ESUN ePAHT-CF bridging issues
I'm able to print just fine but bridging is a pain with eSUN ePAHT-CF.
Even overhangs are fine without any fan at all but this bridge in the photo below was printed with 25% fan, it didn't help much at all.
I'm using a 0.5 TC nozzle, filament is properly dried for days @70°C and then three hours @90°C right before printing.
I tried 30mm/s bridging speed, 60mm/s bridging speed (the filament profile is limited to 10mm³ anyway) but nothing helps.
Even though it's just a single 5015 fan for cooling, I don't feel comfortable ramping it up to 50% for a PA-CF filament, although that is what I'm going to do now.

I looked at @MFBS profile and he's using 25% fan all the time. CPAP is probably way way more powerful than mine
So ramping fan up may be a solution? Or going down in temperature? Currently printing at 270°C with as mentioned 10mm³ limit
Chamber temperature is probably something 30-40°C
50% fan permanently seems to help bridging and causes warping :hiding:
50% permanent fan
Well....
Will try to set bridge flow to 0.8 instead.
I don't use 25% fan all the time with ePAHT....that would decrease interlayer adhesion. I use the minimum fan necessary. Bringing and overhangs with any nylons is always challenging.
I will post up my fan settings later when I am near my computer.
Thanks for helping me out. There are just a handful of people out there who print it
I has bridge flow set to 1 and probably 0.8 as set in your SS profile will also help. More fan doesn't.
I use Orca Slicer these days. Thick riding helps sometimes and other times causes more issues. I have never found great bridging options.
This is my first and probably last roll of eSUN ePAHT-CF. I also bought a couple of Siraya PPA-CF. Does it have similar bridging issues?
Look at that. 100mm/s and 0.8 bridge flow
That is almost perfect 🙂
25% permanently. Remember, single 5015
Do you have thick bridgeing on?
Yes
