Subroutine with Toolchange

I have written several ngcgui subroutines to use with a Sherline lathe and mill. In the subroutines I issue a T<n>M6 code. When using the lathe, the tool information is loaded into memory and execution of the subroutine continues without pausing for confirmation. On the mill, the subroutine hangs--apparently waiting for acknowledgement that the tool has been changed. Everything works as expected using a sim configuration.

The lathe uses the core_stepper.hal file; the mill uses stepper_xyza.hal; of course, the sim configuration uses the core_sim,hal, axis_manualtoolchange.hal and simulated_home.hal files. I would like to get the mill to act like the lathe, picking up tool information without pausing the subroutine. Any thoughts?

Thanks!!

use halmeter to look at the iocontrol pins for toolchange handling:

www.linuxcnc.org/docs/2.5/html/config/emc2hal.html#_pins_3

tool-change
tool-changed

tool-prepare
tool-prepared

Are probably the one to look at first

It works. I made the assumption that standard_pinout.hal files were all the same. Not so! The hal file for the mill had two lines commented out that "create a signal for tool loading loopback." Simply uncommenting the two lines fixed the problem.

Thanks. You saved me many hours.
