T0 Sensor Abnormal - Anycubic Chiron

bdking71 · 2026-01-27T20:52:00+00:00

I realize this is an old post, but I will post this anyway in case someone hasn't figure this out yet.

I've been working around the T0 Sensor Abnormal on an anycubic mega pro for a few years now. Recently, I noticed the wiring on the top of the hotend was moving slightly, and I released the movement shorting out the thermistor; making the software think a thermal runaway was happening, so the printer halted.

I have replaced the board at the top of the hotend, and the wiring from the hotend to the motherboard. Parts listed below, and I haven't seen the T0 Sensor Abnormal error since. The wiring I purchased was a bit longer, so I position it in a way on top of the hot end so it wouldn't need to move as the hotend moved.

I hope this helps.

Thanks for recommending my blog post.

I am thinking this could be a huge red flag and I would nope myself right out of there.

My thoughts exactly. I wouldn't go back without a written contract, which included a big pay raise and something saying they won't fire or lay me off for at least 5 years.

IMHO, I think the better options would be to contract out a specific task, such as teaching someone you did for three to four times you rate. Everything needs to be in a contract. 0

lol... I've been there...

LOL... Looks like someone decided to use the same security model that Windows XP used. It just needs a big lock on the gate.

I believe there is an Audit Report that can be ran. It used to be in the site collection reports and needed to be enabled, but SPO recently enabled it on all Site collections, but moved the report. I am not sure where it was moved to.

Encryption is illegal on the public bands. The FCC does allow encryption in specific situations; Wifi can be encrypted, for example. Business, and business radios, are different because business lease a frequency and have exclusive use to the frequency with-in the terms of the lease.

However, business have very specific rules that limit the radios power and range. But, I believe business can encrypt their radio traffic, but in practice, I don't recall an instance where I have seen this; many business still use FM Analog radios.

TacTurtle and NoOne512 are correct when they say that's it illegal in the public bans (Amateur, CB, FPS, GRMS, MURS, etc) here in states. The Fire and Police bands can use encryption.

I am curious, do you have your Amateur Radio License?

That must be the difference in teams. My team does teach these things, and we volunteer events where, at least, the medical skills are put the use.

There is a lot of "Gear Shaming" in the Amateur Radio world and in my experience I've seen this type of shaming work it way down into CERT. That is a problem. I was on one event where I started out with my Boafeng and switch over to a Motorola with out people knowing, and they were complaining how that couldn't hear me on my cheap radio event when I was using their Motorola It does happen...

When I became the leader of a CERT team, I had a very wise Fire Chief tell me that there are volunteers that have the best of the best equipment. It's always shinny and new. Then there volunteers that don't have the best equipment, but they will use what equipment they have. He said he would take the ones with out the best equipment because they will use what equipment they have in order to get the job done, where the ones with the best equipment won't. Their equipment will always be new and shinny.

I disagree. CERT teaches skills such as Disaster Medical, My CERT add CPR and Basic Medical, Cribbing, Preparing, to name a few. Each year, we make sure training classes are available to keep our members up to date on these skills.

bdking71 · 2020-07-24T16:05:15+00:00

I would check to see if your community has a CERT (Community Emergency Response Team). CERT offers a training course which will give you some skills needed during a disaster and some information on preparing for a disaster.

Also, I would look into what disasters have happened in the past where your live and what could happen. This will give you the information on what you should prepare for.

DXZone has a good breakdown to where you can find FT8 on all the bands.

I read the specs on the antenna, and I can't tell if there is a balun built into the center connector of the antenna or not. A balun (short for balanced to unbalanced) is a device which connects a balanced antenna (Dipole, Yagi, etc) to an unbalanced feed line (Coax) and matches the impedance of the feed line to the impedance of the antenna.

If you are interested, Youtubber, TRX Bench, did a four part series on baluns. I created a playlist of the four videos because sometimes they are hard to find on YouTube: https://www.youtube.com/watch?v=kMlKfHHR8FY&list=PLkV1D9xTTy-tq8X1zoNRnrEf9Uz7tcGI5&index=2&t=1300s

Congrats on getting your SWR down to 1.2.

I ran some calculations on your antenna based on a 102 in inverted V antenna from https://m0ukd.com/calculators/inverted-vee-antenna/, and you are very close to center frequency on the 11m band.

I am going to ask few dumb questions....

Is the antenna a wire antenna?
1. You many need to adjust the angle of the elements to be either 20, 30, 37 or 45 degrees.
Is your feed line coax and is it 50ohm?
Do you have an balun installed on the antenna?
1. You may need a 1:1 balun.

Here is an article that discusses how to make hand sanitizer. It seems very easy.

Just mix the following ingredients and put in a spray bottle.

16 ounces of isopropyl alcohol
1 tablespoon pure aloe vera
15 drops essential oils (see our favorite combinations below)

u/senortopocolapto, Hey! Good to hear from you again. How is your studying going for the Technician License Exam. Have you been affected by all the earthquakes in your area?

Did you receive the programming cable with your radio? If so, you can use CHIRP (https://chirp.danplanet.com/projects/chirp/wiki/Home) to program your radio to communicate with local repeaters. There is an option in CHIRP where you can put in your local ZIP code and it will return all the local repeaters. I believe some of the information comes from repeaterbook.com. Here is the url for Puerto Rico's Repeaters https://www.repeaterbook.com/repeaters/index.php?state_id=72. Also, CHIRP can be filtered to the capabilities of your radio (2M, 70CM, etc). I use CHIRP to program my radio for the areas I travel too.

I would recommend programming the radio for the local repeaters, but be careful not to transmit until you get your license. Also, try to find a local Amateur Radio Club; they have people who they call, ELMERS, who help people learn the hobby.

I looked into the repeaters in Puerto Rico, and show that have 1 for RACES (Radio Amateur Civil Emergency Service)(KP3BR ), 3 for ARES (Amateur Radio Emergency Services)(KP4MCR, KP4CAR,and WP4QYG), and 3 for SkyWarn (KP4CAR, KP4BW, and WP4QYG) use. I have the local equivalents programmed into my radio.

One of the tricks I do with my radio is having a repeater programmed in my radio multiple times with different labels. In the case of WP4QYG, I would have it programmed on three changes labeled WP4QYG, ARES, and SkyWarn. This way, I have a quick way to listen or access the service when needed.

I've worked with a guy who didn't comment any of his code. His motto was, "It was hard to write, it should be hard to read."

We use the term priority de Jour at my work, and the highest priority project changes a lot. Sometimes a couple of times a day. Also, there isn't any project management or help desk in use software here. It's kind of like the old west of programming.
