Greetings from Switzerland,
I am using a Modix 120X large scale printer with an E3D supervolcano and a 1mm nozzle to produce a prototype using cura 4.7.1. I have been tweaking the setting for a couple of weeks to get acceptable results with sufficient printing speeds (currently ~120g/h). However, the hopefully last remaining problems remain a mystery to me. To summarize them:
-irregular blobs on the inside of my object
-slight blobs, like tongues at the front layers
-irregular extrusion at the beginning of a new layer, as if there were bubbles in my hotend
-after finishing a layer with the infill, the nozzle does not move directly to start a new layer. Instead, it completes a very jittery, almost spasmic motion after lifting and across the already printed part. I believe this shaking motion plays a role in the aforementioned bubbles. Here is a vid of this.
My complete settings can be found here. Ive attached some pictures of the problematic regions. I do not have a picture of the bubbles currently, as this also appears to be an irregular event.
Happily looking forward to suggestions on how to remedy these nuisances,
Cheers !
