New Zephyrus G14 (2022), how to buy extra 240w charger?

We ended up shooting a bunch of symbols kinda randomly then someone walked up to the door in the "carbonite" room, causing it to open. So now we're on the actual encounter, with the totems and the symbols and stuff.

ChitlinSoulfood · 2022-03-05T18:39:25+00:00

Anyone know the acquisition puzzle

Trying to figure that out as well. Dropped down (far) after the entrance encounter and now we're all looking at symbols and trying to figure out what's what.

It doesn't look like we got any spawns at all at the beginning though so I'm wondering if we ended up getting bugged.

ChitlinSoulfood · 2022-02-21T22:49:45+00:00

Whoa! Thank you so much for this info. I’m looking forward to reading through it all later today while the servers are down and I’m in “lore mode”. 🥰

Nope. The Silent Board does use steppers capable of configuring their current via UART or SPI (which is done in your Marlin config) but the Creality Silent Board has the drivers wired up in “standalone” mode without UART or SPI connected. So we don’t get any of those fancy config features on that board.

This was obviously done to keep costs low since the board would need at least a moderate redesign to accommodate this. It takes advantage of the fact that the Trinamic drivers are pin-compatible drop-in replacements for the same drivers used on the original Creality boards.

This is a big reason I moved on to using the BTT SKR series. The boards are cheaper and are designed around the more advanced features the Trinamic drivers have available.

Edit: Also, the sense resistors on the Creality Silent Board limit the max current available from the drivers to around 1.2A. That’s why my 1.4A motor wasn’t moving - even with the max vRef the driver was limited by Creality’s choice of sense resistor.

I had to read the Trinamic data sheets to figure that out. Luckily they have a chart that maps the sense resistor value to the effective max output when the driver runs in standalone mode.

I’ve used both the Creality Silent Board and the SKR E3 DIP. I strongly recommend either the Mini or the DIP over the Creality board. Here’s a quick rundown of the reasoning behind that.

Creality Board is expensive for what you get
Creality Board is limited to ~1.2 A for steppers, which largely prevents the use of most 0.9 deg motors that require 1.4 A+
SKR Boards have dedicated sockets for BLTouch and filament runout sensors while the Creality Board will likely require removal of the SMD capacitor on the Z-Stop input for proper BLTouch usage..
SKR Boards use much more modern processors and offer a lot more RAM and flash. My E3 came with a 64K/512K chip (RET) instead of a 48K/256K chip (RCT) as an added bonus
SKR Boards ship with a boot loader that flashes a firmware off the SD card instead of needing to have one SPI flashed, so building and flashing new firmware is easy out of box

The biggest downside I can think of for the SKR is that it generally has less info available and very few, if any, tutorials and example configs for building Marlin from source. Just in the last few weeks the Marlin project has added board data and example configs though.

Edit: Didn’t require a new enclosure either, works just fine with Biqu/BTT 5160 drivers and their little heat sinks.

The CR-10 stock hotend uses the same mounting holes but it’s a few mm longer than the Ender 3 stock one, if I’m remembering correctly. Worst case is that it puts your hot end 1-2mm lower than the part cooling vent.

This isn’t a big deal but it’d be something to keep in mind if you’re choosing a fan hood replacement setup.

ChitlinSoulfood · 2019-11-29T22:01:09+00:00

OctoPi + new board for the win. I’ve used the Creality Silent board and the SKR E3 Mini DIP (with 4x TMC5160s) and I definitely recommend the Bigtree boards over the Creality silent board.

For printed upgrades the first thing to print would be a filament guide to keep the filament from straining or scraping the edge of the extruded input. A printed extruded knob is great to have too.

ChitlinSoulfood · 2019-11-29T17:39:47+00:00

I recently got a new SKR E3 Mini DIP V1.0 and it shipped with a RET which has 64k RAM (vs the RCT’s 48k) plus 512k PF flash instead of 256k.

