CTC Dual Hot End - "upgrade"

[noiseboy72]

I've done more than 500 hours on the standard setup, including ABS PLA and Ninjaflex, so I don't think you need to replace the whole thing.

Regarding the thermocouples, if they look like this image, they need insulating. Personally, I would leave on the originals, as they won't be very different to the new ones. Thermocouples don't vary anywhere near as much as thermisters.

Hi Guys

Thought i would update the thread now I am (for now...ish) fixed.

I bought parts to be able to move to threaded throats or retain the originals, and did that - with the common silver aluminium extruders - that has really helped.

I printed off a rear bracket and as the new extruders were threaded I have ptfe tube in place end to end, which saves continually watching the printer for snagging.

The new extruders seem to have no problems haulling tthe filament through the tube which is great.

I wanted a modified top plate to protect the cables - most dont work with the threaded ptfe tubes going directly into the extruders - and prevent the tensoon lever working. They all seem to be threaded into the top plate which would be less than ideal in terms of alignment, or at least they would be on my printer.

Lastly - a comment re these aluminium extruders - I had to insert a washer between the stepper and bar to ensure that the exit extruder feed is perfectly aligned with the throat - as supplied they are a mile off.

All in, a huge step forward in quality.

Thanks for the advice!
