RE: Quick swap nozzle
For people that is swapping the nozzles very often:
- Do you clean the nozzle after extracting high temp filaments to prevent that as example PETG or ABS residual are still present next time that you will use the nozzle may be with PLA (and forget last print was ABS or PC)?
I have a special expansive cleaning filament and I used to clean my nozzles with it after printing PETG, but recently after that I noticed that several PLA support 230° I print directly some PLA that at 230° that should be able to clean-up PETG residuals.
RE: Quick swap nozzle
After printing Asa or PC I usually run some cleaning filament through the nozzle. After removing the nozzle I heat it up with a heat gun and remove all debris with a wire brush.

RE: Quick swap nozzle
So, if you want a tool-less swap of nozzles, you need:
A Nextuder nozzle ($28 -$52) or Nextruder V6 nozzle adaptor and nozzle ($30+$15)
Nextruder heater block ($13)
Mk4 Heater ($11)
Thermistor ($11)
So $87 for a hardened nozzle tooless swap hot end.
I get why they did it, I still like the REVO concept better. So $100 with some shipping. I just ordered two set ups like that. But bsides my Nk4, I'll have a Mk3.9 and an XL, so that isn't that much in the way of spares.
I can't wait to see how we migh tbe able to take the swapppable head from an XL and use it on an Mk4. Now that is what I really want. Start having problems, take it off the production machine and fool around with the trouble one offline. That's what I really want.
RE: Quick swap nozzle
Here is a link to a relevant reddit discussion. In short: The two are identical in all but cable length. It would seem the MK4 has shorter wires on the thermistor, and has a pre-relieved bend compared to the XL.
RE: Quick swap nozzle
Inreresting that they mention if you have to use thermal paste. I don't remember any building the Mk4? The nozzle and heater cartridge were already in place, IIRC? Just the thermistor had to be put in?
Does anyone use hightemp anti-sieze on the nozzles? I knwo there is 'high-temp' but I wonder if that refers to 300C...

RE: Quick swap nozzle
The Prusa nozzles don't need torquing down, just a finger-tighten suffices. I've been able to swap those nozzles easily. Not sure about using the adaptor - though I'm a bit irritated that they put a proper Obxideon nozzle up for sale the day I get a hotend to fit with an adaptor and a NozzleX
