Extruder stutters when retracting
-
Hi all!
My somewhat DIY printer is set up with Duet ethernet and DueX5, Kraken hotend and Titan extruders powered by a MeanWell 24V PSU.
I have a problem with audible stuttering when rectracting, it is not everytime but quite often. I have tried to swap stepper driver output, new cable to stepper, swapped stepper motor and changed bowden tube. Same issue remains. I'm only running one hotend/extruder now btw.My rectraction setting are 3mm & 40mm/s right now, but slower and faster are tried.
I have uploaded a small video here (sound are better if you download the video and view it offline)
It stutters on the last few retractions in this video:

I'm not really sure what is your problem ... maybe you can decrease the jerk or/and acceleration settings from the extruder to solve this what you want.

Can you post your config.g and the results of an M122?
At first glance of the video is seems ok to me. Maybe I'm not seeing it clearly enough.

Well, it turn out to be a "feature" and not an error.. It does stutter but it is because I have "retract while wiping" on and 2mm wipe around small corners gives this kind of behaviour.
The main reason I asked about this is because I have an issue with some layers bulging, like overextruding or something. Going to start a new thread about it.
