Terrible surface finish
This is the first time I run into this issue, I haven't changed any settings prior to this happening it seems the lines are squishing too close together
Layer height of .2 line width of .350 with a .4 nozzle using cura.
any thoughts ?
Could it be that your z-axis failed to step up in the last layer, or the gcode has an issue causing the same? The surface of the euro symbol looks perfect, it's only the top layer that's got an issue. Could you attach the gcode file for this so I can inspect it?
In general, you'll get the best results if your extrusion width is the same size as your nozzle diameter or up to 20% bigger. So in your case I would recommend setting your extrusion width to 0.4mm.
Also, enable 0.2mm of Z-hop (aka retraction vertical lift) to avoid lines like this when the nozzle does a travel move over the top skin -
It might also be a hardware issue - do you have a removable magnetic build plate? Perhaps some dirt got between the plate and the base? Or maybe the bed shifted slightly out of alignment when you put force on it to remove a print? Can you also grab the nozzle (when cold) and try and jiggle it and see if it's loose? In that case you might need to check all the bolts of the frame and carriage for tightness, as well as the nozzle itself.
Looking forward to your reply 🙂
I have checked all of the hardware parts and they all seem to be functioning correctly, I'm going to re-level the bed and try some of those settings and see how that goes thank you!
