Good day!
I propose several improvements in the management of fans, incl. from panel due.

1. Add a total ban on changing the fan power from g-code.
2. Add a soft ban - do not reduce less than a manually set value.

Ok. Wait for next version....

Doctor, they ignore me!

Good afternoon!!
Tell me how to properly configure the printer so that there are no artifacts in the PanelDue.
Problem:
After adding the y-splitter and, accordingly, 2 tools per 1 heater, the tools began to display incorrectly on the panel.
At the same time, the web-interface works correctly.

but it not work in panel due

Good day!
I propose several improvements in the management of fans, incl. from panel due.

1. Add a total ban on changing the fan power from g-code.
2. Add a soft ban - do not reduce less than a manually set value.

Tool offset work fine, thanks! Tested on 2.03RC1

I confirm the problems with the Wifi connection in 2.03RC1. In combination with HTTP + FTP, the connection was extremely unstable, it was impossible to transfer files over hundreds of bytes either via http or ftp.
Editing config.g to disable ftp caused it to self-delete when writing.
Recovered on sd card from backup.
In the only http mode, it became possible to record files, but the recording speed dropped 10 times.

I try to delete M82 - no effect.

@anidal said in A bug in 2.02:

M82 ;absolute extrusion mode

In macros and printable file coordinate X228 Y245 is not present.
Is it possible that the macro command M82 is missing in the macros, but is it present in the print file and is somehow affected?

Good day.
I disabled the restart of the printer from stop.g and tried your commands.
At this point, the printer completed printing the model, completed stop.g, turned off the power, and only + 5V PS_ON is active.
