You were right, someone connected a zebra printer and his IP address was the same as the Duet Ethernet address, I changed the address and now everything works again.
Thank you very much for your answers.
Indeed, this printer does not have much interest but I want to make the above spiral as quickly as possible without everything while keeping a good precision. So I told myself, certainly wrongly ☺ , that a rotary table might have been necessary for such a task.
I will try to insert your methods and you will show the result if there is one. 😬
actually, I've never had an alarm before. I wanted to know if it wouldn't damage the engine pilots, but it doesn't seem to be the case.
Thank you very much for your answers
What I meant was that I tried on a corporate network and it didn't work, so I tried on my home network and it didn't work either. So I changed my DUET IP address to 192.168.1.202 and now DWT works fine.
Thank you for your reactivity and your precise answers.