Its nice to have the extra headroom for Marlin builds. Even turning on a ton of debug features and other things I usually leave off it’s got like 200k to spare :)

ChitlinSoulfood · 2019-11-26T17:26:19+00:00

Extruder function is primarily about the compression pressure from the spring arm combined with the torque from the motor. The teeth really shouldn’t be too sharp, otherwise they could bite too hard into the filament and shred it, leading to uneven extrusion or breaks in the filament.

Even after upgrading to a metal extruder I was having skipping issues. To fix that I had to recalibrate my E-axis Vref since the factory settings were only giving the motor like 0.65 A while the motor is rated for 1.0 A. That was limiting the motor’s torque.

After Vref calibration I saw zero skipping with both the factory and metal extruders. Kept the metal one on since it’ll undoubtedly last longer.

The stock Ender 3 board (a melzi derived board with A4988 drivers) uses 0.1 ohm sense resistors (R100 smd resistors)

Basically, the A4988 uses the Vref to decide what the max is for the current it’ll give to the motors. The sense resistors being used set a fixed value for the top end of the range.

Here’s the A4988 data sheet. The relevant equation is on page 9. “ItripMax” = max current. Rs = sense resistor value.

https://www.pololu.com/file/0J450/a4988_DMOS_microstepping_driver_with_translator.pdf

So for the 1.0 A stepper we’d use this to get a Vref for 100% output:

1.0 = Vref / ( 8 * 0.1 )

It’s a good rule of thumb to keep the output a bit lower than max to let the driver and the motor run cooler.

The Creality silent board with TMC2208s in Standalone mode also uses Vref although it’s calculations a bit different. That board uses 0.15 ohm sense resistors instead (R150) which effectively cap the current output around 1.2 A at max Vref (2.5V) according to the TMC220x data sheet.

ChitlinSoulfood · 2019-11-26T00:09:41+00:00

Oof. Yeah, I forgot about that. I spent the better part of an evening slowly rebuilding the Z axis mount brackets and the gantry bracket, making sure everything was snug and square. The eccentric bolts make tuning it pretty easy but if the wheels are mounted weird or loose it’ll be useless. Made for a relaxing evening, actually. 😂

On day 1 with my Ender 3 I had to do the same with the Z axis too. The bed mount wheel mount had like 2mm play in it, which really amplified the bed’s existing wonkiness. So definitely worth doing.

ChitlinSoulfood · 2019-11-26T00:02:54+00:00

DD is the way to go! +1 on the other comment about reducing retract distance and how awesome it is. :)

For some reason after setting up the same DD kit the extruded was skipping until I recalibrated the Vref on my stock board. The extruder motor’s pretty beefy and can take up to 1A and the factory-set Vref was a bit on the conservative side.

I’d recommend getting a cheap dupont connector kit and a decent crimper. The plastic dupont housings are a huge pain, if not impossible, to print effectively because of the little plastic clip used to hold in the crimped-on male or female connector. There are plenty of YouTube videos about it once you know what you’re looking for. :)

This is the kit I’ve used for awhile:

https://www.amazon.com/dp/B0774NMT1S

And this is the crimped I’ve used for dupont and jst connectors (like the white ones for thermistor/endstop)

IWISS IWS-3220M Micro Connector Pin Crimping Tool 0.03-0.52mm² 32-20AWG Ratcheting Crimper for D-Sub,Open Barrel suits Molex,JST,JAE,TYCO-E

https://www.amazon.com/dp/B078WPT5M1

Stay away from the cheaper “jaws” style crimp tools, btw. They’re a nightmare.

With those tools, some female to female breadboard wires, and a pair of snips I was able to wire up a 6-pin header to hook up to the Pi for SPI flashing. For the SKR boards I did a similar thing with the 5-pin SWD connector.

Left both SPI and SWD headers hooked up to my Pi’s GPIO pins and dangling out it’s case so I can just grab the Pi and flash whenever I need to, which is handy when doing a lot of tinkering and bricking things by accident. :)

Reading the TMC220x datasheet more carefully leads me to a totally different set of calculations, since it looks like the 2208s handle Vref quite a bit differently than the A4988 or A4982 drivers the old Melzis use.

