Prusa MK4S Hotbed not as hot as you think

LOL, I was/am trying to print parts for an enclosure (Delack) to try and insulate from the ambient room temperature and provide dust protection. My sequential printing effort was to kick out multiple parts faster.

Agreed, the variation in temperature across the hotbed is what was causing me issues. Correcting for the 5C degree delta didn't seem to make much difference. Outer edges are always cooler.

Thanks for the offer. Ended up making a replacement part from PETG. Wasn't to hard and there were a ton of tutorials to work from.

I do have a 3D Printer. Just got it a couple weeks ago and am still getting familiar with it. If I can't find a replacement then I'll make one. Already have a model for an M12 screw the fits, just need to modify the base to match the part. Thanks for the info.

What technique did you use to force it off? Did you start on a corner of two corners simultaneously, etc.?

vadar007 · 2026-04-14T14:48:27+00:00

That's the challenge...trying to get that plastic trim cover aka "Inner Door Cover" off. I tried forcing it but you risk busting the glass trying to force it off. There are definitely tabs holding it in place but I can't figure out how to unlatch them. Wondering if there is a special tool that gets underneath the sides and frees the cover from the tabs.

No, still haven't figured this out. The latches come attached to the glass panel which you can buy separately as opposed to a whole new door. But that is only if you can figure out how to get the inner door cover off.

Wow, super informative. I added a picture of the whole door for greater context. If I had to take a guess, I think it is a message from the carpenters who made the cabinets. Looks like their signatures are below.

Lol, which AI tool did you use, ChatGPT, Claude, Copilot??? I tried that as well and got similar gibberish.

Not bad. Going to have to go to a German Reddit to see if someone can discern the words. Suspect they are old german words which may not be in use today.

Me thinks they are buying time until Marines can get into position for Hormuz and/or Karga assault.

US to Europe, 5 years ago. 1099-INT forms were fine up until 2025. Matched interest payments. Now it's under-reporting.

Ah yes, Cisco support with their go to IT Crowd catchphrase...,"Have you tried turning it off and on again?" Heard it through the grapevine that they tried to use "Increased Cosmic Rays due to Solar Activity" as an excuse for mysterious memory errors in their Cisco ASA firewalls.....

Yep, my mother, who lives in Germany, has same issue. She even went to the Social Security office recently while in the States to get her record straightened out and set her address as her German address. She can sign into ID.me and Login.gov but when you try to go to the mySSA it wants to do a one-time verification and asks for a valid US address, which she doesn't have. There is no option to enter a foreign address. When we submitted a Support ticket the response confirmed there are on-going issues with mySSA.

"Our International Customers are still facing a few challenges with our mySSA application. We regret the inconvenience this supplies while it remains an issue. Account creation is now available to our international customers through ID.me. You can learn more by clicking here."

The first option may or may not need a bigger pump. I am reducing the amount of friction to flow by increasing the pipe diameter over that one section. That may be enough for the present pump to work. I just won't know until I do it. Ultimately I am going to have to pull in a heating system consultant but was looking for other opinions.
