Infilll and Solid Infill and Max speeds for 0.2 print profile (stock) is way too high for certain filaments #16

Hi there! I wanted to report an issue relating with the Infill/Solid Infill and Max speeds for the stock 0.2 print normal profile. For some odd reason, they're set REALLY high (80 for the infills and 90 for the max speed to be extact) while every other profile is set between 50-71. For certain filaments (PETG in my case) this is way too fast for the infill to handle and it will immediately get ripped off the model and make basically large gashes in the model (which inventibly causes print failures).

Currently, I've set those settings all to 56 and that seemed to have fix my troubles. I haven't tried out the high speed on PLA but it's definitely way too much for PETG to handle

Ok, one more check: with steppers enabled (Holding) try to pull fillament by hand to see if gear rotate, it shall not rotate. If filament gets out mean gear grub is lose. NOTE: You must do that with filament not glued in hotend, so pre-heat hotend to 215ºc

I can't get it to budge at all

Well i'm out of possibilities, i guess you have to decrease speed for PET go with it. As last check, go slicer and see if nozzle size is correctly set, as extrusions width on advanced (should be 0.45mm)

Welp! I just I may have discovered what our culprit is! So the weather in my area has been going nuts lately (with it being abnormally hot and because it's Louisiana, the humidity is quite high) and my main air conditioning unit breaking due to the extreme heat, the humidity in the air must have gotten high enough to actually affect the prints. So I went today and let my window air unit run for the majority of the day. I just ran the print and the layers came out much better than before (with a few minor artifacts, but overall much nicer finishes) all at the stock profile settings

Humidity ruin pet spools, if you have that issue better build a spools dehumidifier. Or cook it at 50°c for day

Ok I think my PETG doesn't like the new temp settings, mid way in printing out this case, I notice this MASSIVE clump of filament stuck on the nozzle and it literally jacked the entire print up

NovaViper commented 5 years ago

The lifting at the very bottom right was from me trying to remove the part off the bed after I canceled the print

@Zviki68

What's your nozzle temperature? And what slicer you are using?

240 and Prusa Slicer, I'm using all of the stock filament profile settings that's for the Generic PETG filament

Hey im going to close this! I switched to a TriangleLabs V6 and my printer's being doing really well with the infills and PETG! Thanks for making the profile!

sn4k3 commented 4 years ago

Most likely a extruder problem before.

NovaViper commented 4 years ago

@sn4k3 The oddest thing is that im actually still using the stock extruder, and the printer prints perfectly now with PETG, haven't experienced the same issue since switching

sn4k3 commented 4 years ago

Some bad tune, better this way
