Under Extrusion pattern on wall Hi i have a problem what im fightin from some time, i already try a couple of things. 1) Increasing extruder stepper curent 2) Decreasing retraction and detraction speed 3) Increasing extruder spring tension 4) Replace nozzle and silicone tubbing not nothing seam to help :( im using SlicerPe, i attahed my current settings, screens, stl and gcode in zip file [attachment 104421 problem.zip] I record also how my extruder works [youtu.be] This is a picture of issue [attachment 104423 30729987_1771273679604437_4214176671944671232_n.jpg] [attachment 104424 screen.jpg] [attachment 104422 IMG_20180416_133721887_LL1.jpg] https://reprap.org/forum/read.php?262,819252,819252#msg-819252 Mon, 14 Sep 2026 01:09:50 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,819252,819261#msg-819261 Re: Under Extrusion pattern on wall https://reprap.org/forum/read.php?262,819252,819261#msg-819261 I had mine reversed at one time and showed the same thing.]]> Floyd Printing Wed, 18 Apr 2018 20:27:19 -0400 https://reprap.org/forum/read.php?262,819252,819259#msg-819259 Re: Under Extrusion pattern on wall https://reprap.org/forum/read.php?262,819252,819259#msg-819259 That can happen with PETG often enough, less likely with PLA unless your temp is high.

if you have your temp as low as possible while still being able to print, then increase your non print move speed a bit.
increase your retraction and detraction speed leave the retraction distance low, 1-2mm likely is good
reload a little more filament when detracting to compensate for what was lost during the non print move. There should be a setting in your slicer for this.]]> JustSumGuy Printing Wed, 18 Apr 2018 19:33:38 -0400 https://reprap.org/forum/read.php?262,819252,819252#msg-819252 Under Extrusion pattern on wall https://reprap.org/forum/read.php?262,819252,819252#msg-819252
1) Increasing extruder stepper curent
2) Decreasing retraction and detraction speed
3) Increasing extruder spring tension
4) Replace nozzle and silicone tubbing

not nothing seam to help :(
im using SlicerPe, i attahed my current settings, screens, stl and gcode in zip file
