haha - you say it...I dreamed of switching nozzles, filaments, ... but actually what you want is to tune everything for one nozzle and one filament and never touch it again 😀
RE:
This reeks of AI so I’d take this with a grain of salt. With that said, maybe something change with the Revo Mini’s in the modern day? I’m also seeing large improvements in print quality from reducing the temperatures. In the case of PLA, reducing the temperature by 20-30C from 220C took me from pretty rough benchy’s to matching the Mini’s stock print quality. I dug into this very deeply, I printed a couple dozen benchy’s. I isolated as many variables as I could between the Bowden tube, extruder, mechanical assembly, part cooling, heater core, etc to debug my bad print quality but ultimately it seems that the Revo Micro just prints hot compared to my stock hot end. The only thing that seemed to help compared to lowering the temperature was printing a fan duct mod.
I guess I’m stuck tuning in all the filament profiles manually now 😔 not quite the plug and play experience I had with my MK3 on Revo.
RE: Revo Micro installation on my Mini+
That is very strange, as it should be the opposite, in terms of temperature (I am assuming you have the v2 mount).
If everything in the bowden tube is ok (e.g. the tube is not moving during retractions), the first thing i would try is to reduce the retraction lenght from stock 3.2mm to 2.0mm. I had the bowden tube moving because the fittings were not grabbing it properly; that gave me all sorts of problems, but 3.2mm retraction seemed fine.
After I solved that issue though, I started to have heatcreep with 3.2mm retraction, so i lowered it to 2.0mm and that solved it for good.
I would try that, otherwise looks like the issue is located in the thermistor/heater area or its connections to the board. 190°C seems too low for the revo, i almost clogged mine when printing a temp tower below 205°C.
P.S. also make sure that the nozzle is screwed all the way, as sometimes improper thread catching or spring positioning may make it feel like the nozzle is seated properly, while it is not
