@philpem @terrencefoxfur They're good bits of kit and are an STM32 trundling along at 100 MHz (I think they use that high of a speed grade on the Mini) or so at heart.

@philpem @terrencefoxfur it does sound like the 32-bit boards make a world of difference whether you're staying Marlin or going to Klipper. 2208 / 2209 drivers are souch more pleasant to have around too. I wish I could run them in UART mode rather than standalone but that can be a goal for the next printer.

@terrencefoxfur @philpem oh neat! Have you got the MMU2 or 3 and how do you find it?

@terrencefoxfur @philpem They're broadly comparable if it's a Trigorilla + 2209s Vs the silent ender 3 main board... 8-bit Mega2560 based so good for real time control but not heavy maths. One of the SKRminis is what I've looked at but I'm not sure it's worth it when the steppers could do with replacing for higher resolution ones at the same time. I may as well save the cash a build a Rat Rig or grab a used Prusa MK4 + MMU.

@terrencefoxfur @philpem Ah, yes, I've got a set of the Creality bed standoffs to replace the springs too. It's still Marlin based for now but I'm weighing up my own build of Marlin so I can use the bed probe for the Z end stop and tramming the gantry or going to Klipper which the main board can just about handle.

@philpem @terrencefoxfur That's what i've got to go on to it. I even splashed out for a real antclabs one!

@terrencefoxfur It was an Anycubic Mega S when it started out but i've given it new firmware, new stepper drivers, a real E3D Titan, and a real E3D V6 hot end (with titanium head break, plated copper heater block and Nozzle X nozzle). It's still entry level parts but the nicer end of entry level. I'm trying to add better part cooling and a bed levelling probe after which I'll probably call it done and run it until it mechanically wears out.
