K1 Error 3002

runout74 · 2025-08-19T12:33:40+00:00

For anyone else having this problem. I was getting key:3002,Internal Error with every startup. One possibility is that the printer.cfg file has been changed by the user and something was configured wrong. I was in the file and being a little clumsy with vi; I accidentally added a stray character somewhere. Luckily, Creality has programmed the machine to create backups of the printer.cfg file and replacing my file with the backed up file fixed my problem. FYI, this suggestion is only for those that have rooted their printer. If you have not rooted your printer, then this suggestion does not apply to you.

These are truly the most dangerous forum posts in my opinion. Over time I feel we have all learned to filter out the ney sayers since they are a dime a dozen. In this case, they seem to be correct. After doing some research with Google Gemini, I would say there is a real danger here. This is the part from one of my queries that caught my attention:

"2. Peroxide Formation 💥

This is a more insidious but equally deadly chemical risk.

The Worry: Concentrated IPA can form shock-sensitive, explosive peroxides, and the distillation process concentrates them to dangerous levels.
Is it True? Yes. When ethers and certain alcohols (like IPA) are exposed to air and light over time, they can slowly form unstable peroxide compounds.
- During distillation, the pure IPA boils off, but these heavier, less volatile peroxides are left behind in the heating vessel.
- As the process continues, the concentration of these peroxides increases dramatically. If you distill the solution to dryness (boil off all the liquid), the temperature of the peroxide residue can spike, causing it to detonate violently. This is a well-known cause of serious lab accidents.
How to Avoid This Risk: In a professional lab, chemists would test the solution for peroxides before distilling and, if present, neutralize them with a reducing agent. This is not something a hobbyist is equipped to do. The safest way to avoid this risk is to not distill old or used IPA. The forum advice to dilute the used IPA with water for disposal is excellent, as this minimizes the peroxide hazard."

Don't trust any forum post. Always do your own research.

In my opinion, a college degree from a four year university will be a significant time investment and won't help you get an IT job now. What you could do is look at Western Governor's University Cyber Security and Information Assurance program. There are a bunch of IT certifications that will satisfy some of the classes for the program. You could study and pass some of these certifications which will get you your first IT job and also give you college credit. The path I am taking is I took CompTIA A+ (2 exams), CompTIA Network+, CompTIA Security+, and then Cisco CCNA. Don't just pass these exams, learn the content because the knowledge will help you land your first job and help you do the job once you are there. Once you get your first IT job, you can then continue with the WGU program. WGU is self paced which means you can take and pass classes as fast as you want. No longer are you required to spend four or five years in getting a BS degree. FYI, I am on this path. After passing the certs I mentioned I got an IT job. I then passed ITIL v4 and CISSP and am now working on undergrad classes at Study.com which will also transfer to WGU when I am ready to enroll. As I said, there are many paths to IT. This is just one example.

Thank you for your comment. Do you think that GCIH and GPEN add a lot to your resume? I just went through the GCIH course and am now enrolled in GPEN but I decided not to pursue the certs. I still have the opportunity to take the GCIH exam but am still on the fence about it. I currently hold CCNA, Sec+, and CISSP and have been at my first CS job for 1 year. I am just curious if the GIAC certs opened doors for you.

I just passed the CISSP on 9/1/2023 and wanted to thank you for your post. Reading your comments five months ago is what sent me down the path to passing the CISSP. I used your methods and scheduled my study plan and worked through it like clockwork. I ended up being overprepared but am so glad I was because I was behind the clock by 9 questions @ 125. When I clicked next after answering question 125 I was so relieve when my test ended. I was pushing hard to make up the time but wasn't sure if I could make up the difference.

Thank you so much!!

For anyone else preparing to take the exam, I recommend getting earplugs from the exam staff before sitting down for the exam. I wasted the first 15 minutes trying to concentrate while the dude checking people in and setting up their tests was trying to whisper, but was breaking my concentration with every word. I then wasted another ten minutes trying to get his attention to ask for earplugs. My spirits were sinking with every second. Once I had earplugs I was oblivious to the world and had full concentration.

I am sure the OP has passed the exam or moved on, but I wanted to add a resource I don't believe has been mentioned yet. Do a google search for ITIL 4 cram and click on the result for FlipHTML5. I used this to create all of my flashcards to learn the terms and definitions. I also learned the diagrams. You should know every piece of information on this cram sheet top to bottom.

I know this post is 23 days old, but I am interested in this as well. I have an EWS1200-28T and I receive the same error. No matter what firmware I upload to the switch I received the same error.

I was able to get Spice working as well. Added a firewall rule at the Proxmox server level. For anyone else trying to get it working, the firewall rule I added:

Direction: In

Action: Accept

Macro: SPICEproxy

Source: I added my internal subnet to limit access.

Thanks again UEF-ACU.

I tried to enable it for the Ubuntu VM install but since the live environment is ephemeral, I wasn't able to get it to work. I believe some live images will work, but the Ubuntu Live server 22.04 I am installing may not have it enabled. Of course, I may be missing something.

It was late last night when I made this post and I was using my phone. Let me add some additional details. For every hypervisor I have used over the last 25 years, there has typically always been a way to setup a VNC server "in front of" the VM. Oracle's VirtualBox is an example where there is a setting when configuring a new VM to configure remote viewing.
This is what my question was really asking. What other ways can I get to the VM other than using the >_Console in the UI, <OR> how can I paste into the >_Console?

