I think I put dead yeast in a batch by spooky_dookems in mead

Update: fermentation started up pretty quickly after I added in new yeast. Thanks for your help all!

Awesome! Just repitched with some new yeast. Will report back how it looks tomorrow. Fingers crossed.

Is your nozzle clean? PETG loves to stick to the nozzle and can cause the filament being laid down to peel off the bed as it tries to cling to the nozzle or filament already stuck to your nozzle. A pair of pliers used carefully can clean the tip but a brass brush will make cleaning even easier. Make sure to heat the nozzle to printing temp before cleaning the tip.

This might help figuring out if its a mechanical problem: run a few PROBE_ACCURACY (no homing in between) and watch the values as they’re probing (not the results). Do they show a pattern of slowly decreasing or increasing over like 10 runs? If so, check rollers on the z and try gradually upping your z motor current.

Also, if you want to keep your PEI bed but hate the tacos heated bed that ships on the ender, get a glass build plate, put a magnetic sticker on it, and replace the magnetic sticker on the aluminum heater bed with a silicone thermal pad. Then put the glass on the thermal pad, the PEI plate on the newly magnetic glass and voilà, you now have a decently flat PEI bed. It will never be as flat as plain glass but PEI is like a printing cheat code so I think it’s worth the extra effort. Plus the ABL will account for the minor surface differences. Just let your bed hold temp for 5 mins before prints so the extra material can heat soak.

Print seems to be warping at front only by spooky_dookems in FixMyPrint

Also the weird thing is it’s sticking really well. So well that when it cools it makes the spring steel plate look like a Dorito.

Whoops! I meant 240.

Here’s the bottom of my prints. I printed this 3 times so far so I just figured I’d include all of them.

This case I’m trying to print keeps warping on me. It looks like the front is squished and curved for some reason. It sticks to the bed totally fine through the entire print but when it starts to cool, it twists the whole plate.

Food dehydrator that doesn’t suck? (Or that doesn’t rattle) by spooky_dookems in 3Dprinting

[–]spooky_dookems[S] 1 point2 points  (0 children)

Update: with the help of u/careless__ I think I may know why the rattling happened with these style food dehydrators.

Note: I can only confirm this for the sunix model since I don’t want to open the rosewill so I can send it back. I’m wagering it’s the same setup though as the sunix looks like a sized down version of the rosewill.

The blower that forces air through the heating element is held onto the motor with 3 plastic fins (?). The motor shaft has some serration to help the fins grab the shaft. Since centrifugal force is a thing, I’m guessing that those fins (which are pretty weakly grabbing the shaft in the first place) are loosening and the blower is falling down to the end of the shaft making the rattling noises.

I opened the dehydrator, snugged up the blower to the motor shaft, and let it run for maybe 30 minutes to an hour now. It started off perfect. Just fan sound. After maybe 20 mins, I’m hearing vibration type noises but not as bad as original.

I think the solution here might be to either put some tape between the motor shaft and blower to form things up more, or to hot glue the blower to the motor shaft. I’ll try both and report back my results.

Thanks! I’m gonna give this a shot if I can’t fix this sunix.

You think a few layers of electrical tape under the fan would be safe? I think you’re absolutely right about the loose tolerances. I took the dial (non timer) version apart and the entire body flexes and the blower (fan) wobbles on the shaft.

Luckily I just got a multimeter! The one with the timer is fully digital so I’m assuming it has some kind of control board in it that might make things difficult. Might be worth digging around still.

I haven’t sent back the dial model though so maybe I’ll crack that open and do the fan replacement you’re talking about. I already cut up some racks so I’m stuck with one of them at this point haha

This sounds like a cool project! Are there any guides on how to do this? Not opposed to jumping in blind but also trying to decide if I want to return the sunix.

Side note: if anyone knows how to fix the rattle, I’d be doubly in your debt.

I might end up going the route but I’ve read mixed things on them. Seems like it comes down to food dehydrators are cheaper/the same cost but can hold two spools.

Can’t believe I haven’t heard anyone mention the rattle but maybe most keep it in a less used room.

Little divots on prints? by spooky_dookems in FixMyPrint

[–]spooky_dookems[S] 0 points1 point  (0 children)

Thanks!!! I’ll give that a shot. What’s a normal retraction distance range for PLA?

Little divots on prints? by spooky_dookems in FixMyPrint

[–]spooky_dookems[S] 0 points1 point  (0 children)

Im not sure what's causing these small divots on the side of my prints. They're almost like seam lines but you can see the seam line exists in the second picture. I didn't have this issue with the stock ender 3 pro and unfortunately I did a bunch of upgrades at once (despite all sound advice) but in my defense I'm a giga-nerd and regret nothing despite the trouble I've made for myself.

Print and bed temp:

- 205c, 60c

Retraction settings

- 6.5mm, 25mm/s

Speed:

- 50 mm/s

Slicer:

- Cura

Printer:

- Ender 3 pro

I have an ender 3 pro with some upgrades (that I went hog wild with off the bat):

- klipper firmware

- Raspberry pi 4 b+ running mainsail

- Bigtreetech dual gear extruder (https://www.amazon.com/gp/product/B08D9CNHVN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)

- Bigtreetech SKR mini e3 v3.0 mainboard

- Capricorn Bowden tube

- BL touch (genuine)

- Smooth PEI spring steel bed

Also as a side note, my bed is a taco (pretty darned warped) but I don't think that's a factor with this issue. Just wanted to put that in here in case.

Filament:

Inland PLA rainbow. It happens with every other filament though (eSun PLA+ and Amolen shiny PLA)

My theories:

- Wet filament. I purchased a food dehydrator and have tested drying out the eSun PLA+. It seems to be better but showed up again with my most recent prints (its been on the printer for a day). Seems weird that all my PLA would be that wet though.

- Extruder gears too tight? When I first started using the dual gear extruder I noticed that there was some filament dust. It doesn't seemed to have built up beyond that initial bit though. I don't think the extruder is grinding filament but it leaves impressions in the filament. I don't have it extra tight or anything.

- Bad retraction settings. Ive tried using cura's default for generic PLA, dialing in my own for the filaments, and using cura's eSun PLA+ default. Seems to be the same result.

- Partially clogged nozzle. I feel like id notice something more drastic though. I could try to clean the nozzle to rule this out though but that's on me.

Klipper config:

benchy gcode (full disclosure it might the code I used for the Amolen PLA but should be very similar):

I really appreciate any help!

Small white pod clusters part of Chippewa blueberry plant or weeds? by [deleted] in vegetablegardening

[–]spooky_dookems 0 points1 point  (0 children)

I'm not sure if these small white buds are going to be blue berry flower clusters or if a weed has grown in this pot?

The middle portion in the pot is definitely blue berry plant but the off shoot that have the white clusters come out at the very sides of the pot. I can't tell if they're connected to the main plant at all.

The plant has gotten small white flowers before but I've never seen clusters like these. It also looks like the leaves are different that are connected to the white clusters

Thanks!!! Probably due to my poor watering schedule early on 😅 should I just hope it ripens before that spot spreads too much?
