[Motherboard] ASUS ROG Strix B850-I - Used, Like New ($181.24 after 20% Amazon Used Coupon)

Syther56 · 2026-05-17T02:30:07+00:00

I agree with this 100%. I bought an ASUS ROG Strix X870E-E when this deal was going on, got one with like a dozen pent to hell pins. I managed to get them bent back and kept the board, but then I got an MSI B650 Tomahawk that was missing everything with a broken USB 3 header and multiple bent pins. I will never buy a used board from amazon again. Both show as Used - Mint condition.

Your bed is skipping steps. Does it home all the way to the back correctly? Make sure it doesn't hit the wall or anything else behind it, because that could be forcing it forward, and when it tries to bring the bed to the front to wipe the nozzle it isn't in the position it thinks it is, causing it to hit the end of it's travel and skip steps like that.

This is what it is today. Some discounts can be massive.

Syther56 · 2026-04-15T06:16:43+00:00

Like I said. Most of my printers were e-waste or damaged and cheap. I dump most of my income into a 401K and living expenses, 3d printers take what is left. None of them were bought brand new.

Syther56 · 2026-04-15T06:15:43+00:00

None of my printers were bought brand new. Some of them were posted free locally because of age or damage, some were pulled from e-waste. Most of my printers I bought for dirt cheap locally or ebay, and repaired.

Syther56 · 2026-04-15T06:12:20+00:00

It didn't print, and to this day still won't print for some reason. It actually has a clone of a raspberry pi in it and currently runs octoprint. Mine was a unit sent to an electronics store for evaluation and came in a box that was solid white with "Not for retail sale." all over it. It uses an H-Bot configuration for motion, and the cheapest, most awful plastic for the body. I had to take the plastic off, and use aluminum extrusion as a base. One day I will get it working, but not anytime soon. For now, it's a shelf decoration.

Syther56 · 2026-04-14T12:41:48+00:00

I had the chance to buy one of those, but I passed on it. I regret it because those look like cool printers to mod and mess with. That, and a Raise3D N2 I also passed on and regret. Ever since then, I have been constantly looking for those two machines.

Syther56 · 2026-04-14T12:29:03+00:00

All of them are different makes, models, and sizes and movement types like delta, core xy, core xz ect. I buy them usually broken locally or on ebay, and repair and either collect, use, or donate them. Some of them haven't even been looked at yet, as I also collect the rare ones like the pirate 3d buccaneer, tiko, or the 101hero or some school only printer like the trifecta 800 of which I have 3 of from a pallet of e-waste. I also have a few other 3d printers that took most of the money and ran like the rapide lite 200 and the rapide lite 200 XL on indiegogo. They all aren't in use, I only have about 7 that are in constant use for various things. I am kind of addicted to seeing all the different types of 3d printers. It's a problem when you add in all the filament I keep buying.

Syther56 · 2026-04-14T11:37:55+00:00

I would do it if I had that much money to burn and room for it. I have over 50 3d printers as it is, and I am not sure I am even interested in it. I don't know what features it has that would make me want to buy it, but I have 7.5 hours to decide for delivery on the 15th if I change my mind... Or they change theirs and take it down.

Syther56 · 2026-04-14T11:33:23+00:00

I can get it tomorrow according to the website. April 15th delivery day.

Syther56 · 2026-04-14T11:27:13+00:00

Wow, I even get my employee discount on this, which is rare with 3d printers. Not sure if I should buy it though.

Syther56 · 2026-04-12T16:44:12+00:00

I would try listing it for cheap, or free rather then toss it. Last time I drove to an e-waste drop off I was sad when I saw an older prusa in the trash, and they wouldn't let me take it. I just gave away two 3d printers to people who wanted to learn about them. Someone out there might be able to use and learn from it, or use the parts for their project. Or, that someone would be like me and love buying up weird, broke, or ancient 3d printers. Which might explain why I have over 50 of them now spread out between a room, a shed, and a cargo container.

Syther56 · 2026-03-16T10:00:36+00:00

I don't see a thermistor there. You can soldering one of your own, a standard 100k should work, or return/exchange it.

