I'm sorry for no reply before. but now I have a new issues,. By mistake I pressed the erase button of the underboard display. from this moment the display is in black, I've tryed to reinstall the display firmware with Bossa, without results, and if all of this is not enough, the IP diretion has changed.
For all of this, I can't conect with the printer. I tryed to change the Ip in the config.g , but no works.
I'm inside a black hole.

This is my config.g, created at https://configurator.reprapfirmware.org/Start, on 18/12/3.
I'm unable to see anyting wrong...0_1544091246022_config.g

Thanks alot for your quick response.
Effectively the lines M665 & M666 no appears.
I have see than the Last modification of the config-override is unknown.
As you can see in the secuence of screen captures, seem that the config-override is overwrirted, every time that i restart the electronics.
I Tryed as well, to make M500 and M501 without restart, with the same results.
I thing that is clear the M501 overwrite the config-override

Hi all.
I have a little problem with my duet wifi. I have working with it for three months. and understanding how it works. It works fine. but from the last month i cant update my config.override.
I decides to Clear all my system and install the new 2.02RC5. no problem all works fine, except than after autocalibration (delta), I store with M500 or M500 P31, and It saves the delta parameters. But when i restart, the paramters are gone.
I have the M501 at the end in the config.g.
I dont understand what is wrong.
Any sugestion?.
Thanks in advance
