Does that mean it can work with PCIe Mesa cards?

Probably not for Debian 12. It makes no sense for us to upload that to
Debian (if they would even want it) as the LinuxCNC version of the
hostmot2 code is rather outdated and the repository is archived.

You _could_ download the version from LinuxCNC, but they are only
there for buster and earlier:
http://www.linuxcnc.org/dists/buster/base/binary-all/ )

But, the most up-to-date firmwares are direct from Mesa:

PCI Express! Better power supply! That's the two things that I was most 
impressed by...

Another option that springs to mind would be a Python userspace component.

On first loading it would load the last-loaded tool from a file
(possibly the .VAR file, possibly a special single-purpose file) then
sit in a loop waiting for "ready for MDI" (which is easier to do in
Python than HAL) and then issue the M61 command.
It would then sleep, with a callback on the "shutdown" message, at
which point it would save the current tool to disc. (Or, maybe, it
would just sit there polling the tool number all the time and saving
it when it changed.

The only advantage of this is that it's a load-and-forget. It needs no
HAL connections or external logic.

But, really, this should be built-in behaviour.

Re: [Emc-users] Remembering the last tool in spindle before restart (andrew beck)

[andrew beck]

hey henk

i got it working also today just copied this on the forum worked
perfectly and the toolchanger works great still just have to clean up a few
rough edges but it changes tools and remembers the tool in spindle after a
restart

i want to make a video tomorrow and maybe help the next guy.  i will make a
overview of my setup i think.

O sub
M6
#4999 = #5400
O endsub
m2



MDI_COMMAND = M61 Q#4999 in ini
and
net machine_enabled halui.mdi-command-00 in Hal

thanks for the reply.

cheers andrew

[Emc-users] Remembering the last tool in spindle before restart (andrew beck)

[hdpreez2]

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.

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