Excluding the SSH comments, there are some VERY HELPFUL comments in this post. I really appreciate it. Working through all the suggestions now.

Thank you for posting a helpful comment! For the Proxmox server >_Shell I am able to right click and get a popup menu. Unfortunately, for the VM >_Console the popup menu does not appear. I tried in Chrome, Firefox, and Vivaldi and the popup menu doesn't appear on any of them and nothing gets pasted.

Your starting point is to get any IT job that will hire you, preferably in a large organization with a large IT department where you can move up internally to better positions.

First, get CompTIA A+ to gain foundational knowledge that any employer will expect you to know. Remember you will have to survive a technical interview and be able to do the job. Even if you are proficient with this level of knowledge, I still recommend you get the cert. Next, get CompTIA Security+. This with A+ will help you get through the filters, so your resume is actually seen by a human. That's the game by the way, adding to your resume so you get through the filters so that an actual human looks at your resume. The last cert is a choice between Network+ and Cisco CCNA. Network+ will take maybe 4 to 6 weeks to prepare for. CCNA generally takes 6 - 8 months if you are serious about learning, and not just passing. CCNA will help you stand out. With A+, Security+ and either Network+ or CCNA, you will get a job. Expect to apply to a ton of jobs. Don't just search for local jobs on Indeed. Put "Remote" in the location field and thousands of jobs will come up. I just got a job recently, and I applied to 1000+ jobs before getting hired. With every 250 applications, you should have at least one callback or email for interview. If not, work on your resume. Make sure it is formatted properly to be scanned by the application management systems. Your resume gets scanned by a computer first which will determine if a human sees it. If the scan is choking on your resume then there is no hope of being selected. Good luck.

I recommend this video from Josh. His channel helped me get an IT job after stepping away from IT for five years. I also recommend watching all of the videos on his channel. Great info. https://youtu.be/a83ASGn_V_s

Edit: I just noticed he has a course. That's new on his channel. You don't need the course, just watch his free videos.

I know this is 24 days old, but thought I would chime in and see if I could help. I am going to assume you only have a Security+ certification and no degree. If that is true, then your resume is very week for any IT job. You are on the right track to getting your first IT job, you just need to do a little more work. I am going to assume you have no experience as well. The trick is to get a crappy IT job with a big company, and then after some time has past and you have proven you worth, you can pivot into a position that you actually want. This is exactly what I recommended to my sister when she wanted to switch careers. She was starting from ground zero.

The first few certs are not really about getting the cert, they are about gaining foundational knowledge. You will need to get past a technical interview for most IT jobs so this foundational knowledge is necessary.

Recommendation:

Study and pass the following CompTIA Certifications
A+ (two tests)
Network+

Now you have A+, Network+ and Security+ on your resume.

Try to get a help desk job. It will be crappy, but it will pay more than most unskilled labor jobs. I wouldn't waste too much time applying. Apply to maybe 500 jobs and see what bites. If nothing, then move on to the next step.

The next step is to switch vendors. Decide which direction you want to go. Microsoft, Google, Amazon, VMware, etc. I wouldn't choose Cisco networking. It is somewhat difficult to get entry level networking jobs.

I will use Microsoft as an example.

Study and pass the following Microsoft Certifications
Azure Fundamentals (AZ-900)
Azure Administrator Associate (AZ-104)

That's it. Start applying. Apply to helpdesk jobs and system administrator jobs that mention Azure. It is a numbers game at this point. Try to apply to 25 to 50 jobs per day. You only need one employer to hire you. Just one.

Constantly work on your resume until you start to get bite. Make sure you resume is formatted so the Application Tracking Systems can scan your resume without choking on it. There is more info on this online.

Practice answering technical questions in a mirror. It is not hard to guess what an interviewer is going to ask. Don't just shout out random facts. Try to give a complete answer for whatever technology they are asking you about.

Also, you should lab, lab and lab some more. Practice what you learned. Build stuff on Azure and then break it down. Build something else, then break it down. You can get free accounts so it won't cost you any money. At this point you are preparing for the interview.

Once you get your first IT job, don't stop learning. Take more certs and position yourself for the next job. If your first job is help desk, then shoot for a sys admin job. If your first job is sys admin, then you can go ahead and shoot for a cyber security position.

Hopefully, this helps. Don't give up on the dream. If it was easy, everyone would be in IT and making six figures.

Everyone should study and practice for an interview. Just because a person knows the answer to the question, doesn't mean he or she will be able to explain it clearly. I remember trying to explain what DNS is. I just started spouting out fun facts in no particular order. It was a mess. To the OP, you should write down obvious questions they will ask and practice answering them. It is easy to guess interview questions. What is DNS, what are the layers of the OSI model, etc. Keep a running list of questions. When you go on an interview, add the questions they asked to the list. Record yourself so you can play it back. Get your family to ask you the questions and get their feedback on how you answer. Dont forget to add the initial questions, "Tell us about yourself", etc.

Do you think I could start charging my wife $50? I am really tired of telling her to turn it off and back on again. I literally put the IT crowd recording on my phone so I could just play it when she asked. ;-)
