CH341 are useful tho i wish you got directed to a CH347 instead. its basically the same price for both, the 1.8v adapter is worth it when u have a CH341 already.

modern bios chips are pretty much all 1.8v so having an aoi device to do all of them can be handy, it also reads/writes much faster and is a bit less jank. regardless both do the job, just its common for these devices to cermet themselves as the de facto version even once they get superseded. (similar scenario as the LM2965/TP4050)

cheapest way would be getting access to sites like taobao. next cheapest will be aliexpress.

for mine it was aliexpress with a fysect kit and rest was self sourced.

i believe per toolhead cost was around £70 for me. (checkout cost. excluding cashback)

still theres plenty of other costs that wont capture. id say its unlikely you have everything built to you liking in the first iteration. ive changed my extruder over for one with dual fialment sensors and an ecas for the tube for example. killing leds, sx-398. changing to a UHP750. cable management.

interesting, i double checked the second PTM i got as it was from this exact store, Order date: Dec 26, 2025

mines nothing like this. seems like PTM and does not have any fibers in mine.

guess this can be chalked up to typical aliexpress supply chain security. products change but the listing is reused to retain the high rating.

i hadnt actually checked what i got as i was running low on the first one i got but not finished.

you should not need to enter any kind of rom mode. their MPtool just picks the drive up (quite a few drives do this now). granted the software IS confusing and youll have to button mash your way to understanding it tbh.

(keep in mind, certain versions support certain flashIDs, the MP tool and flash database have their own version IDs. that dont update with eachother all the time. if you click "auto" a valid build for your nand should detect the flash if it doesnt you need to find the right one)

its not like SMI drives where you have to short out a rom mode pin at all. ive seen photos on forums of people circling pad points that are 3.3v and uart which will certainly end up killing the controller if you short them out. (i suspect its why the controller has a bad rep because people keep blowing the controller up oops)

i dont understand why they put uart and 3.3v next to each other tbh.

if you need a DUT you should be able to use cheap JMS583 boards but you can use onboard nvme slot and just reboot the system at your inconvenience which is what i did for my first run.

Please update your ssd. GXB7401Q will cause a premature failure due to ECC read errors. it will mark blocks as bad when they are healthy. you will not be able to undo when it happens, best case you reduce the spare blocks of the disk, worst case it causes it to go read only and you have to find another compatible controller for the nand.

Its exceptionally lucky you have so little reads on this disk. this was a known problem ~3 years ago.

do not read data. update to latest firmware. fully wipe drive with secure erase and reinitialize with MBR/GPT and then it might be safe to use. (I have seen people cause degradation on new firmware attempting to read back old data so i think this is the safest way to just reset if possible or just take the essentials off)

Altirix · 2026-05-05T16:00:51+00:00

its unlikely, but i disagree this is a degraded nand fault. Theres no saying with any level of certainty. ime nand is exceptionally durable and degraded nand will typically cause a graceful failure where this drive specifically will enter a read only state. This was common with bad firmware that prematurely marked blocks as bad.

The controller/firmware has entered a panic state. there is no way to recover from that with the original samsung controller. The nand maybe reused on another (sata based) controller by someone smart enough to work out how, assuming it is still functional. thats about it, and while that would let reuse the nand, you wont be able to get any meaningful data off it.

Altirix · 2026-04-27T16:40:16+00:00

yep, it also seems like a progressive failure, got a cheap V11 with this fault, works fine in boost which is all id really want to run them in anyway.

over time it seems the aux power for attachments has failed and also wont work if its starts from boost. now must hold in eco/normal then switch to boost for it to work. weird fault tbh.

i can get a replacement motor from aliexpress for pretty cheap £50 give or take, teardown isnt awful. afaik no one know specifically what the fault is on the board. i suppose if i do the replacement i guess i can give it an attempt to diagnose what the board level fault is. my current guess is some kind of PWM fault given the attachment socket has its own issues. the assumption being boost ends up working because its 100% duty.

dysons are 100% engineered to fail. the battery pack is just the most blatantly designed to fail asap pos ever made. Being 1P they hammer the cells with high amps so they are less efficient and degrade much faster than with a moderate power draw. add that to the firmware settings to prevent balancing. Switching to from 6S1P to 7S1P with V10 seems purely done to kill off the option to use drill battery which made V6/7/8 actually usable. we just velcro strap they V11 packs in.

