  • I’ve almost always used PrusaSlicer just because the only printers I had access to were mk3s+.

    I’ve started playing with Cura though because A. i wanted some more complex prints that PrusaSlicer struggled to support, and B. We also got some creality cr-30’s functional at my college again. So far I still feel Prusa is easier but that’s likely just familiarity.






  • Sure, but on these fully DC printers all the power control hardware is integrated into the main board and supplied from a single main power rail. You’d have to basically build a separate power control board with that would allow you to isolate those MOSFET’s on their own power rail and then jump the PWM control signal over to it from the main board. Decent amount of electronics knowledge and skill required to pull that off.



  • Layer adhesion almost always means plastic is extruding too cold. Especially if the adhesion problems are happening on layers off the build plate. Keep bumping the temp and maybe use less part cooling fan- you can’t really make it worse at this point.

    Hardened steel nozzles do not conduct heat nearly as well as typical brass nozzles. (The thermal conductivity of steel is around 40w/m-K for high alloys, while for brass it is 110w/m-K). It cannot heat the plastic up nearly as fast.

    I usually start at 210C for PLA on my Prusa mk3’s with a brass nozzle, and will back down to 200/205 if there’s more overhangs or too much stringing. But on the printer set up with a steel nozzle I ended up around 225C to get results comparable to 210 on the brass nozzle.


  • I also have a zen4 cpu.

    The 30 second boots are memory training. The motherboard is basically training itself on how the DDR5 memory modules respond on every signal wire and it can be inordinately slow depending in memory amount. For whatever reason, AMD DDR5 systems are slower at it than comparable Intel DDR5 systems.

    Update your BIOS to the latest version then enabled “Memory Context Restore”. The bios will then save the last training results and stop taking 30 seconds to start up.
