First thanks for the reply.
About communication, I have a Duet 2 Wifi (32 bits) using the card that is on the motherboard. I've had cases of this stuttering, but here the files are all on the same SD, under the same conditions, one hangs and the other doesn't. So I believe it's not the printer, but some cura configuration, because with 5.2.1 is running normally.
Attached is the print of the "Mesh Fixes" of version 5.2.1 and 5.3.0