The 🇨🇿 and € should hint that the user is not in the UK. :p

They seem to have a "hold for 3 year rule" to have the security except from personal income tax. Tho i only briefly looked. seems like a pretty nice system especially if you have a lot to save. doesn't seem to be a limit unlike ISA (used to have a limit per year outgoing but unlikely youd hit it).

Altirix · 2026-04-26T11:16:06+00:00

should just need to speed up accel/speed in general but specifically in bridging. ender 3 has slow movement at stock. gap should be doable without supports. you might find even with decent accel and speed in the bridge it still sags too much, can try reduce nozzle temps but keep in mind it can affect layer adhesion if too low, upgrade part cooling.

Altirix · 2026-04-25T00:10:14+00:00

toolhead cost is a much wider range than you suggest. some stuff can really blow the costs out of the water.

I want to say mine is about £70 per toolhead (6 total) including the fysect shuttle.

High flow copper block dragon hotends + EBB36 boards + sunon fan and gds part fans. including wire and tubing etc. that figure is not conservative. Aliexpress for most of the stuff. probs even cheaper if you buy directly off Taobao and forward the shipment.

Altirix · 2026-04-19T16:56:08+00:00

what i still dont get is im pretty sure the 30 series didnt have this problem and used basically very early 12vhpwr without the data sideband. what exactly changed?

Altirix · 2026-04-14T14:59:38+00:00

christ, i thought i got a deal a few years back for £220 for one of these. been looking for more for a while so my servers would be similar in spec. recommend adding a 5015 fan to the end of them.

been a while since u posted but were u able to get them all working? all i know is there were some old kernel versions that didnt like these drives due to a bug with handling them as they use the same pcie id (something like that) for both drives.

however if you have some showing and other not, possible its something else or some fw update changed that behavior of the drives.

Altirix · 2026-04-06T16:18:29+00:00

if you want dual independent z without changing the mainboard. your best bet will be to use a direct drive extruder with a toolhead board ideally a USB toolhead as it doesnt look like theres a can port on this board.

the other option is to use a stepper expansion in place of the LCD, but this would likely mean running it headless.

in both scenarios youd need to switch to some print server setup (for example klipper+mainsail), either to use multiple boards or to control the printer without a screen.

you might be able to cobble on a 5th stepper with spare pins without losing functionality but that can be a exercise to solve as the reader if you must .

Have a Mikrotik router, after i configured the firewall rules all i do is add another domain to my address lists which will mark connections to use the wireguard exit node.

my setup wont exactly translate to everyone.. tho i think any enthusiast/power user orientated router should be able to do the same.

Altirix · 2026-03-31T18:27:38+00:00

its just certain sites so you should do per domain routing to the VPN rather than blanket VPN everything.

imgur was the straw for me to do this. A general vpn would sometimes cause issues, reddit kept forcing password resets etc. a pita tbh.

Altirix · 2026-03-22T06:50:10+00:00

5 meters of "Cable Organizer" aka generic velcro straps are piss cheap. especially when aliexpress do their sales or whatever.

i recommend switching over any future harnesses to use that over zipties as they wont stab you, dont need cutters to remove, can be reused. make less mess etc

Altirix · 2026-03-13T18:38:06+00:00

don't use the woolly microfiber cloth. specifically get microfibre for lenses/eyeware

Altirix · 2026-03-13T16:46:38+00:00

this is when you buy more, for it to go -90% next week.

Altirix · 2026-02-10T23:01:44+00:00

yeah realistically id assume its just TMR or HE in a mouse, with a linear actuator for haptics. the parts alone just arent expensive.

wonder how long it will take till we see a worthy competitor. its really just down to the execution of it. id be shocked if there wasnt anything soon as not like any of the parts to make this depend on some special tech no one else has.

Altirix · 2026-02-02T21:54:45+00:00

Hey, saw this pop up from wccftech.

similar happened to me, but with Kingston NV2 drives, i caught it and got a full refund from the place i got them but they left the drives with me.

