in Mach3.
Just trying to take a tooth-pick out of the gear-train hear, every-once-in-a-while.
Best Regards, Chip
