Manual Tool Change was created by Project_Hopeless
I have a file created in Fusion 360. I believe my program is stopping on the T1 M6 command, manual tool change? But I'm not getting a message dialog to indicate tool change.
(SPOILBOARD)
(1ST ATTEMP AT SPOIL BOARD)
(T1  D=6.35 CR=0. - ZMIN=-19. - FLAT END MILL)
N10 G90 G94 G17 G91.1
N15 G21
N20 G53 G0 Z0.  <<<<<<<<<<executes this line then stops
(BORE1)
N25 T1 M6

I did not consciously setup for manual tool change. Is there some HAL or INI configuration you have to edit to have manual tool change?

yes you must configure a manual tool change prompt.
usually by loading and connecting to the hal_manualtoolchange component.

Not knowing more about your machine configuration, my guess is that it is actually pausing for the line "N25 T1 M6" which is commanding a tool change to tool #1. If you don't have a tool changer and your config isn't properly configured for not having one, or if you do have a tool changer and your configuration is somehow wrong regarding it, that is what happens. Without seeing your config files or knowing more about your machine, we are only guessing.

For manualtoolchange sometimes this solves in hal.

loadusr -W hal_manualtoolchange
net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

Thank-you I will give it a try.

Does it matter where in the HAL file these code lines are placed? This is copied to the main HAL file or postGUI.hal, or other?

Always at the bottom of the main hal file.
