Hakko CHP-170 micro cutter, the same I use for filament to cut off the end when changing filaments

Good tool for the toolbox and nicely priced.

We apologize for our negligence that we overlook the differences of the connectors between early batches and later ones.
Thanks so much for Jetguy’s explanation and helpful instructions.
Either removing the pin from the ribbon cable side or cutting the pin from the protector can work. However, from our perspective, removing the pin should be safer.
Anyone with the same problem due to the earlier batches, please try to take out the pin from ribbon cable’s connector carefully with tweezers. Anything still unsolved on this, please feel free to let us know. Below picture (source from Jetguy’s previous instruction post) is for your reference.

In my experience, removing said pin from the connector is easiest with small needle nose pliers - flex it back and forth a few times and it will break off at the base. Easier than trying to snip it off down inside the socket.

I have those same Hakko clippers. Highly recommended.

The pin was too far in the connector to reach so had to cut the correseponding pin in the protector board.

I tried both a micro cutter and needle nose pliers - it was harder than I thought. All pins around it were bent but the micro cutter did the job although it was hard to reach the lower end of the pin.

I straightened the pins a bit again (needle nose pliers did that the best) and connected the protector. So not really a plug and play job.

Vicki, I emailed sales early last week in response to my order for this along with the filament run out sensor that was ordered and paid for on 3/8/2018. I have not received any response from them. Any chance you can prod them into a response.


Please PM your purchase information and your contacts to me.


thanks, i got a thermal protection!

To JetGuy: Is there a better cable solution that you know of or are using that you could point me towards? Btw, thank you for your full write-up of the need for thermal runaway protection.

I've got a situation here.
Can't disassemble it bcoz a white glue or silicone everywhere.
And I don't wanna break a thing.
:? :(

John, sadly, the fix is either I trade you pre modified mainboards, or you just go ahead and do this free safety module and do the simple pin mod. I'll help you as best I can and I am one of the closer members to you.

Thanks you for the offer JetGuy. I have, of course, ordered the fix along with the filament run-out sensor.

Sorry, I didn't make myself clear JetGuy. I was referring to a better cable solution as in replace the existing cable with one that has better flex or more robustness to avoid the cable breakage problem for the longest time possible. I tried to find an article you wrote a while ago where you refer to replacing the ribbon cable with something else. I'm not sure if you were referring to to an N1 or N2 and I couldn't find what you wrote again.

I'm also thinking that other industries must have solutions for moving electrical connections that will not break. Perhaps it is a matter of overall machine design -- as in designing a motion system that does not expose the electrical connections to so much stress. I'm guessing you have probably given this topic a lot of thought and action.

There are ribbon cables designed for high flex life

Well that is certainly cool. Do we know that the cable R3D is using is any different?

Anyone know how long the cable is?

have these all shipped out? I thought I placed my order for the free thermal protector and I haven't seen anything yet.

I do not have a measurement but know it's about 2 meters. One fact that happens here is both the shorter N2 and N2Plus, and maybe even the N1 all share the same length ribbon cable and a massive amount is bundled into the base of every one of these printer.

found my reply back to my request on feb 27, nothing seen or heard since.

kinda makes me sad since it was my printer that exposed this issue.

Please shoot me a PM. Will ask the local team to help check out your shipping.

When will these be standard, ie. pre-installed, on new N2 series printers?

The latest batch of N series in factory had been installed with Thermal Protector by origin.
On the new Pro2 series', the function of Thermal Protector has been integrated onto the Motion Controller Board.

Thanks JetGuy. Are you using the standard cable?

Yes, just using the factory ribbon cable but with mainboards modified before the protection board was ever produced. As such, if I do have a cable failure, there is so much length I can just cut off the bad section (most likely to fail at the flexing at the extruder end anyway) pull fresh wire through, crimp a new end on and go.
