Heat temperature wire?

[jvgrago 0]

My Ultimaker 2 extended seems to have never worked right from day 1. My prints would never start, the filament just seems to never flow correctly regardless of what I have done. After attempting to print a part I needed which finished correctly it appeared I had a plugged print head. After attempting to clean it did not work I figured I could easily change it. There is a video on YouTube which walks you through changing the print head and it was a big help. But my problem is I cannot get the larger wire (temp sensor?) removed from the head and the other smaller wire did not look like the others I have seen and had no metal protruding out to grab so when I tried to unplug this I broke it.

Now I assume I will have to order this wire I am just not sure what it's called.

Also any idea how to get the other wire out? I've tried plyers but no luck.

Please let me know.

Thanks

Jim

First of all - did you remove the thin screw that holds the temp sensor and heater into the block? That's a crucial step.

You will definitely have to buy a new temp sensor. The smaller hole is the temp sensor - that's the one the people break the most often. The larger hole is for the heater. That one doesn't break as often but it can still happen.

What country are you in? If your printer is less than a year old you might be able to get free ones although - well you broke it/them. In USA you can get these parts at fbrc8.com - that's the official reseller. But I sell even better parts for less money. I test each temp sensor and heater. I test the temp sensors at 260C as many of these fail at temps above 200C. My store is gr5.org/store/. In other countries try 3dsolex.com.

I sell 3dsolex blocks to replace your existing block but once you get the wire out you can get the rest of the temp sensor out with a bolt remove tool. These are inexpensive drill bits that are shaped like a cone and that spin backwards and drill out an old destroyed bolt so you can put a new bolt in the hole. Works great for getting temp sensor out once you have already destroyed it. Same for heater.

google "screw extractor".

I just saw your photo - yeah - no wonder you wrecked it. You didn't remove the bolt that holds those 2 things in there. Get that out first!

Oh - and just to be clear - you have to replace the entire assembly which includes the temp sensor and the cable. It's not hard. Like I said, I sell them.

GR5, thank you, yes you are correct I failed to remove the screw so this is my fault. If your prices are the same or cheaper then I will purchase from you. I see your a mod, do you have access to my email? I'd like to ask you some other things as well.

Thanks
