Gmoccapy & carousel.comp problems after update was created by Trav328
Unsure where to post this so feel free to move to a more relevant section.
for the past year this machone has been working perfectly using gmoccapy and carousel.comp on linuxcnc 2.9.2

Yesterday I updated to 2.9.3 and the latest gmoccapy and after a couple little bugs it's all working fine except my toolchanger , when commanding a toolchange though mdi it will home the tool changer like it should , then select the desired tool , but after that calling up a new tool only changes the offset and does not operate the tool changer.

Here is a short clip so you can see what I'm talking about.

Debian 12 , linuxcnc 2.9.3 , whatever the latest gmoccapy is. Updated yesterday.

Did you check HAL pins in Halshow?

Yes , I also forgot I have this in gmoccapy_postgui.hal.

 

looking in halshow everything related to carousel seems to be functioning fine using my tool change jog buttons, its as if ive lost communication between gmoccapy and carousel , but only after the forst tool selection.

Looking through some more pins , for that first tool change where it works through m code , iocontrol.0.tool-change triggers , it goes to the desired tool then iocontrol.0.tool-changed triggers and stays triggered , then I am no longer able to do any m6 tool changes

If I unlink this pin and manually clear it I am able to do another tool change , then manually set and clear I can do another and so on.

It seems to be that the iocontrol.0.tool-changed is no longer clearing itself.

Seems that 'carousel.comp' has not changed from 2.9.2 to 2.9.3:
github.com/LinuxCNC/linuxcnc/compare/v2.9.2...v2.9.3

I _think_ it's normal for 'iocontrol.0.tool-changed' to stay true.
Question: Does 'iocontrol.0.tool-change' go false?

I have read that there has been no changes to the carousel.comp , I'm thinking it has to be somewhere else.

When doing the 1 tool change it will do upon startup iocontrol.0.tool-change goes true then back to false and will not go true again.

Here is a video showing that.

I presume you are not using the gmoccapy tool change dialog so I don't see why gmoccapy would need to play any role in this and indeed looking at the halfile you attached and comparing that to the screen shot of your postgui_halfile it seems that the signals in the postgui_halfile are actually not connected to anything (which I think is correct):
net tool-change iocontrol.0.tool-change => carousel.0.enable
net tool-changed iocontrol.0.tool-changed <= carousel.0.ready 
net tool-number iocontrol.0.tool-prep-number => carousel.0.pocket-number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

The question is why the MDI toolchange does not seem to work after the first change.
Maybe you could test if it works properly if you use a gcode file. If that also fails to work after the first change then it is not likely to be related to gmoccapy at all.

So my suggestions are:
- Test in a sim config on your machine
- Test with your machine config using a gcode file

I just went out to the shop and ran a program , it behaves exactly the same , the offsets and tool number chnage but the physical tool does not , then the program just continues on.

Im not sure what you mean by try in a sim.

I have noticed this since the update aswell , possibly related to something missing or out of place ? , the first time i open linux cnc it starts in some odd configuration,  notice the 5 decimal places and world mode at the bottom,  then I have to close and re open to continue.

Try to run one of the Gmoccapy simulation configs for lathe located in 'configs/sim/gmoccapy/lathe_configs'.
