@mpirringer : I am a bit confued by that. When I look at the heat blocks on matterhackers, they do not seem to designate a filament size. The one I looked at was designed for the e3D v6, which as far as I can tell seems to be the same one that the titan aero uses. Am I looking at the wrong thing?

Also, the aero does not use a heat sink, so I don’t see that as an issue.

@mpirringer ok, I see now that the nozzle is sold for the filament size, so I understand that, but as far as I can see, the heater block is the same for both 1.75 and 2.85. So, that would mean I could get by with ~$30 for the heat break and the nozzle rather than ~$108 for a new titan aero. Am I off the mark?

@erikescudero said in Converting from 2.85 to 1.75 on the titan aero:

There is no easy way to convert the hotend from one diameter to another.
You would need to replace the heat break, nozzle and heater block.
It would probably be better to grab the different diameter hotend.

Curious.... why would I need to change the heat block and tip? I figured I would probably want to change the tip, but I was under the impression that the the heat block and tip I have would work with a new heat break. Wrong?

I have a 2.85mm 24v titan aero and would now like to convert it to 1.75mm. Is there a way to do this aside from just buying a new titan aero?

I bought a E3d v6 24v 3mm hotend and am having an issue with the PLA sticking in the hot end. I start a test print (20mm cube) and the first 2 layers print fine but then the extruded starts clicking and I find that the PLA is in a death grip inside the hot end. The only way I can get it out is to crank up the temp to 240c with the cooling fan off. And the pry it out slowly with players. This has happened twice during testing.

Anyone have an idea what might be causing this. I got the E3d v6 because it is claimed to be the best, but I am having issues with it that I never had with my old non metal jhead.

I will try this, but first I found another issue to be resolved. The PIE is lifting in several places, so I need to redo that. I noticed that when I laid down the PEI, there were some air bubbles that I couldn't get out, so that has to be resolved first. I may go back to the old glass and hairspray which has worked for me for years.

I just finshed a new coreXY build and ran some test cubes (20mm cube). I was very impressed with the results. I tried a larger print, but had to change filament before I did (MH PLA 3mm). I started the print and all looked well until I realized that one part of the print had delaminated. This is the first time I've seen delamination with PLA. I stopped the print and found that If I touch any layer with my fingernail, it delaminates with virtually no pressure. The layers don't seem to be bonded at all.

I went back and did the fingernail check on the 20mm cubes and they are solid. The only difference is the new spool of PLA.

The particulars are
3mm PLA white (matter hackers)
extruder temp 185c
bed temp 60c
0.4mm tip
0.3mm layer height
No fan engauged

I am kinda at a loss to figure out what happened. Any suggestions?

I recently received my Titan Aero. The thermistor connector is something I am not familiar with. Can anyone give me a part number or digikey model skew number so I can order the matching connectors?