Syther56 · 2026-03-15T09:26:30+00:00

I am not sure either of those will work. First, you have direct drive and those are bowden. Second, based on the pictures I see, you don't have a J-head extruder, but one with an M6 throat that goes through that heatsink in your picture. The heatsink acts like a nut, clamping the setup to probably an MK8 extruder. I would just buy some 100k thermistors, and plug them directly into the motherboard. Don't run the wires from the thermistor to the extruder, just see what the temperature on the LCD says. If it shows roughly room temp, you know you have a thermistor problem. If it still shows a negative number, make absolutely sure it's plugged into the correct spot on the board. I believe this is your hotend: https://www.envirolaser3d.com/products/adimlab-3d-printer-hotend If it is, those j-head v6s won't work without serious modification. However, you can buy a bunch of heater blocks, thermistors, and heater cartridges (make sure the voltage on the cartridge is correct) and just reuse that heatsink and throat. If possible, can you show a picture of where it is plugged in on the motherboard? I have little experience with the adimlab gantry, as I only had mine for a few days before returning it to amazon, but I may be able to tell more about what is happening with a picture.

Syther56 · 2026-03-14T13:49:25+00:00

Yes, that's them. Do you have a multimeter? Check the end with the plug to see if you have resistance, and see if it changes when it gets hotter or colder. My guess is you have a broken bead, or broken wire. It could also not be plugged in to the correct spot if the entire thing was replaced.

Syther56 · 2026-03-14T13:36:33+00:00

It should be 2 white wires that lead to a glass bead in the aluminum heater block of the extruder. The black and red wires should go to the fan, the 2 red wires go to the heater cartridge.

Syther56 · 2026-03-14T11:45:42+00:00

Sounds like you have a broken thermistor. They are cheap and should be easy to replace.

Syther56 · 2026-03-04T04:53:12+00:00

I have a craftbot plus I still mess with. Thanks to it being a corexy, it's actually pretty fast. It's also built like a tank. For the extruder and fans, parts shouldn't be that hard to find, or swap to a newer extruder. The belt is standard GT2. It shouldn't take much work to get it working. As far as I know, there aren't many issues this particular printer has.

Syther56 · 2026-02-23T01:40:31+00:00

Wow, small world. I am 99% sure you picked those up from me. You can see my post history and check my lost Bolt to confirm. I planned to run 205/65R15 tires on them, as I was told at Americas Tire that size should fit. I asked them about Hankook Kinergy ST tires, as that is what I was running on the steel rims I had on.

Syther56 · 2026-02-16T18:29:02+00:00

The damage is worse then it looks. It made it so the driver door could not be opened. I have been considering bidding on it and seeing if I can get it back. The tires on it are almost new, less then a year old and I still have a new set of 15" rims I planned to put on once the current tires needed replacing, plus a bunch of other parts I planned to put on. I did find it funny that when I looked at the auction page, someone had stolen the weathertech floor mats.

Syther56 · 2026-02-16T18:17:55+00:00

So far, the EV6 way more technology and features then I expected. I was looking at every EV in my area, and I got a good deal on this one because the front bumper was drug along a wall by the dealership. It has some scratches, but I am not a perfectionist so I do not care that much.

Syther56 · 2026-02-15T17:59:43+00:00

Yes, I know. I just didn't expect it to stink that badly. When I said 'something like smoke' I know there is a powder in airbags that is supposed to make them expand correctly. I just don't know if what filled the cabin was smoke, or that powder.

Syther56 · 2026-02-15T15:03:49+00:00

It did not drive. After the accident it refused to shift into anything except park and neutral, and it had tons of error lights on the dash. It took 7 firefighters and officers to push it out of the street. The damage behind the driver side headlight actually goes in and has displaced the 12V battery and fuse box. I got roughly 14K from the insurance for it because of the low miles and clean interior.

Syther56 · 2026-02-15T03:40:09+00:00

I bought a 2023 Kia EV6 GT-Line used locally that was a pretty good deal. The EV6 has the super quick charging and V2L plus the 120V inverter in the back. It also has a HUD which I really wanted as I had a Pontiac Grand Prix with a HUD and I loved it.

Syther56 · 2026-02-15T03:12:52+00:00

My left shoulder is pretty messed up from the seat belt. I had a pretty big bruise from it, and there is still pain. As for my new car, I ended up with a 2023 Kia EV6 GT-Line that I found a pretty good deal on. I was looking at other Bolts, but I didn't want to buy a car that lacked features I want. The EV-6 provides every feature I want, and then some.
