PC Blend on MK4 with Prusa enclosure  

RE:

I don't own a MK4 but a MK3S+, although in this matter probably it doesn't matter the model of printer.

My setup for for PC blend  :

- Lack enclosure. - Smooth plate. - Dimafix adhesive.  - Nozzle temp: 275C . - Bed temp: 105C,

Except for very small parts, I always use a brim ( more or less large depending on the size of the part to print ).  Even so, if the model is very large and infill percentage quite high, it’s not easy to avoid a bit of warping.

As a general rule, for filaments like PC, ABS or ASA , the higher the temperature inside the enclosure, the better, provided isn’t too high for the electronics and/or the PETG parts of the printer. I’d say below 50C is safe, but above 60C probably not.  Anyway, I doubt that the Prusa enclosure, without active heating, will reach ‘dangerous’ temperatures, but this is just my wild guess. Don't blame me for a fried Buddy board. 😋 

RE:

With prusa enclosure without additional heating is not possible. Prusa beds also does not reach advertise temperature, its usually lower by 10C, I’ve made topic about it. Funny fuct is that on mini it warp less probably due better bed to heater ratio. For ASA/ABS glue stick is a must with prusa.

generally speaking if i could turn back time mk4 and enclosure would be replaced with voron 2.4r2.
