octoprint slow and ugly - failed prints
hi, I have a little problem with octoprint and my mk3s (+ mmu2s) :
- first i noticed some weirdness (little holes in print as if nozzle was partially clogged, sometimes overextrusions, both disappear when printing from SD), high print time (same gcode took from 20 to 30% more time when printing via octoprint)
- I updated firmware to 3.10.0 (was on 3.9.1), updated octoprint too, and tested latest rc (1.7.0rc2 for low latency mode on the serial port function)
My recent problem is that my octoprints prints are at best slow, often slow + ugly or failed
- I checked "serial.log" : no error,
- compared it to gcode : no additional or removed lines
- checked cpu usage (searching for "lag spikes") : maxed @ 1200 MHz - 40/50% load
- checked temperatures (nozzle, bed, raspberry cpu) : normal
- tried to run octoprint in safe mode : same pb
the main difference i saw between SD print and octoprint is that with octoprint, even though the gcode is the same, the nozzle seem to "dive" into printed object (it doesn't raise up well and sometimes even go down)
Do you have any idea of what's going on ? (I suspected serial port / gcode stream throughput but it wouldn't cause nozzle to go down ...)
Bellow is included in zip a photo of SD and octoprint prints, gcode and logs if it can help.
edit
-> reuploaded gcode because the version i included in zip was the one i edited to compare to serial (comments, parameters, ... missing)
temporary solution
I completly reinstalled octoprint (full install of ocotpi on a new micro sd card)
-> uglyness disappeared
And to regain former speed I tweaked gcode to speed up gradually between layer 3 and 8 from 100% to 160% print speed (in printer settings, custom gcode, before layer gcode) :
{if layer_num >= 3}{if layer_num <= 8}M220 S1{(layer_num-2)*10}{endif}{endif}
OctoPrint forums may be the place to ask
You're likely to get more responses over on the OctoPrint forums for this sort of question. Your problems seem to be contained in your OctoPrint setup. My first question is what sort of RPi are you running this on?
