Hi,
I have got ringing/underextrusion problems on my snapmaker artisan. The problem only occours in the direction of the x-axis (picture).
I`ve already done calibration of the extruder e steps. Furthermore I’ve also made tests with different acceleration and speed values, but the issue persisted in all of them.
Maybe someone in this forum can help me find a solution.
Welcome to the community!
What material did you print?- I guess PLA so, whats your print temperature?
What other settings did you use?- Especially speed is interesting.
Did you really need to calibrate the e-steps on the dual extruder toolhead?- What was your change? (Just wondering, my e-steps are on point with my 2.0)
If you look at your printer while printing, is the filament spool freely spinning or is your extruder dragging the filament hardly around?
After all these questions, first i would print a temp tower to be sure the printed temperatures are on point.
Vibration Compensation should be available on the Artisan so the ringing could maybe further optimized if its needed 
One question: The upper picture looks considerably darker: is this exposure (camera), or did you use two different filaments? I hope it is two different filaments because then explanation is easier 
Your print parameters are not good for the second brand But even then the problem looks strange… I guess my first try would be to raise the temperature slightly - 5°C or so. The circle parts where the problem occurs are those where the nozzle for the longest time is farer away from the bulk of the print, meaning it is getting the most cool air. If you are already printing at the low end of temperatures this might just bring you across the “too cool” limit. A point in favour of this theory would be that the air flow when printing in X would come from both sides, while the print in Y would partly block the part cooling fan’s air flow.
Hi, thanks for your fast reply.
@xchrisd
Forgot to mention, but you guessed it right: the used filament was PLA, printed at 210°C. Already did a temperature tower to find out which temperature works best. I’m using cardboard spools, but they are running ok i think. The extruder also doesn’t make clicking noises while printing.
I didn’t know about vibration compensation. How do I enable it?
@Hauke
I took the pictures with my phone in the same location but somehow the upper one came out way darker, but they are from the same part:
Thank you both for your ideas.
Ringing is not the main problem I want to figure out right now.
If you want so you could take a look in the gcode wiki M493 but the underextrusion is more noteable .
Please answer the other questions like settings especially print speed, extruder calibration,… (Please see my first post above)
What do you discover when you observe this print? (Is your nozzle raising because of spool counterforce?)
How does this print look inside?
