For some reason, I keep getting these little zits and holes across my print using Cura on my Prusa MK3S. I have a feeling it is a simple solution, but it's difficult to pick out the one setting that will fix it. They primarily form on concave/convex overhangs, but are also visible on vertical walls. I'm thinking maybe retraction. Additionally, there are these little ripples in the center of the picture. They appear specifically there, on all 3 faces around the print that are identical. I'm using Esun PLA, fresh roll, dried, 210C, tried printing from sd card and octoprint, outer wall speed is 30mm/s, acc/jerk is stock Prusa MK3S settings, aligned z seam, no coasting, no outer wipe. I can print the same model in PS with just a little artifacting in the overhang and no ripples on the side.

Sure, here you go. Funnel.3mf

I'm trying to print a part that uses support near the top. However, I get a few of these little bits that are generated on the buildplate. Support blockers don't do anything and I can't get rid of them for the life of me. Any good way to block them?

I ran a test with set M104 S160 and M140 S65 constants as an attempt to remove variables when the first layer variables would have been. This is what was generated up to the first layer. It added M104 and M140 values before the start code. But then the M109 and M190 are completely ignored and the leveling begins ```` ;FLAVOR:Marlin ;TIME:228 ;Filament used: 0.104057m ;Layer height: 0.2 ;MINX:113.024 ;MINY:99.024 ;MINZ:0.2 ;MAXX:136.976 ;MAXY:110.976 ;MAXZ:15.2 ;LINEARADVANCEPROCESSED ;Generated with Cura_SteamEngine 4.5.0 M140 S65 M104 S215 M82 ;absolute extrusion mode M115 U3.8.1 ; tell printer latest fw version G21 ; set units to millimeters G90 ; use absolute positioning M82 ; absolute extrusion mode G28 ; Home M104 S160 ; set extruder temp to 160C M140 S65 ; set bed temp M109 S160 ; wait for extruder temp M190 S65 ; wait for bed temp G80 ; mesh bed leveling M104 S220 ; set extruder temp M109 S220 ; wait for extruder temp G92 E0.0 ; reset extruder distance position G1 Y-3.0 F1000.0 ; go outside print area G1 X60.0 E9.0 F1000.0 ; intro line G1 X100.0 E21.5 F1000.0 ; intro line G92 E0.0 ; reset extruder distance position M907 E500 ; Set motor current G92 E0 G92 E0 G1 F2100 E-0.6 ;LAYER_COUNT:86 M900 K30.000000 T0 ;added by LinearAdvanceSettingPlugin Edit: I found the solution to the main problem. I needed to use G28 W instead of G28, so the bed leveling doesn't occur before the preheat. Now I'm not sure why I'm getting the couple of lines before the start code. That is the final mystery that needs to be solved.

I'm not sure why, but I can't get the starting gcode to work how I want it to. I simply want to home, preheat the nozzle to 160C, and heat the bed to the desired temp. However, I feel like I'm telling a toddler to do 5 things and it will do a couple things, out of order. With the code below, it begins preheating the nozzle to 160, then immediatly mesh bed levels. It doesn't home and wait nor does it even attempt to heat the bed.
