Edit: Thanks to everyone for the help! Just an update.
Thanks to @nate3d and @IMALlama comments below I calibrated the e-steps that were very under and it improved a lot.
I left the filament on the dryer for 8 hours and tested again with a 20mm /s speed and 220 C print temp and it was better (picture below)
Just to answer you all saying it’s a clog or a hot end problem, it’s not, the whole hot end, includong nozzle, heat block and everything else, even the PTFE tube are all brand new and I checked before.
This is still the best I could achieve and It took 3 hours to print this benchy lol
‐-------- Hi everyone, I’m once again asking for your help lol Since I’ve tried to print with wood I totally wrecked my printer so I changed the hot end and am trying to set it all up again. Since my printer already came built and working I don’t have much experience with things like this so if you could help me I would be very thankful
What do I need to twerk to make it print better again?
I’m using Cura slicer and trying to print a benchy with the settings below:
Nozzle: 0.4
Layer: 0.2
Printing temp: 220 (it wont print with lower temp)
Speed: 60
Retraction distance: 7
Retraction speed: 70
Edit: PLA
I see you just printed a bonchee.
I’m definitely not a printing expert but it looks like you’re under extruding, is the extruder the same size as the old one or is there some other change like that? I say this because the bottom layers look better than the higher ones, from memory cura over extrudes for the first few layers to help with bed adhesion.
Try calibrating your E steps if you haven’t already. Hope this helps! https://3dprinterly.com/how-to-calibrate-your-extruder-e-steps-flow-rate/
Changed the hot end? Like just the brass nozzle tip? Or the what?
Either way if pla isn’t printing below 220 I’d start with a pid autotune. This will let you see if the hot end is actually doing what it should.
This site:
https://teachingtechyt.github.io/calibration.html
Has all the steps for tuning a printer, pid and e steps are listed. It’s worked well for me on my old Ender3 Bowden drives and many of my newer direct drive ones.
What printer do you have?
Was the hot end pre-assembled or did you assemble it? I suspect you have a mechanical issue, but it might just be e-steps.
Suggestions:
Pull the nozzle off, measure say 110 mm of filament upstream of your extruder motor, make a line or attach a piece of tape, extruder 100mm, and see how close to 100mm you are. No nozzle means you can do this cold so you’ve eliminated 2 variables: a nozzle clog and temp. More detailed instructions
Once you get that sorted, do a PID tune and run the 100mm extrusion test again with your nozzle attached at say 230. Different number? My money would be on a partial nozzle clog.
Finally, temp tower. Not being able to extrude below 220 seems very weird. How fast are you trying to print?
