Please add tool change command support. #330

GRBL does not support M6 tool change command. However Candle processes G-code before sending it to machine. So it would be good to interpret M6 in incoming G-code as spindle stop, then up Z-axis to some value (it should be defined in settings) and set pause. So we could perform manual tool change and then resume G-code sendig since then.

Would love to see this added, as well as custom variables.

I just came to post the same proposal. So I am joining in.

WIth FlatCam generated Gcode (Excellon) files, these toolchanges already work like a charm!

Alternatively you could try to add toolchanges manually in your Gcode files: look for any G00 Z<safeHeightVar> or G01 Z<safeHeightVar>, count these events and add a couple of lines at appropriate places: 

G00 Z<toolChangeHeight> 
M06

GRBL does not recognize tool change command, thus if that is contained in g-code Candle just pops up error message. All you can do is click to ignore and continue.

What is needed is Candle to make a pause, let user jog spindle in safe space, change tool, reset Z and then continue work.

OK, IC: Z-leveling option is not availlable in the scenario that FlatCam produces.

Please, somebody, develop the feature ;)

I have g-codes in my program that work fine for tool changes but cannot figure out how to reset the Z axis after the tool change. Any help would be appreciated.

I would love to see this work as well.
