earlier this week i showed off as a proof of a RTL8127ATF working on a mac using a driver made from a git. But it was just a proof of concept. Finally a all in one solution came in, and works like a charm as well on macs.

This is a USB4/Thunderbolt based adapter and shows up under the system as a thunderbolt pcie bridge. then a realtek chip connected to that.

Side note for anyone whos uses macs, those running MacOS 27+, they ship with its own realtek driver. So plugs n play on those.

Here is the link

These PSUs can be found cheaply and are rated highly for BC250 community. its a platinum rated.

On a previous post ive seen people open them up to get a 5v rail that inside of them. But i wanted to use one without having to modify it.

Made a small board that connects the 2x5P connector to a solderable 24pin power connector. it Provides the PG pins along with a small DC-DC that powers the 5v rail needed.

This power supply also perfect for SFF because the cables are just long enough to reach were they need to without too much left over.

Not sure if it's just me but has anyone had something similar to this issue? Let me explain, after doing a filament change, the extruder starts to click on long linear travel.

It's petg but happens on asa and pla as well.

I know everyone will say the filament is not dry but I'm sure it is.

Ive even tested the following: unload the current filament, cut the tip and re inserted the same filament. (So it wil.be the same consistency removing the variable of a new roll). And it starts clicking. Tested by faking the loading sensor to thinking the filament is unloaded and have it load it again. No matter what it starts clicking when resuming a print.

I then cancel a print and restart it and it prints just fine. No matter what part of the print, when I initiate a fillament change it starts clicking. But restarting a print always fixed it.

I also changed the nozzle. Same issue. Did a cold pull, same issue.

No matter what just restarting a print fixes it.

Does anyone know if their a bug in the latest firmware?

Hello!

i posted a working prototype a lil while back but was able to almost complete the whole thing. Been trying to get as small as i can but use a semi ok graphics card. Using a lenovo m90q gen2 board with a 11500 (non T), a custom Riser i made, and some cad work to make a sheet metal the base were everything bolts down to. Oh and yes, due to it being a 11500 CPU, it runs on PCIE gen4 speeds while still using cheaper ddr4 ram :)

Internal volume comes down to 191mm X 184mm X 108mm.

The aluminum base was designed by me and sent to SendCutSend to get it cut bent and anodized. ~102USD

Riser was made by JLCPCB. ~29USD

PC lenovo m90q gen2 11500~ 220USD

Additional stick of RAM (32gb total)of DDR4-3200 ~101USD

Lenovo RTX 4060 P/N: 5V11K41546 ~278USD

Lenovo 80+ platinum PSU P/N: 5P51D77273 ~104USD

some screws and PCB standoff , thermal pads~10USD

A couple of cool things. PSU i used is capable of delivering upto 400w in short time and 350 sustained, it provides a 20v power for the tiny PC, and also has the 12v out for the GPU. the enable signal to the PSU to turn on the 12v rail is handled by connecting the green wire to ground. so i added a small mosfet and some resistors to the riser i designed to turn the power when the pc turns on. So the riser, reason i had to make a custom one was to raise the height of the pcie slot. i did not want to use a extender and wire it up in a weird way so this was my best solution. the way i got the Lights to show up to the front of the case is by using flexible fiber optic light pipe.

Overall its small. But too many specific part number parts in the build. Next i might try and make another one to accommodate a bit longer graphic cards, better pick of PSUs and still be able to keep using lenovo 1L pcs but with more variety.

Just another tiny Lenovo with a. Custom build case.

This one is using a 230w external power brick, rtx 2000 ADA, and a 25gig sfp+ card. This has been a. Great little work PC. I did make it a bit tall. But just matches the spec of a 3U height so a lot of dead air inside.

A week ago I took a pic of a project I was starting and just wanted to show a update. Made the base out of 3mm aluminum. Using 6mm standoffs, a custom riser I made with dual pcie slots, and a power supply from a Lenovo neo ultra ( so and a 20v output for the PC and a 12v output for the graphics card). Just have to do some cleaning up in the back Io ports on the model. And will most likely get a second aluminum chassis cut, bent and this time anodized in Black to make the PC look better.

This is a Lenovo q90 gen2, and a i5-11500 (non T) so I am able to run the nvme drives and the graphics card at pcie gen4 speeds. While having the ability to use ddr4 stick so much cheaper. So far this has cost me about 620ish dollars in total.

Showing off a q90 gen2 Lenovo with my custom riser. Got the idea when I saw how the neo ultra are built. Internal power supply with the 4060. Instead of adding nvme drive I just added a x4 slot to stick a 25gig sfp card.

For now it just has dual supplies. The normal one to power the PC and a board I made that dropped down the 20v to 12v from a second Lenovo power supply. Hopefully in the future I'ma see if the single 330w Lenovo supply's can handle the PC and graphics card together.

Will most likely stick this in a 10in rack. But will be a super nice remote gameplay using bazzite.

Showing off a case i made for a 920x. Made a riser that can hold two pcie cards and fits all with a noctua fan under a 2U height. and a 10" jbod enclose that has a custom backplane i made. Right now just testing the drives with a 29mm spacing between them in terms of thermals. but hopefully will have some long term results. has a Flex ATX power supply that gets turned on/off at the moment by the 920x pc automatically.

i wish their was better ways to clean up the use of SFP ports from the front to back of the mini rack..

Super nice to be able to mount my on my deskPi 10" rack in a 2U factor. Needed something with dual PCIe cards so this was a no brainer. (This also works if you have a duel slot single pcie card) If anyones wants to take a look at my project here it is:
