Garand

Oh, just for record: I found another way! Z hop when retracted ON Z hop Height = Same as the layer height ( In my case 0.12 or 0.24) My z hop height was 2 for the 0.12 layer height and 0.3 for the 0.24 layer height, when I changed to Same as the layer height, the weird lines were gone!

@gr5 Oh, I didn't know about that I'm just a few months inside the 3d printing world, but loving it, specially because the community support! I asked about not using the z-hop cause makers muse once showed a x-mas tree that failed due to no z-hop, but now I believe it was an exception... About the support, yes it's the ps4 logo! Thanks for the tip! I'll remove the supports for the next print. I believe my problem is solved at this time then! Thanks @gr5 and @burtoogle

Hmmm. Thanks for the analysis! So, there is anyway to have z-hop on all layers or should I just stop using z-hop? At this time, I haven't seen any difference on the test prints i'm running to check the problem, the quality seems the same and looks like no aesthetic difference (with and without z hop).

@burtoogle Sorry, I meant disappear on the GCode preview, i'm printing at this time a test to confirm that.

@gr5 This one: CE3_PS4_Controller_Stand.gcode This is after I updated the profile from where I get them from: CE3_PS4_Controller_Stand3.gcode Same STL After updating the profile, one of the layers has gone, but two of them remain there. If I deactivate the z hop, all of them disappear.

PS4_Controller_Stand.stl @gr5

@burtoogle Ender 3 Pro Maximum Z-hop speed looks like it's 10mm/s. I don't know about the jerk, but in the profile i'm using it's 8mm/s.

@gr5 I found it:

@burtoogle I am printing to see if deactivating the z-hop will make real difference. The difference made was on the GCode preview. But, what do you think of these settings?: Z hop Speed 10mm/s Z hop when rectrated - yes Z hop height 0.4mm These are for the 0.12 profile

At this time, i'm printing a Abraham Lincoln Bust with and without Z hop, when they're done, I tell the results.

Hello @gr5! I would agree with your options 1) 2) and #2, but they don't explain why going back to Cura 4.3 made those lines disappear... About #1, shouldn't that happen with every print I make, Since it's a ''mechanic'' issue? I'm not finding the gcode (probably replaced with an 4.3 cura sliced gcode by mistake) for the blue part, but when I saw the first time and compared with the print, the lines were exactly in the same spots. About the Z Hop, do you have any ideias about that?

Hey there @burtoogle! That's the catch, when I print it, those lines appears on. The deal is that only IdeaMaker is showing the problem... The printer is an ender 3 Pro and I 100% sure that there is no z wobble or extrusion problems because I sliced the same file on cura 4.3 and it printed Ok as every GCode viewer showed (including IdeaMaker. Ps: I spent the night setting up the profile and I found that when Z Hop is on, the damned lines appear, no matter what other option is on, including combing. I've checked the light speed problem and the speeds are ok. Ps2: I have no photo of the Deadpool, but here is one of a controller support that came with the same issue. (Cura said it was a ok and IdeaMaker showed the lines when I opened the Cura GCode):

Hey there! I just updated to Cura 4.4 and I started having issues. Some faulty lines on outer walls that are made by Cura but they don't appear on the preview. I found that the problem is on the GCode after opening the GCode on IdeaMaker slicer... Those lines appears on the printed thing too, and are very weird. :( I have checked the stl on Win 3dBuilder and NetFabb and no problems were found, then I sliced other stl's and the same problem happened... I'm new to this forum, but as far I've searched, nothing like that has appeared. The stl is attached. deadpool_withSupportsfix.stldeadpool_withSupports.stl CE3_deadpool_withSupportsfix.gcode Thanks in advance.
