How to fix these errors?

[dintid]

I've begun getting the following errors and not sure how to fix it:

After each reconnect to the web interface:

[[language]]
Can't open 0:/sys/oem.json to read, error code 4

When changing to Tool 5:

T5
Can't open 0:/sys/tpre5.g to read, error code 4
Can't open 0:/sys/tpost5.g to read, error code 4

When changing to Tool 6:

T-1
Can't open 0:/sys/tfree6.g to read, error code 4
```and

T6
Can't open 0:/sys/tpre6.g to read, error code 4
Can't open 0:/sys/tpost6.g to read, error code 4

If you don't enable Platform debugging then those messages will go away. So:

• Check that you have no M111 command in config.g
• If you are using Repetier host, then there is a bunch of buttons in the UI, one of which will stop Repetier sending a M111 command to the printer. You can blame Repetier for implementing their own version of the P parameter after the P parameter had already been implemented in RRF and documented in the reprap.org gcode wiki. [It's not the first time Repetier has ignored a documented standard, they did it when they implemented tool mixing too.]

I have purposefully enabled debugging or I can't know what the problems are. I don't want to just disable these messages. I want to fix them, so should I manually create blank files, or?

I am not using Repetier. These error messages originaes from within the Duet Web interface.

What problems?

That looks like the ability to have tool change (pre - post) scripts per tool, outside a slicer.
Awesome!

Can't open 0:/sys/oem.json to read, error code 4

This was added by Christian to allow OEMs to have their own JSON file it is ignored if not found.

Can't open 0:/sys/tpost6.g to read, error code 4

If you have 6 tools defined then they will look for the free, pre and post files. If you don't want to carry out any actions on tool being freed up not pre and post a tool being selected then blank files are fine.

Can you give more information about the macro problem please.

Thank you for very nice answers in regards to behaviour of system. These explanations to standard warnings would be awesome to have in some centralized place.. either in Wiki under a dedicated section and/or in the Web inerface.

Macros:
We used to be able to click a macro-file in the webgui and choose run, edit or delete but not anymore. Now we can only select run it. We can't even delete it from inside the webinterface, but has to put the SD card into a computer.

You can right-click the files. I was confused at first, too, but now I kinda like it…
