"Error: No Tool selected" Upon seemingly successlful toolchange

Diamondback

Hello,

I'm running into an interesting issue with my custom toolchanger.

Upon commanding toolchanges with T0/T1, it executes everything as expected, unloads the current tool if one is loaded, then loads the new tool etc. DWC indicates that the newly selected tool is active.

However, after each change, I get an error message: "Error: No tool selected" despite the toolchange seemingly being successful.

I also get that very same error right after startup (I do not have any T commands in my config.g)

Startup:

power up + 00:00:00 [info] G10 P0 X-9 Y39 Z-5

post a set of tool change files.

Can't see anything wrong there. Just for completeness, are you also willing to share your lock, unlock and movetodock macros?

Diamondback

Sure, nothing fancy to see there:

jay_s_uk

can you comment out line 120 (T-1) in your config.g
that should eliminate the startup issue as no tool will be loaded at startup unless you tell it to.

you don't have anything odd in the config.g for the filament do you?

Diamondback

@jay_s_uk Wow, totally missed that command
However, it doesn't change anything, I still get the No Tool error on startup and toolchange.

Filament configs literally only include a retraction settings call, nothing else (and no filaments are loaded atm)

Diamondback

Upon further watching, it appears that the "No Tool selected" actually pops up between toolchanges, ie after storing away one and before picking up the next.

~~@dc42 can you tell me which specific actions would spawn the "Error: No Tool selected" message for console/popup?~~

Edit: Found the problem. It was calls to M703 in tpreN.g, I guess since the tool isn't technically loaded there yet, it can't apply the correct filament settings.
Moved the calls to tpostN.g as well as removing the M703 from config.g and it works now
