Anyone have any tips for printing E3D edge filament?
If I print at 240°C it looks too hot and melted. If I print at 230°C the layers don’t bond.
Have you printed a temperature tower? I use one of these to gauge the optimum temp and other settings (extrusion multiplier, speed, retraction etc.) to get the best for a particular filament and my printer. Also, have you calibrated the extruder for the filament so you know that extruding 100mm actually extrudes 100mm?
FWIW I really like this one to test new filaments. It is a pretty tough test and is easy to customise for temperature start/stop and precision:
Copolyesters are very glossy so that might be part of what makes them seem melted. I agree on checking extrusion flow rate and extruder calibration. The material might have a larger OD, you might have too high of an infill overlap.
Not really what I was hoping for!!

@Daniel_Wood Something seriously looks up with your extrusion. It’s hard to tell if it is over or under (my guess is over) extrusion but if I were you I’d be going through these settings in your slicer, and calibrating the extruder. Check the diameter of the filament carefully in several places with callipers too and update your slicer accordingly - even a deviation like 1.73 vs 1.75 can make a difference when the slicer is calculating the extrusion amount.
Also (probably a dumb question) but is your nozzle diameter set correctly?
@Alan_Lord I’m going to start working through all the settings.
No such thing as a dumb question but the nozzle is set correct.
The filament is really consistent between 1.74mm and 1.76mm.
I’m going to work through some bridge torture tests and see if i can improve the settings.
Thanks for helping!!

@Daniel_Wood The layer lines are very pronounced. What layer height are you printing at? I’ve not used this kind of filament before so don’t know what it is supposed to look like but that looks to me like there is way too much filament being extruded…
To give you an idea - this was how mine looked when I was testing some PETG:

Layer height is 0.2mm. I think the zoom looses perspective and black seems to make everything look worse.
I decided to try simplify3D. This prints the bridges much better.

I normally use Slic3r PE. I have tried Cura a few times and don’t get on with at all. I use IdeaMaker occasionally as it is more forgiving on bad meshes in STLs than Slic3r.
Another thing to check is how dry is your filament. Your are supposed to keep edge fairly dry to maintain printablity and strength

OK that looks great, what was your solution?
I just tried simplify3D. I had a feeling it was slic3r causing some issues, just need to figure out what it was now.
Hi Dan, if possible can you tell me/us the following. I apologize if you have already answered some of these as I have not read every comment.
Media type ABS?
Filament Diameter
Nozzle Size
Temp.
Feed rate.
Fan Speeds
Bed Temp.
Retraction rate if using.
How old is the media and has it been in a dehumidified environment.
@Alan_Lord thanks for the advice, burnt both thermometers on my printer, what ones are most durable in your opinion?
Filament: 1.75mm Edge very black
Nozzle: 0.4mm
Temps: 235°C / 60°C
Feed rate: 60mm/s
Fan speed: up to 100%
Retraction: 2mm @ 40mm/s
Extruder: E3D titan aero
Filament is 1 week old.
@JC_Ouellet Not sure I understand?
@JC_Ouellet all thermistors are pretty delicate. If you can machine metal, you could modify your parts for but E3D’s cartridge thermistors. They seem decently built.