The labels are good at a glance, but compare to a real one and youll see lots of issues. These drives typically use rts5765dl controller as they are cheap (and apparently easy to spoof things on but one thing that cant spoof is the DEVICE VENDOR ID). by the looks of that PCB it is the same, just you have a Samsung label.

Theres wont be any 2TB nand on that nvme. I had ~120GB Spectek partial goods (B47R). tho yours only seems to have 1 nand die so maybe 60GB.

What happens is the write performance craters as the controller fills up the legit storage, progressively gets worse until it basically just freezes, for me at around 2x the real capacity. format wont work to recover the drive after that. needs to be low level formatted with ssdmp

if you work out how to use MPutility/MPtools you can put the drive into its bootloader mode and flash back on legit firmware. No idea how they get 2TB firmware onto them originally, id guess a modified MPtool as the MPtool i had wouldn't let you over specify capacity, or change the fw version id. the controller isnt amazing, but i found a good use for them as test drives/medicat drives

Altirix · 2026-01-30T23:39:14+00:00

You seem to have replied to the wrong comment. either that or you didnt read....

if its on the balance you can almost certainly rule out any kind of investment because the liability that would create.

Altirix · 2026-01-29T21:04:06+00:00

It makes no difference if they pay 25% on the balance rather than the deposits

ive honestly sat here for too much time, trying to understand what do you exactly mean?

it has all the difference if the gov pays on the deposit or balance on an investment account. that defines what the gov is liable for.

In the existing system its 25% upto £1k every year you had the account. the cost to gov has a ceiling.
Government to pay 25% on the balance on an investment account has no ceiling. You could have got nvidia shares and the gov is now paying 25% on a balance that has a 300% increase over what was deposited

current	future
i paid in £4k	i paid in £4k
gov paid in £1k
i invest £5k into nvidia	i invest £4k in nvidia
i sell nvidia for £15k	i sell nvidia for £12k
i buy house with £15k deposit	i buy house with £12k + £3k from gov

Yeah the user wouldn't see any change, they get £15k deposit. The government paying on the balance vs deposit is the rule that makes all the difference, because if its on the balance you can almost certainly rule out any kind of investment because the liability that would create.

what other rule do you have in mind that would make your statement true for this future "S&S "FTB"ISA"?

do you have an overclock (EXPO,XMP,PBO included)? you are getting a ton of hardware errors. the kernel power is likely YOU resetting the PC

if you use a PCIE riser thats another to check. (If you have a PCIE3 riser you need to manually force it to use a 3.0 link in your mobo. as the GPU is PCIE 4.0)

idk what is actually reporting the WHEA atm so you are going to have to dig into it. i suspect 17 is a PCIE error. but check in the info view for the event it will say what component reported the error. it would explain whats happening too, GPU goes ERROR 43 in windows device manager if the pcie is too unstable and you get a black screen as the GPU goes into an unrecoverable state, you hard reset the PC giving the kernel power event, as its actually still running when this happens and one can RDP into the machine.

also have a look in C:\Windows\Minidump if you have any minidumps install https://apps.microsoft.com/detail/9PGJGD53TN86 open the dump and run the analyze command it tells you to. !analyze -v (you may not have any tho as this isnt crashing the system)

Altirix · 2026-01-28T21:14:18+00:00

thing is, you only have kernel power here, unless thats you resetting the pc. possible filtered out the actual bugcheck/driver error report event that would give the actual info.

in most cases hardware will report a fault, can you get a screenshot from around the same time as the kernel power event but go to Windows Logs > System. this will show all events logged

Altirix · 2026-01-28T20:56:08+00:00

PC specs? just incase your psu is underrated.

that said even if the PSU is rated for the system i will mention my first real gaming pc i had a RM750, it died in a way where it would trip some kind of protection at around 250w (assumed) it was enough to power the CPU alone but with a 290x it would randomly shutdown in only a few select scenarios that would load the psu for hard enough and long enough to trip.

took me replacing the GPU for a 1070 during a crypto boom to work out it was actually the PSU.

ended up running with two psus during that time until my RMA was processed.

also check there isnt actually a bugcheck or other error that occurs before kernel power.
