Gunk when changing filament

Gunk when changing filament

I am having issues with gunk when I change filament rolls. I've got a Flashforge AD5M and to do multicolor, I insert pauses in the slicer and change the roll. Previous color and new color poop.

For some reason, huge piece of gunk always forms. Same seems to be true with first layer. Notice some with PLA, but really apparent with TPU. Roll is dried properly in a dryer and mount above to feed direct into extruder

Most of my prints ok, except for like a letter or so in this example.

Is there a gcode command to extrude out a line right after pause? It always does that at very beginning of prints. Thank you!

System of a down hat WIP

Making a SOAD hat! Got some good advice earlier about lyrics. Got all 10 patches i could find and still have lots of space to fill surprisingly. Looks a little nasty pinned on loose but better with more pins. It's 18" circumference so you can see it laid out in a line the best. Overlap with irregular patches over rectangle seemed to work well. (1st Pic).

Would appreciate any SOAD ideas. 3D printed some song names and lyrics. Thinking of 3d printing some bullets to go next to "beliefs, they're the bullets of the wicked". Maybe just metal studs? Some guitar picks?

Battle hat advice?

So I already made a battlevest and am putting together a battlehat. Had surgery on my leg and can't really do much else these days. Got 10 patches for System of a Down and a bunch a bunch of button pins (1 for each album). A bit busy and cramming rectangles on a curved surface just doesn't look clean. See first 4 pictures.

Second arrangement, I cut back to just 5 patches. I like it better. See pictures 5-8

Would appreciate any advice. Battle hats are kinda rare and now I see why haha. Weird background, used plastic viking helmet as a stand.

Advice and/or printer profile for TPU on AD5M

I have had a lot of success printing pla and petg using built in profiles but have struggled with TPU. I have a dryer and it doesn't seem to help. Any advice on how to calibrate or settings you've changed? Thanks!

Lyrics/words for the bill of a DIY SOAD hat?

I am big into battlevests and system of a down and thought why not make a SOAD Battle hat? Got some sick patches and what not but was thinking of 3d printing some song lyrics for the bill.  I want to be able to wear this out so unfortunately no FUCK THE SYSTEM, although that's the perfect length.  Some ideas;

1.  REVOLUTION, THE ONLY SOLUTION

2.  BELIEFS, THEY'RE THE BULLETS OF THE WICKED

3.  WHY DON'T PRESIDENTS FIGHT THE WAR?

4.  LIES FROM THE TABLECLOTH

5.  HOW DO YOU OWN DISORDER?

Any others? 2 and 3 are kinda long. Maybe just all the band members first names?

Zion worth it if you can't hike?

Unfortunately ruptured my Achilles so I probably won't be able to hike come my trip the end of September. Was going with just my wife, our last such trip was 3 years ago. Between babysitter, flights and hotel I'm out hundreds of dollars if I cancel everything. But I'd spend even more of course if I go. Might be able to bike. I know there is ATV tours, horseback riding, kayaking. Anyone have much experience with zion or utah and not hiking? Had also planned on going to Bryce. Was really looking forward to angels landing and narrows but I think those are off the table.

Flight is 9/18 12pm arrival Las Vegas, Wednesday 9/23 8am departure. I can get a travel credit for canceling (can't change). 4 full days doesn't seem like much time for zion and brcye. Maybe just scrap the whole thing and try again next year? Maybe then I'll actually get the lodge. Is spring a good time to go?

How to preserve autographs: embroidery?

Im so pumped, got 10 autographs on my 3 biggest patches. I may want to wash this vest someday. I'd like to preserve these somehow. I've heard people say embroider but have any of you actually done that?

I could take off the BFW and LR patches, embroder and sew back on. My back patch though has a double sided iron on. I kinda miss sewing my vest and am out of patches, so perhaps just take my time and go slow? Is there like a shiny silver or metallic thread?

Meeting Mental Cruelty and Larcenia Roe

Got to meet some of my favorite bands!  Saw last show of Shadow of Intent/Angelmaker/Mental Cruelty/Synestia tour in Detroit.  Drove 6 hours across 4 states to get there.  First time seeing Synestia live and they were INSANE.  Took a friend who had never been to a metal concert and he loved it.  Afterwards, met vocalist Ryan Vale.  Talked a bunch about Synestia and also Larcenia Roe. The LR drummer Morgan Simmoms was there too!  Got my ridiculously oversized Larcenia Roe patch signed by them. 

Also met  Mental Cruelty again, my battlevest backpatch band. Got it signed and a  picture with the band!  Super nice guys, they headlined my first real deathcore concert years ago and they spent a while talking to me then too.  The chance to meet these guys to sign my backpatch was a major reason I drove so far and so glad I did.

Special thank you to Angelmaker merch guy for the silver maker for signatures, wish I could have met those guys again (super cool too, did their VIP last year).  Wouldn't have got those six autographs that night otherwise. I now have my 3 biggest patches signed!

Was in the pit for a bit and did my first crowd surf.  Pretty sore now and my voice is shot, but this was the best show I'd been to.  Oh yeah, and the music was phenomenal too.

AD5M: Best setup for a dryer when printing TPU?

I have done a lot of PLA and only thing I have done to maintain dryness for that is ziploc bags with silica packets.

Right out of the package, TPU was OK but seems like practically speaking I'll need a dryer. Second print a few days later was a disaster.

I sometimes do prints with 4 colors (pause layer and swap roll). My thought was was get a 4 roll dryer. Can it just sit on my desk and go through PTFE tube for PLA? I printed an adapter for TPU and leave lid off, can I also set a big 4 roll dryer next to the printer and have a long loose run of tpu go to printer

Anyone do sew on 3d printed patches? I've seen 3d printed stamps on fabric. Didn't have much luck with the stamping method. First 2 pics are 0.2mm thick background layer, machine sewn 1st then hand sewn. Rest are pins (superglued on pin hardware).

I think the pins will hold up and I can take them off to wash. Thin PLA material to make patches will probably break down. Maybe I'll try flexible TPU, just harder to use with my printer.

For my patches/pins pictures, Google image search PNG

->Gemini for logo simplification (not needed for all) ->Inkscape to make DXF cad file

->Fusion 3D for cleanup, making layers, STL file

->Flash Forge AD5M (requires manual pauses and filament changes)

Had a few inches of settling over irrigation lines, so at least we'll be able to water new grass easily . Hard to take a picture of but very noticeable if you look or step on it. This is all sos we had out in last year. Options:

  1. Topdress. Dump 50:50 mixture of soil and sand and level with rake. Leave a little high. Seed.

  2. Dirt under sod. Cut out 1'x1' chunks of sod. Place on a tarp. Fill cut out spot with soil sand mixture. Replace sod. A little dirt top dress too

  3. Something else?

Never tackled something like this. 200 ft of trench if I had to guess. 1 seems a lot easier then 2 but will it leave a giant line of dirt diagonally across my yard all year? Thanks!
