HI
Had this same issue yesterday on a machine im retrofitting.
I have a crude workaround that seems to be working...
M6 is remapped to do the toolchange using the .ngc program. When the tool is
changed, i update a paremeter #5000 with the new tool number. #5000 was
added to the .var file
I then added a MDI_command to the .ini file : M61 Q#5000
And i issue the MDI command when the machine is on and homed. I did this
using classicladder, with machine-is-on, x-is-homed, y-is-homed, and z-is
homed all in series, with a monostable to pulse the output and the mdi
command is then excecuted.
You can do this in hal as well with a couple of and2 and oneshot components.
Regards
Henk

Hey guys.
I got a fixed position toolchanger using Andy's carousel component.
Just need to remember the tool in spindle before shutdown
When you set toolchanger as random io control remembers the last tool when
you restart. And that works perfectly for a few years on another machine.
But this machine I'm having issues with.
I found that this is a pretty common problem.
Hoping it's been fixed by now and would love to know how people get around
it if it's not fixed yet.
https://forum.linuxcnc.org/49-basic-configuration/31150-current-tool-number-
permanent?start=10
And Todd Zuercher had a interesting idea I saw maybe using a random
toolchanger setup and tricking it.
Also I think Andy got it working but would appreciate some clarification on
what people managed to get working
Anyway hoping someone can help cheers
