Hi everyone, and thank you in advance for your help!
I hope that I started this topic in the correct area, if not please let me know! As you can see in the below photo, the printer (Ender 3) works more or less correctly, but I’m facing with an issue every time I print and I try to add letters. It always leaves some space without cover of the PLA filament.
What I tried: Changing temperature of the PLA / PLA material / Changing wall configuration / Slicer, etc
First of all thanks for your reply. I’ll try your suggestion during this weekend. I have not seen that option before, so thanks a lot. Once I do a print I’ll by able to tell you if your suggestion worked!
I did the suggested changes, but as you can see in the picture, still having the same issue… Do you think if there is any other possible options / issues?
I ran you .stl file through Cura and found this.
The settings of line width of 0.4 show small lines in middle of the letters. When I changed it to 0.5 the lessened. Sometimes the font you use can cause problems. I have found hat Arial Narrow works well with 3D printing.
Give it a shot. See attatched.
The percentages is the extrusion factor as I’ve found it to cause blobbing in the past, but not for this model. Temperature is 230C, Bed is 80C, speed is 50mm/s, retraction 0.5mm and pressure advance 0.1325.
You might want to look at changing your retraction value as there may be a problem here. You can also vary your extrusion factor to see if that helps any.
If you are using Cura, I would suggest to try the “ironing” option for the top most layer. If you printer setting is dial-in correctly, this would help to close any gap at the top.
Sorry for the long time without writing, but I was very busy and I didn’t managed to had the time to experiment. Now, had the time to test it and I think with the Ironing part it solved the main problem!
The only thing is that now the lines seems to be very visible and other minor issues, but this was a great advance!
