My end of walls have buldges. Each layers have it. And after 14-20 layers, they are stacking so much what it can knock the part out.
It’s a P1P with 3 walls enclosure (i can vent the top)
I’m using Duramic PLA+ (marble)
I’ve calibrated the speed, PA and flow ratio 2X
I’ve tried to override:
Length of retraction (1.5 and 3 mm).
Z hop retraction (0.4mm)
Retraction speed of 60
Wipe distance (tried 5 and 10 mm)
I’ve even tried the arachne for wall generator. All preaty much the same.
My filament is dry bone (in box for over 24 hours. Humidity barely registeres).
I’ve change the CHT tip and i’ve even applied platic repelant!
I realy don’t know what else to do.
The walls are smooth as a baby butt! Only the ends (and seam) are awfull
I wanted to test speed (since it was the only thing left) and to exagerate, i’ve printed with a max vol speed of 0.5
The part is perfect!
So could it be my driving belt that are slacking?
Or the extruder acting strange under speed?
Whats weird is on max vol speed calibration, i can go up to 38.
But when there’s a sharp turn (like a thin wall) buldges forms.
The max i can print is around 2-3 mm2/s!
I can’t conceive this to be normal?
PA was calibrated 2x.
It realy seem to be related to speed but printing at 2-3 mm2/s is slowww. I’ve done this part last year and i don’t think i was printing at that speed (and the part came-out A1).
The max volume speed that P1S can do is about 23 mm^3/s. This number is from CNC kitchen. That was for plain PLA, I think. For marble PLA it should be slower. Say, 19 mm^3/s is a good number.
Not sure I understand it correctly, is it you’ve done it twice or over twenty times? Anyhow what is the value you choose?
I choose 0.040 for the generic PETG I am using while default is 0.020
