Hi

I will be able to test your config later, but I suspect I have found the problem.

# loadusr -W hal_manualtoolchange
loadusr -W hal_manualtoolchange_jog

net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared


You have renamed the component file to hal_manualtoolchange_jog

Unless you have edited the component code to rename the component to the same name,
it will launch the component which is still called hal_manualtoolchange and wait for ever for a component called hal_manualtoolchange_jog to become ready, which it never will.

Then it would error anyway because iocontrol is still linked to hal_manualtoolchange

Revert to the original name and it should work

regards

Yep, that is exactly what is wrong with it

Changed it back to original name and

Great thank you! I just tested it, and it's working for me too.

I'd spent plenty of time looking at the code, but never would have thought about the filename.

This will make life easier to be able to jog during manual tool changes.

Cheers,
Luke

Hello...

Till now I use the old branded machine. (EMC2 - it's works so I didn't change)
But now I make another one for a friend. And component doesn't work as should.

When M6 is executed the popup window is shown. And I happily change tool and make Z touchoff.
When I press continue tha machine start immediatly with spindle OFF!

So how to add spindle on and to wait spindle-at-speed signal (my spindle make slow ramping to reach speed)
Of course I can start spindle manualy after changing and wait enought to startup before click continue..
...but preffer automatic!.

Hi

I just do it in G Code if I want the spindle stopped and re-started

...
M5
G28
M6T2
M3
G4 P10
...

There are so many different types of toolchanger, with a lot not wanting the spindle stopped (almost all lathes), coding it is probably easiest

Maybe this is good option as in most cases when tool is changed the spindle speed is changed too.

I know this is a pretty old post, but I'm having the same issues as you were Gold Boarder. Can you share your latest config files? I'm also curious to see how you setup the Auto, Manual and MDI HAL GUI. Thanks.

Can you describe exactly what problems you are having?

Ha (noob), realized that shortly after posting. I'm trying to get to where @eslavko is at (see below). I'm having the issue where linuxcnc is not letting me control the machine during this process. Also, I'm wondering if I should be going back to G53 (my home position) before the tool change instead of currently just raising the Z axis. I'm not sure how to do this exactly. Should I just run N90 G53 with no other parameters? I've attached an example of my current code.

Hi, robksawyer

It's been mentioned above - you need to change hal_manualtoolchange file (located at /usr/bin)
it's a Python script LinuxCNC calls when M6 command is issued.
My owm machine uses new hal_manualtoolchange (see attach) - it's a bit buggy with LinuxCNC 2.7 but works.

Your G53 question is pretty simple - you may add any code prior to toolchange in your postprocessor, or manually.
Just an example: raise Z, then move to machine coordinates X10 Y200. Do toolchange. Raise Z again to safe top.
... your actual milling code 
G0 G53 Z100
G0 G53 X10 Y200
M6 T5
G0 G53 Z100
... your actual milling code
