How to get rid of these blobs on your Prints

I noticed it, it was on a vase where the wall was printed in a spiral, so theoretically at a constant speed of the print head without any retractions or similar.
time, where again, the built-up pressure in the bowden extrusion system lead to the blobs.
is a really nice and smooth vase. But here’s actually the problem because during slicing each of the facets will be translated into one linear move, resulting in a lot of very small motions.
and starts stuttering. If the individual moves are too small and have even seen it happening with Octoprint that wasn’t able to stream movement commands fast enough for gyroid infill.
commands fast enough. So at some point, the machine starts to slow down and, in this case, extrudes a little wider due to the pressure in the system.
feeddrate would always be constant. Direct extruders are a bit better in that regard.
tiny and also, the Ender 3 prints the same G-Code fla wless.
into one. If they are below a specified length, effectively reducing the size of the G-Code file and making moves more smoothly.
 and activate “maximum resolution” and “maximum deviation”.

error that is allowed by this simplification.
maximum deviation in cura
also allow smaller print moves. which is for deviation, an okay value but for the resolution pretty small.

to 1200 commands per second, which will definitely overload the processor, at least the old 8bit ones.
a maximum resolution 10 times as big, the Ultimaker 5S even sets it to 0.7mm!

I sliced Buddy once with the stock 0.05mm resolution and once at the resolution that the Ultimaker 3 also uses which is 0.5mm.

have a length in a specific range. For example 0.12 to 0.14mm or 0.4 to 0.42mm.
especially because the model itself was really fine to begin with.
is? It’s our wipe distance of 0.4mm. Pretty cool.
see that the peak has moved from 0.16mm to the assigned 0.5mm.
in the file size of the G-Code but in the end, the proof of the pudding is in the eating or rather here, the printing of the G-Code.
nd also all of the zits on Buddy are gone, so we’ve really succeeded.
especially for deviation. In my case, I couldn’t see a negative impact on print quality with the 0.5mm value that I used.
case really be more evident because the firmware of the Alfawise seems to be acting up a little, but if you have strange phenomena during printing and notice that the moves are not smooth, try playing around with that parameter and you might be surprised about the results!
and if so, what your results were and which values you can recommend!
