Broken Printhead

[Sam Ferguson]

The printhead tip broke off on my CubeX when I tried to clear a jam.  I tried to put a little high-temp JB Weld on it but that didn't work (it slid off after heating up the filament).  Any ideas out there? Or should I just order another printhead?

Very useful ! You can reuse it with a custom nozzle. Unscrew the broken part and you can use a m6 heaterblock/nozzle with a 200k or 230k (better) thermistor.

Good advise. 

Or one of these.

[Hugues]

I also ordered one ! But i've to wait they are out of stock.

[Rodney Wells]

Are they out of stock?  I just purchased a 3mm .4 nozzel for my 3D touch.  With out a doubt this hot end on my CubeX combined with Kisslicer 1.4.4.4.9 is producing some of the best prints.  The photo is of PCB stand-off  I made in PLA because of there size building them is often a problem and has always been very difficult in PLA.

I bought the 1.75 version in parts, not the full kit, and it's out of stock.
I will try in 0.3 nozzle.

Hi 

Giovanni V Sent me some T-Glase PETT To Test for a model plane on the New Hot End.  

This is the T-Glase print  

[Sam Ferguson]

So, it looks like you've made a custom print tip. Looks like it works pretty well.  How do you convert a CubeX to use one of these?

[Hugues]

You can read the thread nozzle head swap, you you find several ways to do this, I also posted a video on YouTube with a custom merlin hot end.

We are going to launch an eshop with the good thermistor, tested hot end and some other accessories for our cubex. We hope it will be ready for September.

I will draw you a CAD file on this. 

[Rodney Wells]

I deleted the other files.  sent the incorrect file.

Thanks Rodney, so does the ExtruderRFIX_X fit into the Adapter?

I recommend you print it in ABS then slot the triangle piece into the Hot end then glue the adapter to the triangle assembly, the adapter should print 10 mm diameter. insert that into the CubeX extruder.  the Hot end is very well cooled and the ABS plastic adapter will not melt.   But If you have the facilitates and Aluminium manufacturer version would be better. 

Not in the file how they are positioned one on top of the other but not connected, insert the hot end and then join as the are aliened in the file.

I repaired one prithead with:

One M6 screw and the follows steps:

- Drill the printhead with 5 mm. bit. Depth about 5 mm.

- make an internal thead M6.

- Make a drill with a 3 mm. bit at the center of the screw, about 10 mm. depth.

- Join the both parts with the drilled screw, measure the clear distance between the printhead and the cooler.

- Unmount the drilled screw, cut it the length that you measured before.

- Join again both parts using Loctite Threadlock 2400 or similar.

or if you can find an 6 mm brake regulator for bikes, you can use it and don't need to drill the screw.

Sorry for my English.
