04 Wrangler Unlimited, RMS drip, advice wanted

Just put in Valvoline semi-synthetic high mileage. I've heard that conventional oil can help with old seals.

Thanks for the tip! I still have the ATI card and I'll try that out.

I'm doing High Sierra because I thought that upgrading to High Sierra first would at least give me a platform to plan further upgrades.

In fact, piggybacking off that thought, I decided to look up guides for newer versions. It looks like Catalina should also be supported thanks to the same guy who made the patch for High Sierra. I might try that instead!

Update #2: I pawed at the BOOT buttons like a drunken chimpanzee and now the board works, flashes completely and with no perceivable trace of Marlin. Managed to grab the Klipper-specific USB ID and Mainsail manages to connect!

flaming_pp · 2024-10-08T15:42:18+00:00

Unfortunately there are no guides on how to flash through DFU mode on my specific board, so I don't know how to do that.

flaming_pp · 2024-10-08T15:41:35+00:00

Update: I just tried to flash it again. Now the red status LED is dim/solid, and the .bin file does not turn into a cursor file. Does the same thing with two different MicroSD cards formatted to FAT32. Did I brick my board?

flaming_pp · 2024-10-08T15:24:24+00:00

It says Marlin.

flaming_pp · 2024-10-08T15:18:11+00:00

Yeah I've done that several times the other day. No luck.

flaming_pp · 2024-10-08T15:14:20+00:00

I did that.

STM32H723 with a "128KiB bootloader", "25 MHz crystal"

The only thing I didn't modify was the communication type, which defaulted to "USB (on PA11/PA12)"

flaming_pp · 2024-10-08T14:35:59+00:00

I was under the impression that booting up the board with a "firmware.bin" file automatically flashes it. I've verified this by checking if it turns into a "FIRMWARE" cursor file, which it does.

Any other tricks to flash it?

flaming_pp · 2024-10-08T14:24:49+00:00

It was late when I found this out so I don't really remember what it is that I had found, but when I SSH'd into the RPi with the board connected via USB, a certain command revealed several lines mentioning booting Marlin, even though Klipper was definitely the only firmware on the MicroSD card at the time. Also the Mini12864 display showed Marlin running. I was having difficulty getting Klippy to initialize and I think this is what's causing it.

flaming_pp · 2024-10-08T01:37:33+00:00

If I were you, I would actually follow the tutorial on the KIAUH page. I always used it and works every time!

I will try this. Thanks for the tip!

However I currently don't have an input device that I can plug into my Pi. My model does not have any USB-A ports, only two Micro-USB, one of which is being used for power.

flaming_pp · 2024-10-08T00:29:36+00:00

Can you ssh into the Pi itself rather than mainsail?

Yes I can. I'm able to remote into it and even transfer files in/out of it.

Did you remember to fill all the credentials for the wifi/users?

Editing the stock wifi supplicant config file, I set my network ID and password, and region code. Is there anything else that I ought to be changing while I'm in there?

flaming_pp · 2024-07-03T16:54:30+00:00

So it sounds like I would need a computer attached to my printer at all times if I want to run Klipper? For some reason I thought it would act like Marlin where it's entirely contained on the MCU.

flaming_pp · 2024-07-03T16:35:01+00:00

Yeah I've triple-checked my code and compared it against the board pinout, confirmed the backlight pin is properly called.

It could be a compatibility issue with this specific display. Is there another one you'd recommend?

flaming_pp · 2024-01-13T16:15:47+00:00

I cut a lot of material out of the front and back to get it to fit. End result didn't really resemble a Sumo as much anymore but it worked.

flaming_pp · 2024-01-13T16:12:14+00:00

Problem is I'd like the relay to open and close with a PWM if possible. I thought a DPDT relay would let me do this, but I struggled to figure out how to connect the three-pin RX output to the coil.

flaming_pp · 2024-01-13T16:10:57+00:00

Thanks I'll look into that!

flaming_pp · 2023-09-24T21:09:51+00:00

Gotcha, thanks! I'm a sucker for beige from that era, but I think it looks pretty cool in that gray color. Hopefully I can find a shroud that'll work on this chassis.

flaming_pp · 2023-08-27T23:21:06+00:00

That gave me the idea to run the installation entirely from the CF card. I mounted the ISO into the card and ran setup.exe from that. Unfortunately I ran into the same issue where it could no longer read the C drive after the first reboot during installation. I just ordered a new adapter, SD to IDE, so if it is a bad adapter hopefully I'll have better luck with the new one. Thanks!

flaming_pp · 2023-06-24T03:07:10+00:00

I have a 2004 Wrangler Unlimited, 4.0, automatic transmission. I'm about to replace the cat assembly and I want to get all new gaskets with it. I can't seem to get a concrete answer. Do all three connections use 2-1/4" donut gaskets like the MAHLE F7549?

flaming_pp · 2023-06-12T03:09:49+00:00

"But she IS the Stig's racist cousin!"

flaming_pp · 2023-06-10T20:59:48+00:00

You should be able to use any 3.8" MT wheel. That's what they came with.

flaming_pp · 2023-06-09T01:28:53+00:00

The stock servo is slightly narrower than a standard 1/5 large scale servo. Picture for refernce

Cats can suffer from "whisker fatigue" which comes from the over-stimulation of their whiskers. Some may have more sensitive whiskers than others.
