I know someone personally that mills with it, and I know of others from youtube, euros mostly. It seems to handle the heat well and there arent any major mill related issues. Some of these people mill 60” poplars no problems.
What you need to know is about these 2 more general issues with this saw:
Top dog case support is a bit flimsy and breaks pretty often during impact or twist motion, and I think starting with somewhere in 2023 production year they thickened that area.
Second issue is the air filter cover, the base seems to be flimsy too together with the cover, and vibration will make the plastic cover “eat” through the magnesium base after enough run hours ( 500+ hours), and I dont think that was improved yet. So you’ll need to find a way to dampen the contact area between the cover and the base. Some thin rubber or something is what I’d use. Enjoy the saw, nothing is ever perfect, so dont stress too much.
