Recently my prints with curves in them and when printing via Octopi I can watch/hear the head pause, especially when going around curves. I also see all kinds of zits being produced.
I took the same gcode and copied it to SD and printed it from there. Still, a few zits but nothing compared to the Octopi print.
Used Cura 4.4.1 to create the gcode.
I did calibrate the extruder and it is spot on.
I lowered the outer wall speed to 30mm (from 50)
I read on one of the boards that the serial port speed on the pi & ender serial port is to low so that it stops while waiting for Gcode, which is the pauses I hear (sounds like chatter)
I don't know if this is related to latest Cura and how it's generating gcode for curves.
I did not have serial logging turned on. I turned it on.
I should have known to try safemode. I ran in safemode and it is printing fine. I will run another print with all the plug ins enabled except thespaghettidetective and see what happens. Then enable thespaghettidetective and see what happens.
I am looking forward to how you get on with this, I have the same issues, to the point I have given up using octoprint. I have enabled serial logs, but no idea where to find them or Id share them with you, I have tried safe mode and no different, so sd card printing from now on, such a shame!
Safe mode created great prints. Run normal mode without Spaghetti Detective and the prints had just a few zits. I cranked up retraction distance to 10 and retraction speed to 60 and that helped as well.
