Tolerance issues.
I am running into quite honestly appalling tolerance issues with my RR. I will print parts that are 300x300x300 and they will measure as close as possible to 300mm³ as can be. But when it comes to printing parts that fit together, printing holes for pins, it leave a lot to be desired.
e.g. my ender 2 i could go down to a 0.05mm tolerance. need a 2.5mm pin to fit in a hole? make the hole 2.55mm in cad and it will fit.
But i am at a point now with my RR that even a 0.3mm tolerance isn't cutting it. and it seems to be getting worse the more i use it.
has anyone else faced issues with terrible +/- tolerances, or are my expectations too great from a previously better machine?

I have the bondtech LGX lite, RR Vcore 3.0, and rapido hotend.
Internal holes have to be adjusted in the slicer to come out correctly

Thankyou for a quick responsr. Do you know (in prusaslicer) what this setting might be?
I haven't tried yet in cura, which I was using for my 5 other / previous printers, because there was no RR profile for Cura which worked.
Sounds like it might be an issue using Arachne instead of classic for slicing?
I would try
XY compensation inner

Thank you, sadly Pruaslicer combines both settings into one. Shame, as that could have been the solution. Oh well, at least i know it is slicer related now
I will have a look at superslicer though. Thank you again
I often find reducing extrusion multiplier by 0.05 helps

I have a feeling the reason why my "previous" printer was so accurate when it came to holes, was probably some slight and consistent under extrusion i never noticed. Interestingly in Superslicer the default RR profile has extrusion multiplier at just 0.93, whereas Prusaslicer set it to 1.0
I think my RR profile is closer to 0.90 in SS, even though I've measured esteps and double checked them, the same filament in PS works well at closer to 0.95. 🤷🏼♀️
