@Veti what do you mean?

@Veti that's how it is already imaged, but it still prints slowly

when I start the printer and click on homing, everything still works perfectly in terms of speed.
even if I operate the printer manually, there is still nothing going on until I put a file in it to print, then it suddenly becomes very slow.
then print it with 8mms and wait for a few seconds after each line before it continues

hello i have a question about my duet 2 wifi.

well after a while I didn't use my printer ender 3 pro anymore with a duet 2 wifi board.

well I wanted to print an x again but now print that maximum but with 8mm / s have already updated the firmware also on newly configured but nothing help.

can someone help maybe.

this is terrible
