spindle rotation based on tool number was created by jbunch
I have a backtool lathe. Is there a way to change the rotation of the spindle based on tool selection.

Hi
There is always a way!
How do you change tools currently?

eg
..
G28
M5
M3T3
G43
M4 (or M3 whichever suits)
..
I was thinking that you had an ATC where cutting tools and drills required different rotation (ie slant bed lathe).
It would be possible to alter the manual_tool_change component to do similar, but if you are changing the toolholder / tool by hand anyway, not clear about any advantage.
Or, are you actually asking about a toolchange component for your lathe (have just seen on your profile you DO have a slant bed lathe)

In which case would it not be easiest to do it in gcode?Manual tool change.

I guess you could use high tool numbers for clockwise and low for anticlockwise, then get clever with HAL and the iocontrol.0.tool-number pin.I have a backtool lathe. Is there a way to change the rotation of the spindle based on tool selection.
