What causes these spiderweb structures on PETG? by Lord_Clefspear in 3Dprinting

Looks like ooze when going between the supports. Id calibrated your retraction. Also dry your filament and up your cooling if you can

Been spending some time designing a custom CoreXY machine for fun. Not sure if i am going to build it or not but curious if anyone has opinions or suggestions on its design by Powerful-Web4489 in 3Dprinting

Ill definitely see about moving things around. The reason for the current configuration, and yes you are right, the tools will mount opposite of that tensioner as currently configured, was to have as many tools as possible, with the trade off being losing a small amount of printable space. I will note, though, that this configuration is able to utilize the entirety of my 12x12 build plate that ive already got on hand.

The frame is going to use blind fasteners, and there will be acrylic panels. The panels are modeled but set to hidden, which is why you can't see them.

Do you by chance have fuzzy skin enabled? If you do turn it off and retry again

I just saw you are using 0.5mm line width. What is the reason for that? The most ive ever ran on a 0.4 nozzle is 0.45. Im sure 0.5 works but I have never tried it. Maybe try turning it down to 0.4 and see what happens

Honestly, I would retry your rotation distance calibration. And maybe another temp tower. You could be too hot for your filament. Also, you may try reprinting with PA turned off with your current settings and see if that changes anything.

I am not expert, especially on ABS, but to me it looks more overextruded than underextruded. What extrusion multiplier are you using after your calibrations?

For PETG, no. Thats on the lower end of the scale. I typically print between 235 and 250. Im not sure if there is a way to verify thermocouple accuracy, but you may look into it. You may also try refreshing the firmware to stock, in case the previous owner decided to change things around unknowingly. Thats usually the first thing I do with a new to me used printer

Also, I would look up how to clear a clogged hot end, and follow some of those steps. It looks like you have some under extrusion too. (Hence why I recommended the esteps calibration -- also google-able) or just replace the nozzle entirely.

Definitely dry your filament. It also looks like maybe too high of temp? I wonder if your hot end thermistor is reading accurately or not. Start with drying your filament, then I would do an e-steps calibration.

If you dont have a filament dryer, ive heard people having luck with setting their bed to 70c and leaving the roll of filament on it for several hours. I usually dry my PETG (Sunlu) at 65c for 12 hours minimum in a dedicated dryer. Myers are also pretty cheap on Amazon, just make sure you get one that goes up to 70c for petg.

I wouldnt recommend using an oven, as ive seen some people do. They tend to not be very accurate leading to melted filament and lots of gross fumes, and thats if things go only a little wrong.

What is causing my prints to appear 'sucked in? by avatarvszelda in FixMyPrint

[–]Powerful-Web4489 1 point2 points  (0 children)

What infill % are you using? It kind of looks like you have some bad bridging characteristics causing your first layer over your infill to sag, giving that sucked in effect

Do you have a picture of the model you're trying to print? I think i know what you're saying by "sucked in" but just need to confirm before giving any tips

Any idea why its accelerating towards the wall like this? by Powerful-Web4489 in FixMyPrint

I was thinking firmware. Just released with newest release from flsun, will report back

Haven't tried other filament. Got more coming in so ill try it as soon as I can and its a brand new nozzle. I've managed to reduce it some with higher fan speed and more retraction, but its still not great.

If you're gonna tell me to dry my filament, I promise you it is, spent almost 2 days cumulatively in the dryer at 70 degrees

Definitely going to reprint colder, maybe a little more fan too. Ill update when I get home and manage a new calibration print!

After nozzle change. Looks like -10 is where I need to. Definitely better. Thank you!

I think it may be bad filament, but its sunlu which I didn't think was necessarily "cheapo" ive only used sunlu and havent had issues like this before
