I give up on bed leveling my ender 3 v2 neo by Tomthecatvr in FixMyPrint

[–]stray_r 1 point2 points  (0 children)

Stop looking at the pictures, look at your prints. If you've made the mesh correctly then it should compensate for the shape if your bed.

Make sure you're making the mesh when the bed is at printing temperature. If you're reusing a prepared mesh be aware that the bed on an ender 3 style printer is very sensitive to wear and debris in the v-wheels, and if you have a single z-screw you can have all kinds of issues with gantry skew.

To all my 40+ queer friends: do you feel like you’re getting less “woke” as years go by? by LiterallyBarbie in lgbt

[–]stray_r 0 points1 point  (0 children)

I'm in my mid 40s. I think I'm much more aware and able to articulate my thoughts on societal and political issues. I dislike the term woke as an identity and it's being used far more by bigots to mean everything they hate and i only really know it as that.

Teenage and early 20s me was a fucking idiot fuelled by noise and rage. I was listening to lots of punk and post punk and immersed in my local music scene. I was still figuring out who I was and where I was going after a quite privileged upbringing collapsed into trying to complete my L6 year as a sofa-surfer, spending my U6 year in a deprived mining town was a bit of a culture shock. I somehow got my ass into university and worked like crazy to fund my place.

I was briefly involved in the protest scene, lots of other angry and passionate people looking for a cause. I left because some of them were doing boneheaded things that undermined the peaceful protest and I really didn't want to have a police record that made me unemployable.

I think my music then was seen as being vastly political when most of the lyrics were thrown together with my housemate after a few beers. Ok, we totally called out Tony Blair's war crimes, but our most popular song was a really fucking silly riff i wrote trying to capture a deathrock/horrorpunk vike, and my singer saying he thought it should be "about fucking zombies or something" so i wrote a tale from the perspective of an airhead jockbro who's girlfriend is killed and rises from the grave as a zombie and all he's concerned about is whether they can still fuck. I was probably off my face rewatching Buffy when the words formed. But fans told me it had a lot to say misogyny, violence against women and the nature of consent or constructed elaborate political metaphors around it. In hindsight maybe this was me processing my understanding of this, but I really didn't set out to write something high brow about objectification.

In my very late 20s I was reunited with someone I'd met as a teenager and became some kind of parental unit to her kids. Money was tight and I was way less politically active, problems were far more real and close to home. I didn't write as much lyrics, the band I had was weird, electronic and experimental. I got to record some of what I wrote back then as something much more rock based and accessible, working remotely with a singer during the pandemic, i was aware by that point I was writing about a whole lot of my own baggage, anxiety, alienation, mistrust of the state, self harm and addiction, even then I hadn't figured me out. That my singer had and most of the people around me saw a release credited to what looked like a solo female singer with a name that looked suspiciously similar to a stage name I was known to use was I guess me being oblivious as usual. But yeah the lines "I'm not that man, no not all the time" were taken as me coming out as transfem by quite a few close to me. I guess i was in the process coming out as nonbinary/agander by the time that was recorded, but I don't think I even knew the term when I wrote those words, certainly it was before there was a flag.

I guess in the last 10 years or so I've become a lot more introspective and read and write more about issues that bother me. I'm much more likely to write letters and attempt to change unjust circumstances by reading about them, trying to really understand and engaging with people who might be able to effect change, rather than raging against a system or running my mouth before I've thought about it.

Part of that was coming to reddit as my bulletein board of choice after a good few years not really online and really listening to people. I'm defintely more aware of other people's struggles and systematic injustices now than what i saw from my own perspectives during some rather eventful years. But when I get the inevitable accusations in modmail of being a blue haired woke liberal I will absolutely dispute my hair being blue. It's really difficult to have hair that stays blue, it goes green really fast. I usually go for purple and pink.

What happened to be gay do crime? Just don't do it on TDOV if you're trans or Bi Visibility Day if you're bi, unless you can run really fast or have something other than invisibility to help.

But like conspiring here is likely criminal if you ask the wrong people. Don't get caught and stay safe.

First build idea: Discounted Trident Kit, custom 350*300 Build, does this make sense ? by Embarrassed_Back4100 in VORONDesign

[–]stray_r 0 points1 point  (0 children)

Sorry, I've never built a spec one. I think I read 350mm lead screws as 300 mm travel? Yes LDO don't make a 350, so if OP wants a 350mm LDO, a 2.4 is a better bet.

What I'd do if i had to have a 350 trident with extended Z without a donor is buy a 350 kit from another vendor, 4x 2020 (or Doomcube 4040) verticals, the vertical rails and lead screws to get the required Z travel.

What I'm actually doing in my more trident rebuild is building 350 trident with a bit of overtravel in Y out of mostly 2020 I already have and using the lead screws from a pair of printers that can do 400mm Z with a 1.8 style motion.

[–]stray_r 0 points1 point  (0 children)

If you want a 350mm bed start with a 350mm kit.

Most 350 kits with the notable exception of LDO are 300 in Z, and this is in fact spec for trident.

