I run a repair shop and the Microswiss are pretty good, but I really dislike how they set up their heat breaks. Unfortunately there's a lot of microswiss knockoffs that are hard to distinguish from the real thing as well. So IF you go with them, make sure you're buying direct from them and not through some place like Amazon. I'm not sure why you'd even consider "Prima Creator", as the machine on their front page is a long-been-discontinued Monoprice. That doesn't instill confidence.
Honestly, why not simply get a bimetallic heat break for the CR6-SE? It uses a strain-gauge sensor for the probe, and you're not exactly going to have a good set of options when it comes to upgrading without breaking that functionality.
Importing into the EU is a PITA if you don't have the seller collect the VAT and the pain is twice if you need to RMA your purchase. So I was looking for a local reseller (preferably a Danish store) and prima creator popped up as the only alternative to microswiss.
Being a complete noob, I have no idea what's on prima's front page, so I can't judge them on that.
buuuuuut! what I have taken to heart from your post though, is why not just get the insert. I'm going to look into that instead. But can I still go into the 260-300°C range and use a hardened steel nozzle?
At the moment I'm experimenting with PETG, and it would seem that 255°C is optimal for this brand, on this printer, in this location. While the stock creality firmware will allow you to go to 260 I understand that going 250 and beyond will ruin the PTFE tube over time. And we're starting to look at maybe trying out other materials, and then the stock hotend with brass nozzle seems like a serious limitation.
Yep, you should be able to reach 290C or so with a bimetallic/titanium heat break and a hardened nozzle. Also, turn off the fan when printing with PETG and print at a lower temperature. 255C is WAY higher than PETG needs, and you're likely needing that extra temp because you haven't turned the fan off.
The fan is indeed going. I'll go print another temp tower with the fan off, thanks for the advice.
The suggested printing temp on the spool does say 230-255, so thought nothing more to it.
