Hello everybody, I got my SVO6 in the end of January and since then i have this problem. My prints are looking like this when the lines are not straight. And the start of a layer is sometimes lacking of material. ![IMG_20230512_171155](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/1/1cf4e427ddc3d2cde9ea90dc51c7fc35fee7c741.jpeg) It’s my first time printing with PETG. But I have the same problems withs PLA. I lubed every bearing when i got the printer and adjusted the steps of every motor. I’m using Cura right now and tried different settings. I also worked with different belt tensions But nothing worked so far. ---

It looks like under extrusion. Did you set the retraction distance to 0.5 & retraction speed to 40.0…?? Also it could be cause by using too low of a nozzle temp. PLA: 210\*-215\* PETG: 235\*-240\*
