Ooh, that's a fun machine for sure. When I started taking commissions, I moved to Elegoo for durability and RMA turnaround (they've most often sent a replacement as soon as I give them the tracking on the trouble part, which makes them almost as fast as Epax and 5x more cost-effective, IMHO).
LMK if there are any models or terrain you're looking to have printed that exceed your Mars 2 — I'd be more than happy to set it up on my Jupiters. 🤘🏼
