Does this look good enough to continue printing?

I changed my nozzle to a 0.6mm and loaded up the cura profile from my other post that was provided by @azab2c . My filament that I was using was on the printer for quite a while so I cant imagine it is exactly perfect but I have a couple new rolls of dry filament awaiting.

Anyway, the LR4 instructions suggest printing the Z stub and Z nut to see if they go together, if not to print the calilantern (which i purchased). I have included the pictures of my stub and nut and want to know if the forums think that I should be good to go or not? They were tight fit originally but now go together quite nicely after a bit of connecting them together.

Thanks guys!

Looks like your Z offset is a little high. That first layer did not squish together. Might want to adjust that a little.

I did the z-offset using the paper test and bed/nozzle up to temp for PLA. I adjusted it until the paper scraped the nozzle well (-2.09). The first layer is on the underside of these pictures. I will get a better picture of that tomorrow. It looks really good as far as surface finish. Is there something specific you see to tell you the first layer didnt squish well? My previous prints with the 0.4 nozzle came out like hot garbage compared to this one lol!

Adjacent lines on the layer aren’t touching. Should be a single, solid layer.

Generally, if you stop a print at the end of the first layer, it should be solid and strong.

That one looks like it would it would come off in many pieces

depending on the slicer you are using, you can make a cube and set the height of the cube to whatever you have your first layer height set to. Then print that. While it is printing watch it close and baby step down until the lines are pushing together making a nice flat surface. That is what I usually do after a nozzle change and I want to get it back set right. That was suggested to me by the great @Michael_Melancon and has worked great for me every time I have used it

I will take a look at how to do that. Thanks!

is it possible that this could be an e-steps issue? Under extrusion because of e-steps? Thanks!

If it was under-extrusion the top would look the same. Which it looks like in the other piece it does.

That could be esteps, flow, extruder gear tension, bad slicer profile, a worn out nozzle or (less likely) a partial clog.

So I was working nights the last couple of days and so I’m back to this again. I took a look at my prints again and to my eyes, they look closed up and solid. I used a 0.6mm nozzle with 0.32mm layer height. I wonder if my phone made it look worse than it is?? Here is the bottom surface of the stub and nut separated.

Hi! I’m completely new here and didn’t build my LR yet (but I want), so take this with a grain of salt. But I own an ender like 3d printer for a fiew years. Yor origial pics look worring. Hope you managed to resolve main issues but it is hard to tell seeing only bottom layers. My suggestion is to start printing one of the pieses, stop the print after 5-10mm and check what is going on inside your piese. How walls are connected to each other, how straight are the corners, how infill is connected to the walls, is it possible to break printed lines with nails and fingers :grin:
