A bit late to the party, but personally I’d start with swapping the extruder for something newer and going from there. The F410 gantry was designed for a bowden style carriage, and is prone to racking under heavier loads, so a direct drive extruder may solve some issues, but cause other new ones. You’d also have to re-design the entire X-axis carriage as there isn’t an easy way to adapt an extruder, and Fusion3 still hasn’t released their files for it.
The stock extruder is based on the classic Wade’s style extruder, which is still a decent extruder, but any recent extruder, be it a Bondtech or other would be a noticeable upgrade over what you have currently. The good news is, as the F410 uses a Duet 2 controller, swapping out the extruder for say a Bondtech BMG is pretty easy, you should be able to use the existing mounts on the chassis, and just need to update your eSteps for the extruder. I’d add in some capricorn tubing and go from there. If you’re wanting to go the direct drive route, I’d look at the FYSETEC Orbitor extruder, it’s currently one of the smallest extruders on the market, and based off an open source design (the CAD files are on Thingiverse and GitHub) so integrating that would be fairly simple, and result in a much smaller toolhead over other options.
