How to make a tool changer move to home

[edit]
Which GUI are you using? Axis or gmoccapy?

Thanks
Here is the remap:-


This is the complere config:-

You know what, let's do a little experiment. Open your linuxcnc.var file and add parameter 5400 to the end of the parameter list:
Like so:

Then start linuxcnc and load a tool. When you close Linuxcnc it should save the current tool number in the var file beside the parameter number 5400. Now start linuxCNC again and see if the toolnumber shows up in the status section.

I use gmoccapy and that loads the last used tool automatically.

5383 0.000000 5384 0.000000 5385 0.000000 5386 0.000000 5387 0.000000 5388 0.000000 5389 0.000000 5390 0.000000 5400 0.000000

OK Yes put 5400 into the var file and Yes on shutdown it shows the tool number in the var file.

but on start up the var file shows the tool number BUT you still have to input the tool into the MDI for the first run.

ie if it was tool 5 that showed in the var but if you then ran code with a different tool it would fail. Unless you had entered tool 5 at the start

Ok. So as for the message you could put this into your .hal file:

This should pop up a message in Axis after joint 0 is homed.

Do you want the tool to get loaded automatically when you start up or do you just want to be reminded to load the correct one (ie the one displayed in the status section?

loadrt message names=msg.checktool messages="Check ATC for proper tool!" addf msg.checktool servo-thread net msg-checktool <= halui.joint.0.is-homed => msg.checktool.trigger

This should pop up a message in Axis after joint 0 is homed.

There is already a msg that pops up saying something like load the tool number that is in place first.
This is after homing :-


So it would be good if it could load the tool number from the var file at start up after homing

This is what happens to the status bar after putting M6T2 in MDI


Then when any code is run it is fine even if different code is loaded as the system keeps track ok

So after starting linuxcnc we could maybe issue:

Can you try that in MDI after starting linuxcnc and see how that works?

T#5400 M6

Ok started with T1 in position homed then issued T#5400 M6 got the normal moment of the X and Z but No rotation of the turret. Status bar says NO TOOL checked the var value = 0

Then put m6t1 in MDI (no movement) Status bar says TOOL 1 checked the var value = 0

Then put m6t2 in MDI went to T2 Status bar says TOOL 2 checked the var value = 1

Then put m6t5 in MDI went to T5 Status bar says TOOL 2 checked the var value = 2

Shut down. and checked var file value = 5

Restarted-- var = 5. Homed . var = 5 Status = NO TOOL then issued T#5400 M6 got the normal moment of the X and Z but no rotation of the turret. Status bar says NO TOOL checked the var value = 0

Then put m6t5 in MDI went to T5 Status bar says TOOL 5 checked the var value = 0

Then put M6T6 in MDI went to T6 Status bar says TOOL 6 checked the var value = 5

Shut down VAR=6

Does the above help

A bit wierd if you ask me. You want to try gmoccapy gui? It's all built in there I gather.

[edit]

need to have a look at it on a sim config tomorrow.

[edit2]
Just had an idea, instead of T#5400 M6 try:
[edit3]
just came across this:
forum.linuxcnc.org/38-general-linuxcnc-q...mory?start=10#130061
This looks like a very clever way of doing exactly what you want, I hope. It basically gets the M6 routine to write it's own subroutine for the next startup in a separate file in your config.

I am not happy with gmoccapy as I don't seem to get on with it and all the machines that I have done are Axis gui

Was you thinking about this one :- forum.linuxcnc.org/38-general-linuxcnc-q...mory?start=20#131272

or A Pugh forum.linuxcnc.org/38-general-linuxcnc-q...mory?start=10#130062

But If it can't be done then I will have to remember to input the tool at start-up.

I think we'll get it working with axis gui. See edit2 and -3 above.

So try the m61 q#5400 and report back.
