@pverdin This is Nylon G, right out of it's air tight container and into print.
Not sure why the colour went from white to this nicotine yellow, does it not age well? Either way it printed nice and clean, I leveled the bed and calibrated my Z height and this is the result.
I can't do everything in Nylon G, so need to resolve why PETG failed.
@erikescudero Sorry, I forgot to mention I employ a Printdry system, the filament spent the weekend drying before I started and it remains in the drying with the heat running.
Having moved on from PLA to PETG I must be missing something basic here. My calibration blocks and test looks pretty good.
Thinking I am a roll I go to print a space guy, my final go to:
The half guys are when I stopped the print, the supports are easily picked out and are crumbly. Nozzle temps between 235 - 245. I have great adhesion to the print be at 80 degrees.
Starting to suspect a nozzle failure but it's a relatively new Ruby that has about 2.5KG of NylonG through it.
So I am not sure what the heck I am missing but it's getting really frustrating.
@mpirringer Thanks, I will look on Thingverse and see what I can see, I have put PLA on the back burner for now.
@mpirringer I did do this check and dimples appeared in the water, on either side of the nozzle it seems. Ran out of time and went back to Rhyno.
Still not sure why the cooling is an issue, but will try again soon.
Changed material to Rhyno (black) looked fairly clean, I suspect some moisture but still a cleaner print. Changed the cooling shroud and printed the middle two grey guys, still wrinkle butt but now wrinkle face. The far left guy I printed with both doors of the enclosure open.
On the back side, same old butt issues two different fan shrouds tested and again the far left one printed with doors open.
Not sure what the next step, would like to print with PLA for simple economic reasons.
@mpirringer said in PLA Issues:
@pverdin Try to close the gap - You want to direct all the air right under the nozzle where the filament comes out and no where else
Part of my testing with a different material today will be printing a new shroud, probably from Rhino. Thanks for the response.
@pverdin Looking at the drawing for part 503 the shroud, it appears to be solid with openings at either end, mine has a gap that goes all around the unit,
@mpirringer The fan is running 100% on the PLA, not sure how much airflow I should have at the print head though or how to measure other than run it and go by feel.
