Upgraded hotend availablility  

RE: Upgraded hotend availablility

Hello,

I'm using a CHC (Ceramic) hotend (for MK4/XL/CORE ONE) >320ºC.

Note: I have compile myself the firmware (to use up 350º)

Bye

RE: Upgraded hotend availablility

Please add some more info, how is it working, how much have you tested ? This is a very important question since its the single biggest weak point of the CoreOne. I wish Prusa could supply an upgrade kit for us that want just a slight more temperature(like many competitors have) for the new engineering materials that are available now.

I disagree. The pronounced belt ripple, limited build volume due to MK4 backward compatibility, rudimentary camera option, and lack of a well-integrated MMU are probably all affecting many more users than the limitation on hotend temperature.

And if you are interested in high-temperature filaments, the lack of active chamber heating and a proper recirculating filter solution might be added to the list.

The engineering filaments is what i am interested in and why i just bought 2 ad5m instead of core ones. I couldn't justify the price if i was only going to be able to print pla and petg.

Hello,

I bought them (four) 10 days ago. At the moment they are working very well but I have to test high temperatures, for example I want to try PPS-CF10 filament (carbon fiber-reinforced polyphenylene sulfide composite), It needs 310-350º to be printed.

Pps-cf is the same filament i'm wanting to try as well. I have a k2 plus but extruder quality issues are leading me to explore other options and prusa of course has an extremely good reputation.

Pleas provide some information when you have done some more testing, would be nice to see both PPA temperatures (300-320) and PPS temperatures(up to 350). And if it seems like it can still keep the correct first layer calibration, that seems to be an issue with some printers like Qidi plus4 when running really high temperatures.
