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

I see you just printed a bonchee.

The fact it won’t print below 220° makes me think it’s a problem with your hotend, and my best guess is that your nozzle is clogged. The higher temperature might be helping the extruder to squeeze a bit of filament around the clog, but not enough.

Changing the nozzle is quick and easy, and most printers come with a spare or two, so I would give that a shot before diving to deep into diagnostics.

  They might just try a cold pull or two before changing the nozzle. (Depening on the printer. On my Ender 3 Nozzle swaps were a no brainer - 2 minutew, on my current SV08 they are 15 min of work and 45 min of soaking the old nozzle in Isopropanol to get the thermistor out without ripping the cables)

    Wow I just looked it up and that is the worst design I’ve ever seen. That’s a ton of work just to replace one of the most commonly changed parts.

My guesses are clog (99% of all extrusion problems), heater problem, wrong filament diameter or broken extruder (check for slipping and cracked arm, spring etc).

I don’t know if twerking helps, but it doesn’t hurt to try.

  As long as you don’t twerk against the actual printer your should be fiiiiiiine.

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?

That looks like a clog.

Try heating up the end, then removing the filament, then cut the filament flush and push it into the end, lower the temp a bit, and yank it out. Do that a few times to try and clear the clog. You can also heat the end, remove the nozzle, and clean it.

While it’s off, try pushing through some fresh filament by hand.

You were printing with wood, so it probably has wood particles stuck in it.

What kind of printer is it?

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.

  it is the same but I could try to change the flow

Make sure all of the parts of your hotend are tightened. Especially where the Teflon tube ends. I set up a new printer once and it was having similar issues and it ended up the nozzle wasn’t fully tightened and was getting plugged up in the small gap. Changed the nozzle, cleaned the plugged material out, and made sure everything was tight, and it started printing just fine. Most PLA should print well at 200.

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:

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?

  oh thanks!!! I’m looking at the e steps and will look at pid after!

Try calibrating your E steps if you haven’t already. Hope this helps! 3dprinterly.com/how-to-calibrate-your-extruder-e-…

  Hey thanks!! This tip was gold and it helped A LOT

I had similar printing issues with some filaments, due to heat creep. The printing would start ok on mine, but after the printer had been running awhile it would print like that. In my case heat was travelling up the hot end and Bowden tube, which was causing printing issues after a certain amount of time had passed.

There are a lot of things that can contribute to that, I ended up replacing my hot end and Bowden tube, and lowered my print temperature some.

220° is pretty high, I would try to figure out why it won’t print below that temperature and see what you can do to bring that down.

  I’m using high quality filament. The low quality ones wouldn’t even print lol

    It really sounds like you have a major problem with the printer that needs to be resolved. Without knowing any more details I would suggest making sure the nozzle isn’t clogged and possibly replacing the hot end.

    What kind of printer is it? Do you maybe have a direct drive extruder while using Bowden style retraction settings?