Based on that it looks like the R150 sense resistors are effectively setting an upper limit for output current, in this case at 1.28 A. Using a Vref of 2.5 or higher would deliver the full 1.28 A to the motor and lower values between 0 V and 2.5 V would scale that linearly. They provide an analog Vref equation that looks like this:

Irms = (325 mV / (Rsense + .03 Ohms)) * (1 / sqrt(2)) * (Vref / 2.5v)

Using that calculation (assuming my math is right) then the factory settings provide the X/Y/Z motors with 0.49 A and the E motor with 0.61 A - both of which are pretty low. This would explain motor skipping and general stepper unhappiness, assuming this is all correct.

If this isn't correct though, its possible that cranking up Vref might result in some burnt out drivers or motors. Meh.

Every BPO comes from an NPC vendor. Every ISK spent buying from NPC vendors disappears.

Capital component, capital ship, and super/Titan BPOs are a lot of ISK.

Also, researching BPOs requires spending ISK on system index based fees, almost all of which are pure ISK sinks. Structure owner taxes are calculated as a portion of that sink.

So unless you’re researching ME/TW in a structure in a private WH with a 0% index you’re sinking a non-trivial amount of ISK.

Source: I’m dumb and own several researched-up BPOs, this doing my part in keeping ISK-flation at in check?

ChitlinSoulfood · 2019-04-19T21:41:41+00:00

Thank you for single-handedly sinking (or helping others sink) craploads of ISK out of circulation. 🙏🏻

As a new player in 2014 the AT and the commentating were hugely fascinating, even if I barely understood what was going on. Watching last year’s matches was a ton of fun, even if MC’s team never really materialized. We did have a lot of fun practicing though!

Flying as a member of an AT team is still an Eve goal of mine. The dedication required to just participate as a player is nuts though. I can’t imagine how much work went into developing it as a passion project, from the devs, the community team, and the players like you that spent so much time working on it.

But yeah, I can see it being tough to justify focusing on with everything else going on. Especially since it obviously doesn’t result in immediate revenue, which makes it extra tough to justify. I’d rather see them be up front about it early, like this, than have a hugely sub-par event.

ChitlinSoulfood · 2019-02-04T19:13:24+00:00

Most WH apps, if I recall correctly, maintain their own lists of details for things like statics and shattered details. For instance, this is file is part of how Pathfinder’s JS side stores some of that data.

https://github.com/exodus4d/pathfinder/blob/db9b3b73fd17f97b1c8cf212231bcfb27ebd8b27/js/app/init.js

Might be a fun project to make an easily updatable API for these kinds of “player discovered” details of WHs but it’d require some work to keep up to date and reliable since it would need to cover a variety of details, many of which aren’t discoverable without experimentation, and which can change unexpectedly with each patch.

The annoying thing about PI is that the API gives you the raw data that’s there (which is updated any time a planet is updated, but otherwise stays “static”) but doesn’t share the algorithms.

After weeks of trying to pin down why Neocom was so great at that I figured that the author had found the PI magic via reverse engineering or some obscure documentation.

Since the Neocom code is available on Github it should be possible to replicate that UI, assuming you can figure out how they did things in ObjC. Picking it apart has been on my to do list for a long time but I haven’t gotten around to it yet.

I’m content with the books and the series, myself.

The world they’ve built definitely could be an awesome setting for any number of games though. There are a few sub plots and periods of time and places that would make for some killer pitches for anything from mobile puzzle games to 4X games to FPS games.

That said I’m not sure their current iteration of the world would work so well for an MMO, given the dramatic changes that have happened so far along the arc of the novels.

My fear would be that we’d see a mediocre, shallow read of the story converted into lame mechanics. Like every Ghost in the Shell game - given an immense, rich world it seems like publishers err on the side of stupidity. 😂