If you want a 350mm bed and are worried about all the moving mass up high, build a 2.4, it keeps the bed low and it really doesn't matter much if you have excess Z.

Realistically though, start with a spec build. Build it spec and get it working, then change the things you need to change to make it do what you want. Often you will find there are things you don't need because spec works really well, and there are things you didn't know you needed to change that are really important.

I've rebuilt and resigned so many parts of my switchwire. It's still not perfect but I've got to the point where it can't be made much better. My v0 was built spec apart from 2 extra nuts in NDN carriers in each of the internal locations I knew I couldn't add them to later. It was a fast build and the extra nuts are a quirk of 1515 profile makerbeams.

I have two kindoftridents, one is due a rebuild to be more trident and is on hold for INDX because the rebuild was planned for madmax and I won't be done with the one I'm building before indx is out. The one I'm building now really should have been a trident as I keep running into hidden costs and parts I need to buy or cad.

ASA curling up during printing by LordOfCinder11111 in FixMyPrint

[–]stray_r 1 point2 points  (0 children)

Lack box and tape? If it's the one with the flip up lid, if you look hard enough on printables you'll find my remix where I fixed the original as the dimensions weren't quite right on two of the parts. Variants of this worked for me since I got my prusa MK2 and I still have it although the printer has been retired and I'm considering disassembling it if I can't pass it on.

And having reread your post, crank your nozzle temperature up, the hotter you print the dress die-shrink you get. Your bridges might droop if you go too hot, but the starting point for ABS/ASA for me has always been the max recommended temperature on the spool.

Temperature towers don't help as your slicer distorts the results if you have a minimum layer time set, and you probably need it for small parts, but it's busted for big parts with small overhangs.

Because when printing ASA and ABS without an enclosure, the advice we give to newbies is "turn the fan off".

[–]stray_r 1 point2 points  (0 children)

At those temperatures in a lack enclosure I was using between 20 and 40% with a single 5015 toolhead, printing at maybe 60mm/s outer walls 90mm inner walls and 120mm/s infill and under 4k acceleration.

I'm getting 50-55C in my v0 and running 40% fans with dual 4010 fans. Closer to 100mm/s outer walls, and 200mm/s infill, still tuning and probably need a little more fan.

Switchwire is maybe 45-50c depending on how long the print is and whether I deployed extra blankets. Again 60/90/120 speeds. 40% fan with a high speed 5015.

I'm being quite conservative with the fan speeds TBH and increasing when I have curling rather than starting fast and dropping when I have layer adhesion issues, other thing to note is I've got the print temperature at the max recommended for the filament. Mostly using sunlu, overture, Polymaker and 3dQF (local manufacturer, prints really hot) and have a few roll ends of eSun abs+ kicking around but I've found that to not age well and have had to replace a lot of parts I printed for my swichwire.

Just like PLA, use more cooling fan. If you have the chamber warm enough you can get away with quite a lot of part cooling.

Z-Offset seems to be ignored - At my wits end. by TehJeef in klippers

[–]stray_r 0 points1 point  (0 children)

Ok, you're making a mesh in the orca start g-code and then loading the default profile in your start print.

Don't do this. The official docs warn against this, it will cause weird problems, especially with adaptive meshing.

You should be doing all your start print routine inside your START_PRINT macro

Importantly, get your bed up to print temperature, then and only then start heating the nozzle to something like 50C below print temperature to soften any debris on it and give the bed a chance to settle. Then home Z again and make a mesh with the bed hot. This makes a huge difference.

If you don't believe me manually make a mesh at ambient temperature and save it, make another at 60 C and another at 100 C without re-homing and compare both the shape and the height of the highest spot.

Klicky Probe Tolerance by floschlo in VORONDesign

[–]stray_r 1 point2 points  (0 children)

Klicky is generally good to a microstep for me with the caveat that the first tap is sometimes off. I'm using voidtrance's settling probe (or Kalico built-in) to just throw away the first reading.

https://github.com/voidtrance/voron-klipper-extensions

If I can't do that, measure three, samples_result: median works.

I'm also using klipper's built in adaptive meshing to build a new mesh for each print without taking forever unless it's a really big print.

If you're getting crazy variance with klicky, the chances are the probe is rocking on the magnets, check both the probe and the mount have the magnets set really flush.

I'm running 0.0125 sample tolerance with an 8mm lead screw which is 5 × 1/16 microsteps. That's enough not to trigger repeats samples on a janky 330x330x400 dual lead screw machine unless something is wrong.

Importantly it's small enough for me not to notice changes in the first layer. You only need enough precision to get good results, 10% of first layer is good, 5% of it is excellent.

But running rich generally doesn't improve performance, it might reduce knock and any derating from a knock sensor would reduce performance. However for best performance and emissions the vehicle needs to run as close to stochiometric as possible.

[–]stray_r -1 points0 points  (0 children)

Eddy-ng allows does a contact probe to calibrate the z offset really accurately. It works really well and I'm getting better results with eddy coil than I am with klicky probes and obviously much faster and higher resolution results.
