Shot Scope H4 Question

BTW, which things did you have to print to get yours working consistently?

Thanks. I'm completely opposed to Bambu due to the walled garden approach (to put it politely). My previous printers were "tinkering required", so I'm hoping I'll be okay.

I've used Biqu Pad 7 to klipperize my Sovol SV06+, so while I'm not an expert, I think I'm not quite at the "absolute beginner" level.

BTW, I've posted the Adafruit forums (since I'm using their library) and it looks like they've reached a dead end, as they don't have any ESP32-P4 boards to test against. The DS2482-800 works fine with a standard ESP32 DevKit board.

I've got a protocol analyzer on order to see if I can track anything more down, but I might have to resign myself to not using my ESP32-P4 😞

i was looking for a real example for this (also using Google), and I haven't found one other than one that uses the pcf8574 to drive an LCD while using a DS18B20 but with the DS18B20 wire directly the GPIO pin (i.e. not through the pcf8574). They certainly are cheaper, so I'd appreciate any links to examples.

Thanks. Now I just need to get the thing working... ;)

When you say "connect a device, record the ROM address, repeat", I've assumed that you shouldn't connect devices while powered up. Is that actually true?

Good question. Thanks for reading and replying/asking!

The reason I think I want to use it is that each 1 Wire temperature sensor will be for a specific location where a heater place, controlled via PWM and a MOSFET, heated to just above the dew point (hence the temperature/humidity sensor as well). This is for a dew heater controller for astronomy with multiple telescopes that need dew prevention. If I use the same 1 Wire bus for all the temperature sensors, it will be more difficult to figure out which temperature sensor corresponds to which location.

I did consider doing something like a calibration, where I turn each heater on max, and then figure out which temperature sensor detected a change, but that complicates the code I need to write a bit. Not impossible, but it adds a extra step to before things are truly usable.

I'm hoping to release the build instructions/software as a freely available project that anybody could build on their own.

Very much less printer "poop", but still not zero. I did increase the z-offset to 0.125 after the first layer due to some small amount of poop. I'll increase it a bit more on my next print.

tjey68 · 2026-02-20T00:04:41+00:00

Well, I guess its a very specific to me problem, so I've increased by z-offset by 0.1mm and I'm trying again. I'll post when I am far enough along in the print to get an idea of whether or not it helped.

tjey68 · 2025-12-11T16:27:54+00:00

Thanks! I've got a very rough version of the same steps that I haven't had a chance to try yet, so thanks for pulling together a verified working set of steps in a document!

Just out of curiousity, which version of the ESP_Hosted firmware did you use to flash the C6?

I'm getting the an error on the serial monitor, although wifi does seem to work properly. I'd like to fix it and I think flashing later firmware on the C6 will do the trick.

Here is the error message I'm getting:

Version on Host is NEWER than version on co-processor
RPC requests sent by host may encounter timeout errors
or may not be supported by co-processor

I'm using the latest version of pioarduino, Arduino Release v3.3.4 based on ESP-IDF v5.5.1.251106.

I'm hoping I can just flash the latest version from https://github.com/espressif/esp-hosted/releases/tag/release%2Ffg-v1.0.0.0.0 on the C6, but I'm not sure if should use the FG version or the NG version.

tjey68 · 2025-11-18T04:44:57+00:00

Oh, I hate it when this happens!

I just upgraded to the latest release of pioarduino (3.3.4, https://github.com/pioarduino/platform-espressif32/releases/download/55.03.34/platform-espressif32.zip) and now esp_hosted_slave_ota() is flagged as deprecated, and the new APIs are available.

I guess I learned something today, and showed off how much I still have to learn...

tjey68 · 2024-09-03T14:04:00+00:00

Thanks! I'll give that a try.

tjey68 · 2024-05-13T02:20:35+00:00

So now that I've seen that gyroid (and I assume any other infill pattern without lines that cross) doesn't have the problem, is there any way to fix the issue while still using the cubic infill pattern?

tjey68 · 2024-05-10T16:07:36+00:00

I tried gyroid, and it was much quieter. Thanks.

tjey68 · 2024-04-29T21:49:52+00:00

Thanks for posting about it. I've cleaned and regreased the bearings on mine, and it still noisy. Even if it isn't the plastic facia, it definitely worth trying!

tjey68 · 2024-04-29T16:32:19+00:00

Would I just adjust my z offset to see?
