I am new to 3D printing, I have a Creality ender 3 Pro with bl Touch installed.
motherboard 4.2.2 and Bios Merlin 1.1.2 from 2020.4.25.
I have Octoprint Version 1.5.2 installed from "octopi-buster-lite-0.17.0" on a 4 GB Raspberry pi 4.
The prints go perfectly well through the micro SD.
On the other hand as soon as I go through Octoprint I have this message displayed:
Critical resend ratio!
16% of transmitted lines have triggered resend requests. The communication with the printer is unreliable and this will cause print artefacts and failures.
Please see this FAQ entry on tips on how to solve this.
and it results in the printing of blockages, and large stain of material
What should I do to correct this problem?
Thanks in advance for any help!
