I have a Prusa MK4 printer .Use the OctoPI
OctoPrint ver 1.10.3
I try to print a big file about 35M after some hours got the error
"SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)"
I run it on WIN11 pc
PI 4 with 1g memory with no install apps on it except the OctoPI
don 't use any camera or other devices
I have a fan working and I try to touch the Pi and it is not worm
the PS is from AliExpress but it suppose to deliver 3A
I attach the file octoprint-systeminfo-20241225212316.zip (3.7 MB)
Any help? Doron
I don't remember the exact message but I have an Alfawise U30 3D printer that is connected to octoprint and I encounter the same kind of problem. I finally saw that in the terminal window of octoprint that it's the same line is causing the problem.
In my case, it was :
G1 F2162.2 X129.502 Y14.729 Z10.1 E3165.10859
I have changed it to :
G1 F2162.2
G1 X129.502 Y14.729
G1 Z10.1
G1 E3165.10859
I have done the same reformating for the other similar lines and the printing is now OK.
May be this can help.
