I'm having issues with my track saw when cutting 8/4 walnut. Even after making five passes, it's still producing enough smoke to cook a turkey, and I'm worried about safety! Could this be due to the wood's tension against the blade or perhaps because I'm not using a riving knife? I really want to figure this out since I'm concerned about my dust collection catching fire. For reference, I'm cutting with the saw set to full speed on a 4-foot piece at a 90-degree angle.

Definitely consider if the blade is dull or just not suited for ripping hardwood. You should also check to make sure your saw is properly aligned with the track; any misalignment can cause extra friction and heat.
I faced a similar problem with thick materials too! What worked for me was making an initial rough cut that's slightly heavy, like 1/16" to 1/8". Then, I would come back with a finishing cut. Also, consider switching to a ripping blade; that really saved me from burning.
First off, check the direction of the blade. Sometimes a simple mistake can cause a lot of issues! Also, pitch build-up could be a culprit – that stuff can heat up pretty quickly when it clogs the teeth.

Great tip! I hadn't thought of doing a preliminary cut. I'll definitely look into getting a ripping blade!
