@jay_s_uk thank you for the enormous help you're giving me, I'd like to take advantage of it again, to know now I'm using IR probe, can I leave that to do the 0 on the z-axis? and use the sensor probe to do the mesh plane check? THANK YOU

@jens55 @Phaedrux ok it worked, thanks to your observation I found out that my router which is an enterprise, assigns not only the MAC but also a card ID, and for him the MAC should not change every change is an attempt of unauthorised entry and since the mac changed it put it in bad list, now everything worked .. thanks again

@jens55 OK thanks for the answer I'll give it a try

@phaedrux thanks for the reply I'll try Friday with the usb cable ... but even if the MAC address changes and this could be the problem since my router is set up with armoured macs, if the mac changes it is not enabled to the network, but I would still see it trying to access, which does not happen and in any case I set a fixed ip on the config.g and even if the mac changes it should keep the IP assigned by code, if this is not the case then it is a bug in the code that does not keep IP, i.e. I have not enabled DHCP

no the update seems to go well ...when the card resets at the end of the update, the web page should restart but it doesn't connect anymore, and it doesn't change the ip ...I have the control router and it doesn't turn out to be connected to anything and the printer doesn't respond to anything it remains black in the screen, it's as if the update didn't go well or as if the update beyond 3. 3 is not compatible, if I reinstall the firmware 3.3 I find myself with the web updated to 3.4 but I can't load the firmware even with the later versions it doesn't accept more than 3.3

hello

I have updated my Duet 3 Mainboard 6HC from version 3.1.1 to the actual 3.2 . 3.3 all okk always without problems via DWC web interface , from version 3.3 to version 3.4 stable ... everything loads correctly, is asked to update .. and after a few seconds resets as usual, but does not restart, I have to use bossa to be able to reinstall the firmware version 3.3 version 3.4 or later does not want to accept it in any way

What can I do to try to update it ?

thanks

ok .. in the meantime I try this solution thanks

ok, thanks ... in the meantime I have done other tests, unfortunately the same thing always happens .. heat the dish ... then it goes into the home with the boards and then heats the extruder. this at the moment as already said at the time of the axes, having the extruder still cold detaches the piece from the plate bringing it into the home ... and then letting it warm up .. and correctly starting from the point of printing left .. but unfortunately the piece below no longer exists

this is script generate
